[xpcc-dev] UART HAL

Hi,

I was wondering why we have the UART HAL layer for the STM32? What does it add apart from making the UART classes more complex?

Background: Two days ago I did a small evening project to build a DMX512 light controller. In order to do that I needed a UART with two stopbits. As it was intended to be done fast, I copied the Usart1 class and was annoyed to have to figure out what class does what and to have to implement my changes in both classes.

Cheers, Fabian
