USB Inrush Testing.

The USB spec has limits on the ‘inrush current’

which is designed to prevent you from having 2000uF of capacitance that must be suddenly charged when your board is plugged into the USB port.
The limit works out to around 10uF of capacitance.
Your board might have much much more – so you’ll have to switch portions of your board on later with FETs as a soft-start.
For the ChipWhisperer-Lite, I naturally switch the FPGA + analog circuitry as to meet the 2.5 mA suspend current.

Thus I only have to ensure the 3.3V supply for the SAM3U2C meets the inrush limits

which is a fairly easy task.
This blog post describes how I did this testing.
The official USB Test Specs for inrush current testing describe the use of the Tektronix TCP202 which is $2000, and I don’t think I’d use again a lot.
Thus I’m describing my cheaper/easier method.

I used a differential probe (part of the ChipWhisperer project

so you can see schematics) to measure the current across a 0.22 ohm shunt resistor.
The value was selected as I happened to have one around… you might want a smaller value (0.1 ohm say) even, as the voltage drop across this will reduce the voltage to your device.
The differential probe has enough gain to give your scope a fairly clean signal.
This shows my test board, where the differential probe is plugged into a simple 2-pin header: From the bottom, you can see where I cut the USB shield to bring the +5V line through the shunt: To calibrate the shunt + gain from the diff-probe, I just used some test loads, where I measure the current flowing through them with a DMM.
You can then figure out the equation for converting the scope measurement to a current in amps.
Finally, we plug in our actual board.

Here I’ve plugged in the ChipWhisperer-Lite prototype

The following figure shows the measurement after I’ve used a math channel in PicoScope to convert the voltage to a current measurement, and I’ve annotated where some of these spikes come from: Saving the data, .

We can run through the USB Electrical Analysis Tool 2.0 to get a test result

The USB-IF tool assumes your scope saves the files with time in seconds and current in amps.

The PicoScope .csv files have time in miliseconds

so you need to import the file into Excel, divide the column by 1000, and save the file again.

Finally you should get something like this: Note the inrush charge is > 50mC

but there is an automatic waiver for anything < 150 mC. While the system would be OK due to the waiver, I would prefer to avoid exceeding the 50 mC limit. In this case there’s an easy solution – I can delay the USB enumeration slightly from processor power-on, which limits the inrush to only the charging of the capacitors (which is done by ~15mS). This results in about 47 mC. This means I’ve got about 100 mC of headroom before I exceed the official limits. This extra headroom is needed in case of differences due to my use of the shunt for example. In addition, I should be adjusting the soft-start FET gate resistor to reduce the size of that huge soft-start spike. Ideally the capacitor charging shouldn’t draw more than the 500mA I claim when I enumerate, so that’s a little out of spec as-is. If I don’t want to change hardware I could consider using PWM on the FET gate even… March 2, 2015March 3, 2015 ChipWhisperer-Lite, tutorial, usb 1 Comment on USB Inrush Testing.

2017 Coding with Empathy in 2017

Empathy – the 4th most popular word in 2017

according to Merriam-Webster.
It’s interesting that this word has risen up in its popularity this year.

Mirriam-Webster also points out the connection between politics in the USA

and the increase usage and searches for empathy.
Here’s Google’s take on how empathy is doing 2017.
This is a trend graph compared to sympathy and compassion: So, definitely something people are becoming more aware of, and possibly also exploring.
The Blog.
This blog hasn’t been as active as in 2016, but there has been some activity.
3 of my most popular blog posts came out this year, and have been well-received both on this blog and on the great platform.

Rituals of Shaming in the Software Industry

Efficiency and Effectiveness in Software Development Teams

Please, break the build!.
As announced in the 2016 summary, I explored video this year, with a month of daily vlog episodes exploring daily reflections on The Daily Stoic by Ryan Holiday.
I was inspired by two of Ryan Holiday’s previous books; The Obstacle is the Way and Ego is the Enemy.

