cmsis_usart_sdma_transfer

Overview

CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide range of supported microcontroller devices. The API connects microcontroller peripherals with middleware that implements for example communication stacks, file systems, or graphic user interfaces. More information and usage method please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.

The cmsis_uart_sdma_transfer example shows how to use uart cmsis driver with SDMA:

In this example, one uart instance connect to PC through uart, the board will send back all characters that PC send to the board.

Note: The example echo every 8 characters, so input 8 characters every time.
