Re: [xpcc-dev] Error with I2C eeprom

Hi,

Which specific I2C EEPROM chip do you use?

I'm using a 24FC128, specifically chosen because the driver mentioned this family.

You can debug the SoftwareI2C driver by adapting these lines: https://github.com/roboterclubaachen/xpcc/blob/develop/src/xpcc/architecture... This will give you a reasonable debug output over serial.

Sadly, I don't have a serial output connected to a PC, but I mostly got used to it by now. I use the LCD for basic debugging, will see what I can figure out using that.

If that fails, I recommend looking at the physical bus with a logic analyzer.

I'm not sure I can get my hands on one, but if the problem persists I'll try. Antal
