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...

Hello to everybody,I have the NUCLEO-F303K8 and I'm trying to use an external power supply (+5V).As it is described in the reference manual MB1180, section 6.4.2, the external 5V needs to be connected to the +5V connector (pin 4 of CN4).However, by d...
Hi everyone,I have to port one proyect from a STM32F4 to a STM32H743. In this project it is important to use the SPI through DMA, so after reading a bit about the DMA-Cache issue in this microcontroller i decided to disable the D-Cache in order to ma...
Hello,I'm using STM32H753-Eval2 board wherein MT28EW128ABA1LPC-0SIT NOR flash is connected over parallel interface(FMC mode). I want to keep some part of application code into this parallel flash, I've referred one application note from Keil which wo...
Dear all,I am working on a project with an L081KZ and want to count pulses with a frequency higher than the clock. In the post here (community.st.com/s/question/0D53W00001EyzG5SAJ/) I thankfully got the tip to use the LPTIM as it has an asynchronous ...
