    Hi Carmine,

    What is the best way to debug I2C com?

    I ran into lots of troubles because if I debugged step by step then I ran out of I2C timing and get HAL_ERROR.

    Is it possible to debug I2C step by step?

    Thanks 😉

    Hi Oliver,
    Unfortunately the only reliable way to debug digital communications like I2C or SPI is by using an external logic analyzer. Nowadays exist a lot of good and cheap alternatives on the market. Give a look to Zeroplus products.

    Hi Carmine,

    Thanks I did not know this one.
    I was looking at OpenBench LogicSniffer @50EUR but it is a nice comparison and Zeroplus has a lot of protocol available.

    Thanks again
