Hi everybody, I have continued with my code (on the base of a code sent to me by ghp) and as I am still struggling a lot I am looking for someone to help me to build, debug, improve... what is already done : http://getwebb.org/v/wvOAPj5B I am especially wondering why when I run the code the print li...

Hi everybody, I have connected everything as suggested by ghp. However when I measure the total resistances with a multimeter on each channel I do not have the exact values (+/-5 Ohms)... Anyway I am going to try with this. Now I would like to test the ADC ADS1118. I found a code on the github page ...

Hi Gerhard, Thank you again for your technical and accurate answer. However, I am not sure to understand everything (especially for the PGA..) so I quickly drew a scheme. We do not have IF300A or IF300B interface boards on our TPG 300 we juste have a PI3000D and a Cold Cathod board... http://s4.post...

Hi everybody, I would like to check with you my electrical drawing as I am not very good with this matter.... In order to convert Analog Data from a plug-in module for pressure gauges (TPG 300 with 2 Pirani and 1 Cold Cathode gauges) into Ditigal Data to be read and used in a program on a Raspberry ...

Hi everybody, Can someone help me regarding my issues with multitasking and FSM, I really struggle with these notions in Python. I do not have the programming skills to implement this and lost a lot of time and hairs trying things that doesn't work... http://getwebb.org/v/rMyV3xUT I would like to Sk...

No sorry the pins are the same on the screen than the one of the link but the GPIOs I chose on the Raspberry Pi are not the same than what it is specified...
I think I try to take too much power from the 5V pins supply (but I am a bit surprised) I will try to redirect few indicators to the 3.3V...

My screen shut down my Raspi when I plug the 5 V power on the pin number 2 refering to the datasheet, all the other pins of the screen can be plug without turning off the Raspi...

Hi and thanks for your answer. Raspberry Pi 2 B This LCD screen : http://www.distrelec.ch/en/dot-matrix-oled-display-mm-16-electronic-assembly-ea-w162-x3lw/p/11026976?q=lcd&page=5&origPos=112&origPageSize=25&simi=99.77 4 bits parallel : http://www.raspberrypi-spy.co.uk/2012/07/16x2-lcd-module-contro...

I am trying to add a 16*2 LCD Screen to an electronic boxe I am currently building, but when I connect the 5 V power supply to the screen my raspberry pi start to blink green and then turn off... I tried the screen independtly of the boxe in the past it worked... My raspberry Pi supply a ULN28001a f...

Hi everybody and thank you for your answers, As I wrote in my first post I am totally new with Python and Raspberry Pi (and also not very good with coding techniques), so there are several programming concepts you mentioned with which I am totally ignorant (cron jobs, queues...) I got a look at cron...

Hi everybody, I am working on my first project with Raspberry Pi and Python for more than 2 months now and I really struggle with my python code. The hardware part of the project is almost operative but the software part... I have recently discovered threads and FSM and I am not sure about how to st...

Hi everybody, Does anyone knows if a python library for the ADC ADS1118 SPI (16 bits from TI) exists ? I managed to find a beautiful library for a similar ADC (the adafruit library written for the ADC ADS1115 I2C (16 bits TI)) but the I2C protocol is used for this one and not the SPI. https://github...

Bonjour tout le monde, Je suis nouveau sur le forum, dèbutant avec Raspberry Pi et je ne m'y connais pas trop en électronique.... :o Actuellement en stage je dois continuer un projet commencé par un prècèdent stagiaire (boitier electrique pour contrôle de chambre à vide). Dans un premier temps je do...
