Overview

Uartadvanced demonstrates how to use the LPUART driver in very custom way including details like configuring interrupts and DMA channels. There are lpuart/lpuartN packages that provide ready to use drivers configured in non-DMA mode. They are sufficient for most typical applications.

This example shows how to setup a DMA enabled driver. In practice, using DMA with small 64-character Rx buffer, small portions of Tx data and slow 115200 speed is rather overkill, mainly because of the required cache maintenance operations.
