Hi @TDK , I can communicate with the I2C line after reinitialising the GPIO pin. But, I want to know why the SCL line held low and got an "I2C transfer Timed out" issue.and also want to know, why this will occur in the long run Continous communicat...

Hi,Initially, I used an HSI internal oscillator with a 24 MHz frequency to I2C.For debugging, I have changed the I2C clock Frequency to 48Mhz from the MSI oscillator source. In this case, Issue occurrence will be reduced almost. But not resolved. In ...
