1.22 UART Echo Interrupt
This example application demonstrates how to use the UART peripheral to transfer a block of data in a non-blocking manner.
Description
This example shows the read and write operation over a UART in a non-blocking manner. The peripheral interrupt is used to manage the transfer. It receives 10 characters from the terminal window and echoes them back.
