Configure UART in mkl27z64

Anjali — Thu, 03 Sep 2020 07:06:41 GMT

Hi,

I am new in the embedded field and ow dealing with kinetis FDRM-KL17Z dev board. I need to configure UART on it. I found some example projects and could send and receive the data from the terminal. But I do not have knowledge of handler. To integrate this UART function in my project, I have to know how to use handlers. Is there any better examples available which give more idea on this?

Regards,

Anjali

Hi,

You can download KL27z SDK from this link,https://mcuxpresso.nxp.com/en/welcome.

And there has some uart examples in package.It explain how to configure uart and how to enable the interrupt .And also shows how handler function works.

Jianyu:

Have a great day,
TIC

The open source uTasker project on GITHUB supports the KL27 with advanced options for TX and free running Rx DMA in addition to interrupt driven modes.

UART guide document: https://www.utasker.com/docs/uTasker/uTaskerUART.PDF

It allows a simulated KL27 to run under Visual Studio for full emulation of the UARTs (including their interrupt and DMA operation) so if you are learning about programming, the UART or general processor operations it makes it very easy to study and understand.
