How to run DAC in STM32F107VC using HAL functions?

Hello. I have written a program to run the DAC in the STM32F107VC and I have used STM32CubeMX and HAL functions. But I don't see any waveform in the DAC output (PA4 pin). I was able to run the DAC using set the DAC registers. But I don't succeed with...

I am planning to pre-program the flash memory of STM32 for production, how will the reflow oven affect the data retention of the flash memory? According to the datasheet the data retention is specified to 15 years @85°C and 1kcycles. Thanks!

Flashing a HEX file in STM32F4

Hi forum.. I developed a bootloader for flashing a hex file present in usb key. The text from the usb key is transferred via UART to another micro.. The bytes are then flashedin the flash area.. You can find the HEX file in the usb key here ..When I ...