These introduced me to Stoicism

and how valuable this philosophy is.
The 30 episodes of the Vlog was an eye-opening experience for me, on a personal and professional level.
I found new joy in editing videos, learning about stoicism, and combining this with a daily journal that also doubled up as a vlog.
Feel free to check out the results, and let me know what you think: Conference talks / Podcasts.
Empathy was also in focus on the conference scene this year, as I presented at NDC Oslo and QCon New York.
Both talks are recorded and are available.
I’m really happy with how these talks turned out, and the feedback from them.
Though they are very similar, .

I think the second iteration at QCon NYC really struck home

I also had the chance to have a chat with Shawn Hastie for the InfoQ Engineering Culture Podcast where we dove into topics of team leadership and empathy.
It was a good chat, and certainly something I’d love to do more of.

Pavneet Saund on Practical Empathy on the InfoQ Engineering Culture Podcast

I can’t have a summary of 2017 without mentioning the #goofyreligion group on twitter.
What started out as a joke by Dave Rael quickly escalated to a hash-tag a few of us rallied around to help motivate each other to take care of our health, physical and mental.
The tweet that started it all: To learn more about the #goofyreligion and also a great conversation on balance and functional programming check out Reid Evans on the Developer on Fire Podcast Gratitude.
The second half of 2017 has been about gratitude for me.
Not so much about external gratitude, but internal.
Appreciating the people around me.
Putting them in focus after a lot of focus on myself and my activities.
I suppose it’s about balance, really.
I spend time doing these things in public to help others, but at the end of the day I also need to be there for the people around me.
So a special thank you to my wife, kids and family.
I want to thank the wonderful people at KomplettDev.
It’s a joy to work with so many individuals bringing their whole selves to work every day and building the best web-shops in Europe.
I also want to thank the #goofyreligion gang (with friends).
These people inspire with their actions, and their words.
I’m lucky to have you, and looking forward to sharing the #goofyreligion with more people in 2018.
A special thank you to Emil Cardell for giving me a journal and pen after the NDC Oslo talk.
I now journal every day and am better for it.
150 days of journaling so far this year.
Looking Forward.
I’m striving for balance, and finding a healthy way to push myself on all fronts.
I’ve discovered this means tackling some bad habits I’ve built up through my life and understanding that changing my mindset is going to be hard.
A keyword here is rewiring habits.
There are also some new things happening, which have me really excited and I hope to share more of that in 2018.
Finally I’d like to thank each and every one of you readers for putting empathy in your lives, and for those around you.
I’ve seen a lot of positivity in our communities that give me a lot of hope of bringing safety into our profession.
But there’s a long way to go yet.
So, let’s continue our work in 2018.

Ultrasonic Sensor with Raspberry Pi

Ultrasonic Sensor with Raspberry Pi.
April 22, 2018April 28, 2019 2 Comments hc sr04 raspberry pi example, hc sr04 raspberry pi library, hc-sr04, hc-sr04 ultrasonic range sensor, hc-sr04 ultrasonic sensor, OLED, pyaudio, , python ssd1306 oled, raspberry pi distance sensor, ultrasonic sensor, ultrasonic sensor raspberry pi tutorial Measuring distance using Ultrasonic Sensor with Raspberry Pi – Python – HC-SR04.
Today we are going to see how to measure distance using HC-SR04 Ultrasonic sensor with Raspberry Pi.
How to measure distance of an object?.
If you want measure the distance between you and the object in interest, there are quiet a few methods based on the medium.
The different medium that can be used are Light, Sound and Radio Frequency.
In all the mediums the common technique is as follows.
You have a source or transmitter and a sink or receiver.
The transmitter transmits the pattern and it hits the object and reflects.
The reflected source is detected and received by receiver.
Now the time taken for the source to make a round trip is measured and by using the speed of the medium it is derived.
Now lets get in to some detail about the mediums Light, Sound and RF.
The light based distance sensor can be achieved using Infrared distance sensor and Laser sensor.
The Radio based distance measurement is done using Radar sensor technique.

The Sound based technique is done using Infrasonic and Ultrasonic sensor

The key difference in all the three is that the Ultrasonic cannot work on Vacuum

Infrared cannot work at high temperature.

