Hi, I'm trying to use HAL_UART_Receive_IT with a fixed size buffer, but only the first element changes its value.I'm using CubeMX over NUCLEO-STM32F446REThe only things I do:main.c I declare the buffer like this:uint8_t rx_buffer[5];The UART initiliz...

Hi, I'm new with stm32 and I want to get a simple 1Hz square wave in a NUCLEO-F446RE using CubeMX for the initial config. The code is so simple that I can't figure out where the problem is.I just do: while (1) { HAL_GPIO_TogglePin(GPIOA, GPIO_...
