Title: Kinetis UART / LPUART Referencing
Post by: mark on February 22, 2015, 03:20:34 AM

Hi All

 Kinetis devices originally contained a number of UARTs, with up to 6 available in some parts - such as the K60. More recently newer parts started appearing with LPUARTs (Low Power UARTs), for example the KL03 with a single LPUART. However some parts can also include both types, such as the KL43 with two LPUARTs plus a single UART, or the K22 with 3 UARTs and a single LPUART.

UARTs and LPUARTs have various differences and the question that arises when using a driver interface is how can they be handled in a generic manner so that appliation code is compatible as well as how are the channels numbered in the µTasker interface?
