I’ve verified that the GY-25 is transmitting data, but my HAL_UART_RxCpltCallback is never triggered, and the rxBuffer remains empty. I am using USART2 to communicate with termite. Here is a simplified version of my code: #define RX_BUFFER_SIZE 8 uint8_t rxBuffe...

Callu8g2.firstPage(). Start a do-while loop Inside the loop-body: Draw something with the usual draw commands. Loop as long asu8g2.nextPage()returns true. Note: Always create the same picture inside the loop body. See detailshere. Example void setup(void) { u8g2.begin(); } void ...

Each project template provides empty main loop function and can be used as a starting point to get familiar with project settings for STM32Cube. Its features are the following: It contains the sources of HAL, CMSIS and BSP drivers which are the minimal components to develop a code on a ...
#if DT_HAS_COMPAT_STATUS_OKAY(st_stm32_spi_fifo) /* Flush RX buffer */ while (ll_func_rx_is_not_empty(spi)) { (void) LL_SPI_ReceiveData8(spi); } #endif but it doesn't work: ll_func_rx_is_not_empty(spi) is always false. 3- why do we skip test "every 4" when DMA ...
