Hi there,I am new with UART and want to use my own UART Functions and i found the function HAL_UART_RxCpltCallback and HAL_UART_TxCpltCallback.When are this Functions called? I found them in the documentation of stm but that didn't explain well when ...
I have tried simple code* USER CODE BEGIN 0 */uint8_t myTx[13] ="hello world\r\n";;uint8_t myRx[13] ="hello world\r\n";main();* USER CODE BEGIN 2 */HAL_UART_Receive_DMA(&huart2, myRx,13);while(){//nothing here{/* USER CODE BEGIN 4 */void HAL_UART_RxC...
Hy,I'm trying to run the DFU mode with a STM32F205. When I put boot0 to VCC and I do a reset, the DFU USB was not detected by my computer. Can someone help me ?I tried before that on the nucleo card F207ZG and this work corectly.
When USB connected with Trace ON everything is OK when Trace is OFF time to time MCU is slowing down
Hello,Checking stm32h743 eval examples (cube) of NOR, there is a wait on busy/ready signal in code:/* NOR Ready/Busy signal GPIO definitions */ #define NOR_READY_BUSY_PIN GPIO_PIN_6 #define NOR_READY_BUSY_GPIO GPIOC /** * @brief NOR BSP Wa...
Hello, I have configured the NUCLEO-STM32F746ZG to use the SDMMC interface. However, the generated code has a buffer overrun in it. I found a patch to the SDIO interface on the forum, so I applied it, and it works. Here is the patch. Please update...
Is there a HAL method that allows you to easily set a transmit DMA interrupt like "HAL_UART_Transmit_DMA(...)" but without setting the half transfer interrupt routine? Since the Tx buffer is full when this is enabled, I can expect the DMA to start tr...
Everyone, I would like to tell you. I will use the HAL library for the first time. What functions should be called in the main loop for write commands and read commands from I2C-Master? I am very happy if you can provide a sample source. I saw the so...
for SPC58NE series.I know that Ethernet uses SPI protocol with MCU, but It's helpful if there're examples
