Resolved! Weird behavior at HAL_GPIO function. Why the microcontroller is unable to set some pins after execute HAL code assertion statement?

I was running and debugging a part of my application on a stm32F207zg microcontroller.Microcontroller is on a custom PCB that is in validation process.This part of application has to set or clear 16 gpios configured as output.If they are initialized ...

Resolved! How to make a PWM of 13.9ns pulse width with HRTIM?

Hello ST community,I use a STM32F3348 DISCO board (STM32F334C8Tx MCU) and I would like to realize a PWM with a period of 4µs (250 000 Hz) and a pulse width of 13,9ns. I tried first with the TIM1 and then with the HRTIM but in both cases I can't reduc...

Implementation of a STM32 in transparent mode to flash another UART-connected STM32. What UART configurations and timing should be setting to implement this feature in STM32 in transparent mode?

I have one Master STM32 connected over UART to a Linux MPU and also connected over another UART to a Slave STM32.My purpose is to set the Slave STM32 in bootloader and flash from the MPU the application in the Slave STM32, the Master STM32 is in the ...

HAL_FMPI2C_Mem_Read_IT() in library "stm32f4xx_hal_fmpi2c.c" claims to be "Read an amount of data in non-blocking mode with Interrupt", yet behaves as a blocking call. Where am I going wrong?

My understanding of a non-blocking function is that the function will return immediately, and it is up to you to use a callback or other method to collect the data. With FreeRTOS it's not difficult.Yet HAL_FMPI2C_Mem_Read_IT() seems to hang around an...
