LPUART driver usage

[gschelotto]

Hi,

I need to implement a simple binary communication using LPUART driver provided by MKL27 SDK v2.2.6. The example frdmkl27z_lpuart_interrupt_transfer works fine but is written to receive a fixed-size frame of 8 characters and my application have to be capable to receive a variable-size chunk of bytes.

I would like not to reinvent the wheel (again). Is there a driver example with a similar implementation to adapt it to my needs?

Thanks in advance,
gaston

Hi Gaston Schelotto ,

   In fact, SDK just give you an example, for the detail usage, it is determined by your application.

   You said  you need receive a variable-size chunk of bytes, you totally can use the UART idle function to realize.

   Our FAE has shared one technical experience about it, it is the KL26 code, but you can refer to it.

This is the code download link:

You can check the source code and refer to it.

Wish it helps you!

Have a great day,
Kerry

Hi Kerry,

Thanks. This code is useful to understand UART operation using interrupts and without SDK.
