Onboard LPUART_1 communication on TWR-KE18F (MKE18F512VLL16).

[rohitchudasama]

I want to use onboard LPUART_1 on TWR-KE18F (MKE18F512VLL16). I already connected one UART device to LPUART_1 (pin # 55,56,57,58). How to write a code in KDS to Transmit and Receive  data stream ?? what type of configuration i have to do ??

Thanks.

Hello robin,

I change lines according to your info but still its not working.

I can build and debug after changes but unable to communicate. I mean, unable to see startup message.

Is there any changes in hardware i have to do ?

Thanks

Sorry for the late reply.

With the default jump setting described in TWRKE18FQSG. No needs to change any hardware.
You are unable to see startup message at OpenSDA Virtual Serial Port due to the LPUART1 is only available at J15A of ELEVATOR CONNECTOR.

I attach that lpuart interrupt project here. So that you can test it.

Best Regards,

Robin
