Hello,I'm trying to get multi-buffer DMA on ADC working. I modified `HAL_ADC_Start_DMA` function to use `HAL_DMAEx_MultiBufferStart_IT`instead of `HAL_DMA_Start_IT.But for some reason, M0 Completion Callback is executed multiple times before switchin...
Rev. 5 of those RMs introduced dual-bank devices. According to "3.3.1 FLASH memory organization" the page numbers in bank 2 start at 256, which seems to be very odd as the PNB field in FLASH_CR has 10 bits, so one would expect 1024 instead.
Can Anyone Suggest me the External SDRAM Supported Part For STM32L496ZG ?
Hi. There is a task of displaying the menu, data input-output, editing from the terminal. I use stm32h743 communication via com port. Looked closely at the "ncurses" library, the problem with porting it to the project. I have no operating system. The...
MCU: STM32F072, clock: 48MUART BR: 115200, clock: 48Mapplication: receive 20 bytes per secondissue: overrun happens sometimes, maybe after 3 hours or 1 day.I think the clock is fast enough to handle the slow application, but overrun happens sometimes...
I'm using HAL_UART_Receive to receive 8 bytes from a Nextion screen. The baurate is 9600, so the response takes ~10ms.If I set the timeout around 50ms, the response is not read properly. If I increase the timeout to 300ms, then all works fine.I don't...
Hello,I am using STM32F469 with an external SDRAM (Alliance AS4C16M16MSA-6BIN) through FMC bus. Both STM32F469 and AS4C16M16MSA-6BIN run at 1.8V. The FMC bus is configured with 13 address pins and 16 data pins as follows: hsdram1.Instance = FMC_SDRAM...

Hello everybody:i'm trying to implement modbus function on mcu(stm32F4)my structure as followingi receive data from usart6 by HAL_UART_Receive_DMA function(circular mode)it's work when just only one MCU edge. but if two mcu edge (two modbus slave),...
