How Can I receive the data through the UART in the STM32H745I?

I am using the STM board as STM32H745 controller . I taken One example program and I am able to transmit the data through the UART. But I also need to receive the data which is coming from the putty through the UART and it should be in the interrupt ...

I am trying to communicate between Bluepill and Arduino but I am not able to see the data transfer happening. The code details are as below:

STM32F103C(Bluepill) Tx:#include "stm32f103x6.h"#define USART2CLKEN (0x01UL << 17U)#define SYS_FREQ 72000000#define APB1_CLK 36000000#define UART_BAUDRATE 9600void uart2_write(int ch);void uart2_tx_init(void);int main(void){ uart2_tx_init(); while(1)...

UART using DMA communication problem

Hello,​I'm posting a question to get advice on a problem about communication with UART using DMA.​I wrote code like followings : Transmit data only when HAL_DMA_STATE is ready.   if(HAL_DMA_GetState(hdma) == HAL_DMA_STATE_READY)  HAL_UART_Transmit(hu...

Hi, I'm trying to program eMMC card with STM32U575 but the init fonction MX_SDMMC1_MMC_Init() failes in SDMMC_GetCmdResp3(SDMMC_TypeDef *SDMMCx) and return SDMMC_ERROR_CMD_RSP_TIMEOUT. Any idea?

i want to make my STM32 board as server and create GET/POST request to Erp using Ethernet present on the board. Can someone send me an example. thnx :)

i am trying to interfacing tsc2046 with stm32 using SPI communication, when i used NSS hardware at that time MOSI line continuously high & signal getting busy & code stuck.(when i used NSS software its working ok)

Looking to make a microtonal music keyboard. I would like to find a STM32 lay out for a standard, midi, with velocity sensing keys (timing between two contacts per key) keyboard and with the C program that I can use as a guide to modify for my use.

Any Algorithm for scanning, timing velocity, and or to midi would help. I could do the matric lay out. I do not want to reinvent the Wheel if posable.Thank you, ƒg.

About starting and stopping a timer by an encoder timer

Incremental encoders are known to have problems for speed measurement at low speeds. For this, period measurement at low speeds is recommended.The following statement is taken from RM0440 page 1158. What I want to do here is to start another timer in...
