I'm using Nucleo STM32L011K4T6 kit to test different low-power features.For this, the code is executed in RAM for 10ms (GPI/Os management) then the MCU is put in stop mode with the WFI instruction, to be woken up 90ms later by the RTC (RTC wake up).T...
Hey,I am using nucleo F030R8 om window os.I connected buttons to the board and i proggramted that each push will trigger an interupt(rising and faling). However many times i can see the the unterupt callback function is triggerd twice(2 calls for on...
I am currently using an external 16-bit SRAM chip with an stm32h743 MCU Nucleo board, using FMC for memory manipulation of the external SRAM. On Table154 (NOR/PSRAM External memory address, page 806) and accompanying footnote, it is stated that the a...
Hi there,can anyone assist in understanding how to choose the correct ‘stream’ for an STM32H7 + DMA + UART setup, please ?I’m continuing work on a previous colleague’s firmware where UART1 was programmed to operate in DMA mode. This needs to change t...
