Hi,I've been using an STM32L151 for a number of years...long enough ago that the firmware I wrote uses the SPL, not HAL, and I'm really not interested in re-writing the firmware!My problem is that a new I2c device I am connecting requires a RESTART b...

I have solved my problem, not exactly by following the chart to the code specified, but the code and chart did help me to better understand how the peripherals work. The fix can be described in the chart, or in my code. In both cases, there is a re...

Wow! That chart is amazing! That actually makes some stuff a lot more clear! And it does look as though it probably matches the STM32L peripheral. Thank you!Also, I'm not at all surprised the code is buggy. No doubt it works for the few periphe...

Thank you. I do have the restart working, but now the stop at the end of the read is intermittent. It seems to depend on what came before on the bus. A couple things though: The example above uses DMA. The driver I am working on (written by some...

Thanks. I'll double check. Yes, we are already doing the start on the read that follows the write. I'm having trouble with NOT enabling stop after the first write. As I say, I'll read this code more carefully to see if it can be adapted to my int...