Today we are going to see how to measure the distance using Ultrasonic sensor

An Ultrasonic sensor is a device that measures the distance of an object using ultrasonic sound waves.

It is also called Ultrasonic transducer

Sound waves.
The sound wave is classified in to InfraSound (20 Hz down to 0.1 Hz ), Acoustic sound and Ultrasonic waves.  Here the Infrasound and Ultrasonic are not audible to human ears.
Interestingly Infrasound can be heard by Elephant and we all know that Bats use ultrasonic waves for navigation.
It is not only Bats but also Cats, Dogs, Dolphins, Mice even Mosquito can hear ultrasonic sound.
There are many devices which use ultrasonic waves to control them e.g Dog whistle.

Although the distance measurement can be achieved by all Infra,  Acoustic,  Ultrasonic

the audible frequency will be loud and can be disturbed by noise.
Ultrasound operate in frequencies from 20 kHz up to several gigahertz.
They are used in many fields and it can be used detect objects and measure distances.
Hardware required:.

Banggood  Amazon UK Amazon  US Amazon Germany Ultrasonic sensor overview

Now that we have seen some theory lets get started with our project.

The Ultrasonic sensor module that we are using is HC-SR04

There are four pins in the module Vcc, Gnd, Trigger and Echo.
This module operates at 5 volt with a consumption of 15 mA current.  It can measure the distance effectively starting from 2 cm to 400 cm (4 Meter).  The module works as follows if you send a supply a short 10uS pulse to the trigger input to start the ranging, then the module will send out an 8 cycle burst of ultrasound at 40 kHz.
This 8 burst pattern hits the object and reflects back.
Now once the 8 burst pattern is sent, the Echo pin is set  high (i.e 5 V ) and when the signal reflects and comeback the Echo pin is set  low (0 V).
This time duration for which the Echo pin stays high is the time taken for ultrasonic wave to travel and comeback, yes the round trip.
Now you know the time taken for the Ultrasonic wave to make a round trip around the object.

We can now derive the distance if we know how fast the Ultrasonic wave travel

The Ultrasonic wave is a sound wave

and the speed of sound is  343 metres per second.  If TimeElapsed is the time the Echo pin was high.
Then the formula looke like as shown below.
It is divided by two since it round trip.
distance = (TimeElapsed * 34300 ) / 2 Now we know how the module works and the pinout details lets start connecting the Ultrasonic sensor with Raspberry Pi.  Like mentioned earlier the operating voltage of the module is 5V.  The input pin on the Raspberry Pi GPIO is only 3.3V tolerant.
Sending a 5V signal into 3.3V input port could damage the GPIO pins.
So we need to solve this problem.
We have two solutions one is to use a logic level converter and other is to use a voltage divider.
The logic level convert is useful if you want to pass the information from both the sides, though it will work in this case it is not required as the Echo pin is just controlled by the HC-SR04 module and Raspberry Pi will only listen for the changes.
So we should use the voltage divider to bring the voltage under the 3.3v.
Voltage Divider.
The above picture is an example of a voltage divider. A voltage divider is a simple circuit which turns a large voltage into a smaller one.
The input voltage is connected to  two resistors in series.
Here I fixed the R1 to be 1K ohms resistor and used this online voltage divider calculator to get the value of R2.
It shows that its 1.9 which is close to 2K so I used a 2K resistor.
Note: If you supply 3V to the module, it would operate in 3V and it sounds like a great idea.
But It seems like the ultrasonic sensor module does not work properly at 3V3.

