STM32H7 Dual Core shared memory access

Hello!i am currently working with the dual core H7 trying to create some kind of communication systems between the cores. i have read and tried to implement what was suggested in the following thread: Best/easiest way to share data between cores in S...

Enable/Disable interrupt in sleep mode

Hi all,I work with STM32F413 and CMSIS os.I have a problem when I put the CPU in sleep mode by HAL_PWR_EnterSTOPMode.In the os_idle_demon I need to disable one external interrupt, do some job and enable again the interrupt and so on.My problem is tha...

Can't seem to get Shawn Hymel's custom "printf" library working on my C++ project

Hi everyone,I have a noob question regarding using "printf" on STM32F4 boards. I found a library made by Shawn Hymel which will let me use the function "printf" to the serial port:https://shawnhymel.com/1873/how-to-use-printf-on-stm32/?unapproved=634...

CONFUSION IN STM32F302R8 MASTER TRANSFER DATA DIAGRAM

Im having a confusion on my diagram about the EV2. Why does the EV2 happens during the transfer of data1? and it does not happen during transfer of data2? Or could someone explain about my master transfer diagram? the MCU model is STM32F302R8

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 ...
