Hi all,I am using STM32L431 and the device is not waking up from STOP mode with an RTC alarm interrupt. Can somebody pinpoint where my issues are?My configurations in the code configurator:I am enabling the crystal oscillator, enabling the calendar, ...

Hello, can you please provide a MTBF or a FIT value for the VN808TR-E and STM32H743ZIT6 ? Please, let me know. Best regards,

How to transmit hex data over spi?

I want to transfer binary data (not character) without having to worry about character conversion, so directly:uint8_t data = 0xBF;HAL_SPI_Transmit(&spi1handle, (uint8_t *) data, 1, 1000);But I get something else at the receive end, specifically I ge...

EXTI Interrupt Handler throwing HardFault for one MCU, but not for other MCU

I have two custom boards with one STM32F746 each. Both MCUs run identical code (in different projects with potentially different configuration).One MCU runs as expected, but the other MCU throws a HardFault as soon as MX_NVIC_Init() enables EXTI int...

ISM43362 WIFI Module on B-L475E-IOT01A

I connect with the module to an Access Point and get IP. Now I have some devices connected to the same Access Point. I want to receive UDP packets from the devices.What should I do? I can connect only with TCPif (WIFI_StartServer(SOCKET, WIFI_TCP_PRO...

Hello! What is the difference between output compare and output compare no output in Cube IDE? Can I use output compare no output to trigger ADC?

Potential bug with SPI3/I2S3 for STM32H753ZI

Hi guys!I believe I found a bug with the SPI/I2S peripheral.The initial problem started here: https://electronics.stackexchange.com/questions/571749/function-pointers-causing-unexpected-behaviour-within-stm32h753zi-microcontrolle?noredirect=1#comment...

I set the MCU STM32F103C8 to 72 MHz (8 MHz external oscillator). However, the function does not give exactly 1 ms of time, but a value approximately 4 times larger. Any suggestion?
