HRTIM periodic calibration

I use HSI16 as my clock base which goes through a PLL and then into the HRTIM.Let's say that I adjust HSI16 periodically (every ~10 milliseconds) to track an external high precision clock.Is enabling the DLL calibration (HRTIM_DLLCR:CALEN, CALTRE) en...

hello. i am working on a project using two stm32g431rb nucleo boards. i need to make a connection between these mcu's so i choose I2C as the connection protocol.

the problem is when the master micro wants to tell the slave to send some data, after a random time the i2c connection disrupts and i will get HAL_ERROR Message. i wrote the below codes for master and slave:Master code:  while (1) {  /* USER CODE END...
