Target not responding after motor starts running

Hi,I am using STM32H743VI MCU for running a BLDC motor. When I debug and run the code without connecting the motor then I can able to debug the code and I also printing some messages on the UART, its working fine. As soon as I connect the motor with ...

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.
