Hi,I am using STM32H753ZI nucleo board, developing with Keil IDE. I am using UART RX and TX DMA. I want to check if there is a possibility of corruption of UART data while transmitting with DMA Tx.The sending device will send 8-byte defined command t...
I am currently working with the STM32H7S7I8T6 microcontroller and have selected IS42S16400N-7TL as the external SDRAM.I would like to interface both SDRAM and an LTDC display with this MCU. However, I’m facing issues because some of the required pins...
HiI got a new STM32F407VGT6 Dicovery board which is quite awesome. I have been playing with it and now I want to print stuff to a terminal via Serial. I looked up some tutotials and there they simply use the on board STLink becasue USART pins are con...
Hi, I am facing an issue on STM32F469 where UART is not initialized with DMA properly if I dont add some delay around 300ms as show in my initialization. /* Reset of all peripherals, Initializes the Flash interface and the Systick. */ HAL_Init(); ...
STM32L432KC Nucleo GPIOA resets to 0xABFF FFEF instead of 0xABFF FFFFI can't write 0 to $4800 0000 [GPIOA_MODER]Ports B and C behave as expected: the correct reset values and it is possible to write 0x0000 0000 to B and C.How can I resolve this?Or ha...
on H743 board (DevEboard) I2S1 (master 16b 44k1) -> ES9038 DAC (I2S slave) : DAC playing music fine, ok. now switching DAC to I2S master , H743 to slave transmitter mode : no data / silence.test with DSO : pin PA7 (SDO) is tri state now! thats WRONG ...
Hello community ,I am newby trying to do a small project with STM nucleoh563zi and stumble upon following brickwall .I need to interface an Incremental encoder that produces 1000pulses per rotation and simply print it to com port and i searched a...
OK, this is perhaps a fairly stupid question but I do not get it.I have an analogue voltage in range -5V..+5V and wantto measure it with the ADC of an STM32F446. The ADC-input works in range 0..3.3V.I have the feeling I can do that with a simple, res...
I'm working on recording audio synchronously using multiple I2S microphones connected to different SAI subblocks on an STM32H7. I’m trying to synchronize all four SAI subblocks to ensure aligned multi-channel audio capture.So far, I've successfully c...
IS ANY BODY HELP ME IN THE OTA OF THE STM32U575 USING THE ESP321. HOW TO SETUP THE SYSTEM BOOTLOADER TO RECEIVE THE FIRMWARE (.BIN FILE) VIA UART AND HOW TO SELECT WHICH UART TO USE FOR UPLOAD , THERE ARE MORE UART WHICH SUPPORT THE UART FLASHING HOW...
