Greetings, I am using a Discovery Kit (B-U585I-IOT02A) and I want to use the LPTIM1 to wait 5 seconds (counting x ticks), at the end of the 5 seconds enter in a Callback to do something and then restart the counter again.I want to use as clock source...
We are using the STM32U575RIT6 device and performed a RX/TX swap on LPUART1, ports PC0 and PC1. When we enabled the Swap TX is properly transmitting out of PC0. But we are unable to read anything on the new RX pin PC1. Other than enabling the pin swa...
Hello colleagues,Hope you may help me in one issue I'm facing w/. What I have in hands:STM32F407 discovery kitWaveShare LAN8720 ETH board is connected to discoverySTM32CubeIDE. Version: 1.18.1. Build: 24813_20250409_2138 (UTC) Simple LWIP projectint ...
Hello,With freertos cmsis_os2 osTimerStop() returns osErrorResource despite timer is running and trigs the callback after the correct time.Is there a known bug?How a timer returning pdFALSE at test xTimerIsTimerActive (hTimer) can trig a callback???H...
Good Day,Recently I started working with a new MCU (STM32L152). I ported some UART code to handle received data from a different MCU, which worked fine. But as soon as I started testing edge cases I saw some weird things happen. I am using the DMA on...
Hi,I am implementing RS-485 communication on the STM32G491. Based on available references, I’m currently using a custom GPIO pin for the DE (Driver Enable) signal, since the default USART1_DE pin is already allocated for another function. In the RS-4...
Two of my MCUs are halting in same problem after running for about a year. There have not been many writes/cycles as I have a erase cycle counter which shows 27 so its not wear out problem. The EE_Init function gets stuck at step 4 and returns with ...

Our product requires FIPS certification, and the chip is stm32u595. I found that the stm32 cortex-m33 core already has a library certified by the CAVP algorithm, but the version of the STM32CubeExpansion_Crypto-V4.2.0 library does not match the certi...
I want to write data to an external flash (w25q128 with SPI) by sending a hex file from a PC to the STM32 over UART using tools such as Realterm or a python scriptI have seen examples using the external loader with STM32CubeProgrammer, but I want to ...
