hello, I have a question, which library do you use actively in keil, generally low level?

STM32H747 with Low-Power SDRAM (1.8V) read/write issue

Hi Everyone: we now have a problem running STM32H747XIH6 with Low-Power SDRAM (ISSI IS42VM32160E-75BLI) when the SDRAM clock is set to 100MHz, on our customized PCBA. I'd like to check if anyone has suggestions on how to debug.■ Description of the s...

Problem using Nucleo-H723ZG dev board with custom design (NRST related)

I am attempting to use the on-board ST-LINK V3e on a Nucleo-H723ZG development board (MB1364E) to communicate with a STM32H723 on my custom board. I have found what I think is a bug or oversight when I use the MIPI10 connector (CN5) with a Tag-Connec...

STM Nucleo Boards SPI Master/Slave Communication Problem. I set up a Nucleo-F446R as Slave Full Duplex and a Nucleo-G431R as Master Full Duplex. Master Sends -- Slave gets garbage.

The Slave Code   while (1) { //Slave Section // Check If Data is about to be received Spi3_CE_State = HAL_GPIO_ReadPin(SPI3_CE_GPIO_Port, SPI3_CE_Pin); Spi3_CS_State = HAL_GPIO_ReadPin(SPI3_CS_GPIO_Port, SPI3_CS_Pin)...

Periodical data transmit configuration

Hello,I am using STM32L0 MCU and trying to write a code which would include: Periodically transmitting data1 to UART.Constantly waiting for data2 (period value) from UART. If data2 (period value) is received from UART, change value of data1 transmiss...

I am trying to use a nucleo-f746zg as a slave using SPI6, but it seems to be dropping the first bit.

Hey guys,As I said in the title, I am using SPI6 on my nucleo-f746zg board as a slave. I have it set up to interrupt when a GPIO is low and then it it tries to receive/transmit using the HAL_SPI_TransmitReceive_IT function, but it seems to always int...

Rotary encoder interrupt per rotation

Hi all.I have a rotary encoder which generates 512 ticks per rotation and I would like to generate a single interrupt once the rotary encoder has done a full turn (512 ticks). What would be the best approach? I'm currently looking to see if the STM32...

PDM 2 PCM help

Hi, I am trying to interface a PDM mems microphone to my STM32 NUCLEO using some example code I found https://github.com/YetAnotherElectronicsChannel/STM32_PDM_Microphone.The issue I am having is this code and other things I have read online show the...
