To merge the two problems : viewtopic.php?f=35&t=3634
If no transmision on going, shorting the pin does not cause any problem.
And also if we put our sampling rate to 10sec wee don't have this issue.
It s only happening when we are sampling at 10ms

Re: Bug/Problem in I2C on STM32F401
We sample on the i2C every 10ms.
If while we are doing we put the SDA to the GND. We get stuck on loop of interuptions.
Version ChibiOS 17.6.x stable
We have already pull up resistor on the SDA and the SCL

I2C SDA on GND
Hi all,
We are using ChibiOS version 17.6
With ARM GCC as Compiler on an STM32F446
We use an external I2C device. When the GND touch the SDA we get stucked in loop of interuptions on the I2C event.

Re: Bug/Problem in I2C on STM32F401
Any news about this bug ? We are facing the same scenario. When SDA touch the GND it s locked.
