Hi community, I am trying to use a Nucleo-L053R8 board to send data over USB without much success. The purpose of my project is simply to test the USB communication by sending string over USB Port as a first step before sending the sensor data. When ...
resolving a conflict between using Timer3 interrupt and HAL_Delay()
Hi all,Hardware - STM32L4R9 Disco with STEVAL-MK172V1 eCompassI'm stuck trying to resolve some kind of conflict I'm having with Hal_Delay. I've lowered the priority of the timer interrupt so that SysTick is a higher priority. I've tried using both th...
Resolved! Verify if it is safe to continue I2C communication after I2C transaction instead of using HAL_Delay
I made an I2C communication between STM32U585 uC to an I2C EEPROM and it worksI do the following but if I remove the HAL_Delay(10) or minimizes it to less than 10msec things are not working well, the second call I2C_Master_Transmit fails.Is there's ...
