Examples about USART serial communication (TX and RX simultaneously) with FreeRTOS. I am trying to adapt the examples in documentation (e.g. P-NUCLEO-WB55.Nucleo\Examples\UART\UART_HyperTerminal_DMA) to use them into FreeRTOS task but it is not working.
My purpose is to be able to send and receive serial communications using USART in asynchronous mode.When I try to adapt these kind of examples using UART_DMA in FreeRTOS, are not working. I copied the configuration regarding IRQs, DMA and USART inici...
