S32K and printf() implementation

markusmayer2017 — Thu, 10 Jan 2019 12:09:27 GMT

Hi!

I'm currently starting with the S32K microcontroller.

Is there a printf() implementation/example available?

I'm using also the SDK which was delivered together

with the DS. There are two different drivers for

UART available:

lpuart
flexio_uart

What is the difference between the drivers? For what

purpose they should be used?

Hi Marcus,

here is a SDK example that uses LPUART + printf():

Example S32K_printf_implementation - S32DS

In case you are interested in printf() over the jtag (semihosting) please check this thread:

printf() through OpenSDA

LPUART is common UART/LIN module whereas FlexIO module is highly configurable peripheral module which you can configure to behave like UART, I2C, I2S,1-Wire....

I'd recommend you to start with LPUART driver since it is easier to understand how it works.

Hope it helps.

Stan
