I'm trying to port code from STM32L4 to STM32U5.The STM32L4 code was using the LPUART, with a baudrate of 20k, clocked with HSI but in stop2 mode the HSI was stopped, it was able to wakeup and read incoming data. This configuration was using ~10uA.I'...
I'm trying to get the ethernet initialization work. I am currently dealing with MX_ETH_Init(); failing in error handler as the software reset is not happening with the phy driver. I believe my clocks are not configured properly as per manual : As ...
Hi,I've been implementing CAN1 on NUCLEO-412ZG board. CAN bus is able to transmit and receive CAN packets. However, the problem is when board receives CAN packet from PC over CanAnalyser tool, it transmits the same packet on Tx line automatically. As...
Hi, I designed a board with uC STM32H743 that works with a 480x800 display connected through the LTDC peripheral, I don't quite know how to use the LTDC, I don't have ram for the buffer of the entire display. What I can do is fill the background with...

Hi,I am developing and exploring a register programming based SPI driver. I took my time to read the datasheet and analyze the SPI startup sequence. For testing, I am using pre-programmed SST25VF080B memory IC. I wrote a simple and low speed (less th...
Hi, My application has a bootloader, recently, I allocated a large block of memory on top of SRAM to protect the data from system resets, this causes the highest address of user stack changes, when this highest addresses of user stack are different i...
Hello all, I developed a UDP server/client with the objective to send and receive data simultaneously. The code has some problems in the way its written (e.g., unnecessary loops, variable definitions inside a loop...), but I'm only interested in solv...