Ultrasonic sensor with Raspberry PI

Now with this knowledge we can start the connection.
We need to connect  the pins in the following order.
Vcc = 5V Gnd = Gnd Trigger = Pin 23 Echo (via voltage divider) = Pin 24 Schematics.
The schematics that I am used is shown below.
Now lets get to the software part.
The ultrasonic modules operates on GPIO level and it requires no addition software to be installed.
Everything will work out of the box with python as well.
Here I have created a python script
You can log in to the Raspberry Pi via serial or SSH interface and run the script as follows $ python Output:.
The output can be seen in the terinal console or putty where you run the python code, like shown below.
Here in the the sensor was sitting on the table and pointing to a wall and that distance is approximately 300 CM.
Measured Distance = 302.8 cm Measured Distance = 303.1 cm Measured Distance = 303.5 cm Measured Distance = 303.2 cm Measured Distance = 300.9 cm Measured Distance = 304.0 cm Measured Distance = 302.1 cm Measured Distance = 301.9 cm Measured Distance = 301.4 cm Measured Distance = 303.3 cm Measured Distance = 301.9 cm Measured Distance = 303.0 cm Explanation.
import RPi.
GPIO as GPIO import time GPIO.setmode(GPIO.
BCM) The first two are the import operation, to get the required library for using it in project.
The setmode GPIO.
BCM option means that the pinumber we are using in the script refers to  “Broadcom SOC channel” number.
GPIO_TRIGGER = 23 GPIO_ECHO = 24 The pin number 23 is defined as trigger pin and 23 as Echo pin.
IN) The trigger pin which sends the 10uS pulse to the HC-SR04 module is set as output and the echo pin which sends the signal from module to Pi as input.
def distance():      GPIO.output(GPIO_TRIGGER, True)      time.sleep(0.00001)      GPIO.output(GPIO_TRIGGER, False) The function distance, sets the trigger go high wait for a micro second and set the pin to low.
This is tell the module to send the 8 burst pattern using the ultrasonic transducer.
StartTime = time.time()      StopTime = time.time()      while GPIO.input(GPIO_ECHO) == 0:           StartTime = time.time()      while GPIO.input(GPIO_ECHO) == 1:           StopTime = time.time() Firstly you store the current time in the StartTime  and StopTime variables, Now you wait for the Echo pin to go high and until that read the time and store it in StartTime.
And same way after it goes past that block you wait for it to go low and until then read the time and store it in StopTime.
TimeElapsed = StopTime – StartTime distance = (TimeElapsed * 34300) / 2 return distance Now you have the time when the echo pin went high and the time it went low.
You can find the elapsed time by doing subtraction   StopTime – StartTime and store it in TimeElapsed.
You can calculate the distance by using the time taken by sound wave multiplied by speed of light and divide it by 2 in order to get the distance of the oneway.
Interfacing with OLED Display:.
Now we are done with the basic interfacing, to make this application independant of the putty or console, we will interface this with the OLED display and display the distance there.
I have a tutorial on how to interface OLED display with Raspberry Pi.
The connection looks like shown below Connection:.
Apart from the below line which prints to the console.
print (“ Measured Distance = %.1f cm“ % dist) The additional line draw.text((10 , 40 ), “ Distance = %.1f cm“ % dist, fill = “ white“ ) prints the distances information to the OLED Display.  As mentioned earlier refer to my tutorial on how to setup OLED with Raspberry Pi for more details.
Now having extended the code to display in OLED display.
The next step is to do some application oriented projects.

Some ideas are Taking a photo when you come closer to the Ultrasonic sensor

Or Ultrasonic vehicle parking system

I will provide some basics gist of the latter one here Ultrasonic vehicle parking system: While you ever you reverse a car and when it nearing an object may it be car or a wall t it generates a tone and the frequency increases as you go closer to the object.
This can be implemented in Raspberry Pi.
Below is the example code.
It works using Pyaudio and you need to install a package before running it.
sudo apt-get install python-pyaudio Code:.
I think this covers up the basic usage of ultrasonic sensor.
If you have any comments or feedback please use the comments section below.

Les joueurs doivent se répartir en binômes

La crevasse.
La crevasse.
La crevasse.
La crevasse Issu d’un article de Guillaume Ehret La crevasse est un jeu mis au point par Olivier Soudieux, conférencier et aventurier de l’extrème.
Je vous laisse visiter son site web (

Je l’ai découvert cette année aux agiles game France 2013

Guillaume Ehret La crevasse : Objectif du jeu

Ce jeu permet d’aborder différents aspects du travail en équipe la confiance : confiance en soi, en l’autre, en la technique….
l’apprentissage : s’entraîner permet de s’améliorer, voir d’autres personnes franchir un palier montre que le chemin est réalisable.
Les joueurs doivent se répartir en binômes.
Il n’y a pas de nombre minimum ou maximum de participants.
Pour pouvoir jouer vous n’avez besoin que d’un rouleau de gros scotch (le scotch de protection peinture est idéal).
Dérouler le scotch sur le sol pour faire deux lignes séparées d’un peu moins de 2 m comme sur le schéma ci dessous (le scotch est représenté par les lignes jaunes).
Tout ce qui sera entre les deux morceaux de scotch représente le vide (zone grise sur le schéma).
Au fur et à mesure des itérations, .

