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 ...
Hello I am trying to learn I2C communication between 2 STM32F103C8 MCUs. MCU1 acts as the master and MCU2 acts as the slave. I am using CubeMX to configure the settings however I could not establish a link between the 2 MCUs. What I wanted to happe...
