I2C to raspberry pi temporal detection issue

€250-750 EUR

Paid on delivery
We have an implementation of a raspberry pi communicating through I2C with two PICs. After working for some time (hours, days or weeks), one of the PICs or both are no more detected by the pi. Booting the pi does not solve the problem. We need to boot the whole system so it works again. We need expert assistance in I2C and raspberry pi to solve this issue, since we need this communication to be stable through time.

I've read your problem description and I can help you with this project because I have 4+ years of experience using Python and RPI for embedded system and IOT applications. Especially I've got this I2C bus reset problem in past as well and I had managed to solve that and I quite hopeful I'll be able to solve that for your case also. Please let me know of the distro you are using currently and any other dmseg outputs etc. I would be happy to help you. Thanks.

Probably the pics are messed up or maybe the raspberry. Guess volts/levels between both are not normalized.

Hello, I am an expert in Embedded systems and experienced with the raspberry pi, I2C communication and microcontrollers including PIC and AVR. Your issue sounds like a timer overflow or similar. My process to resolve the problem would be to review your software and run simulations if necessary to determine the cause. Since rebooting the pi does not fix the problem, I would suspect the issue to be located in the PIC code. I'd be happy to work with you on resolving this problem, so please contact me via chat. Please let me know if you have any further queries. Regards

I have experience on Raspberry and microcontrollers development. I have a oscilloscope that could help to find the problem in the fault of the communication that you indicate. I proposed 20 days, because to find a bug required understand all the code before try find the bug in the code.