Les deux lignes s’écarteront de plus en plus Déroulement du Serious Games

La première itération.
Le principe est d’avancer à deux le long d’une crevasse sans tomber dedans, tout en restant en contact permanent.
Les binômes doivent toujours avoir les mains qui se touchent (voir image ci dessous) sans avoir les doigts liés.
La zone grisée entre les deux lignes correspond à l’intérieur de la crevasse.
Si l’une des deux personnes met le pied à l’intérieur, l’issue est fatale et le binôme est englouti dans la crevasse.
Comme nous ne sommes pas en milieu naturel et que nous sommes magnanimes le binôme peut refaire un essai en repartant du point de départ Les binômes s’enchaînent et à la fin de cette première itération le facilitateur fait un tour des différentes personnes afin de savoir ce qu’elles ont ressenti.
Vous pouvez les faire réfléchir sur les facteurs qui peuvent les aider à réussir confiance : avoir de la confiance en soi et en son partenaire.
Sans confiance il n’y a pas d’engagement.
communication : se déplacer le long de la crevasse demande de la synchronisation et la mise en place d’une stratégie.
Pour pouvoir réaliser cette traversée chaque binôme doit se reposer totalement sur son partenaire.
Deuxième itération.
De chaque côté de la crevasse vous pouvez maintenant rajouter des marqueurs d’extensions avec 3 niveaux +, ++, +++ Les binômes se concertent et doivent s’engager sur un objectif à réaliser en leur rappelant qu’en situation réelle une chute est mortelle….
Chaque binôme doit annoncer la distance maximale qu’il pense être capable d’atteindre en écrivant son objectif sur un post-it que l’on expose clairement au tableau.
Si l’on fait le parallèle avec le monde professionnel les participants sont devant un problème technique ou une situation difficile.
Ils doivent résoudre cette problématique en fixant des objectifs réalisables.
La crevasse est agrandie Les différents groupes tentent de réaliser leur objectif et après une dizaine de minutes vous pouvez faire un nouveau débriefing.
Demandez aux différentes personnes ce qu’elles ont ressenties devant cette situation plus difficile.
Troisième itération.
Vous pouvez montrer l’intérêt de l’introduction d’un coach, d’un expert technique devant un problème qui parait insurmontable.
Donnez des conseils sur la bonne position à prendre.
Il faut vraiment que chaque personne repose de tout son poids sur son binôme.
coach-agile-innovation-game coach-agile-serious-game-2 Coach agile et agile playground by Archriss Les binômes peuvent s’entraîner auparavant contre un mur.
L’entrainement, la formation à de nouvelles techniques permettent de s’améliorer.
Vous pouvez aussi faire un parallèle avec la même situation sur un glacier en condition réelle.
Deux personnes sensées n’accompliraient pas ces acrobaties sans être sûres de leurs capacités, de leur entraînement.
Devant une vraie crevasse on a besoin de se sécuriser.
C’est un peu la même chose quand on se retrouve devant une demande d’évolution d’une application.
On est beaucoup plus serein si la couverture du code par les tests unitaires est importante.
Vous pouvez encore agrandir la crevasse et faire jouer les participants avant de conclure.

La crevasse : Retour d’expérience

En conclusion vous devez amener les participants à prendre conscience que la confiance, l’apprentissage, la communication permettent d’accomplir des objectifs qui peuvent paraître au départ irréalisables.
Devant un problème technique d’importance l’intervention d’un expert technique peut permettre de débloquer une situation ou de former les personnes d’une équipe.
