Hello,I'm working with an STM32G4 MCU and I want to listen the UART3 with interruption. I am testing with a code which changes the color of a led. The following code works fine ://main.c #include "main.h" FDCAN_HandleTypeDef hfdcan3; FDCAN_...
Hello,I have to interface the ADS7046 12-Bit, 3-MSPS, Single-Ended Input, Small-Size, Low-Power SAR ADC. Spi compatible ADC 12 bit resolution and MSPS.1.How to set its data size in spi configuration?2.In datasheet they did not give the clock polarit...
Normally I use ST-link for programming. But I can not see data in serial port on computer. I use TMS,TCK,RST pins for programming. I would like to solve this issue for my new design. Could help me please? What I need to learn exactly ?
In the MCUFInder application, I can filter on the CAN bus, but it doesn't get the MCUs having a FDCAN controller.Is there a way to get only the ones having FDCAN ?Example : if you check one CAN controller, you don't get the STM32G0B1 who has FDCAN.I ...
The MCU stops when the program reaches this line (FLASH->CR |= FLASH_CR_OBL_LAUNCH;) in the function below.The option bytes I want to write are at the moment still unchanged to the delivery state. Later they will be changed to RDP Level 1.void Option...
Hello,I want to disable the uart rx interrupt during transmitting the data like the following flow.UART Rx interrupt disable(Only uart rx interrupt)UART Data TxUART Rx interrupt enableWhich HAL Library I could use for this process?Thanks
It is not a question but info for others.STM32flash app on RPi can connect to STM32H743 on NUCLEO board (tested on SPI2).AN2606 says "Bank erase is not working on USART/SPI and I2C" but even page-by-page erase does not work so CPU cannot be programme...
Hello forum users!Created a project by example[url] https://istarik.ru/blog/stm32/159.html [/ url]Slightly corrected, so that a new frame is sent every 10 msec.The project works at (except one) any speed (100kbit - works, 500, 800 - works).Data is tr...
