Hi Friends,

I am new to embedded programing.

I tried to develop and implement a simple task with PIC18F25K42 and PIC45K42.

Input1: Switch Output1: generally LED off and blinks if SW_ON. Actual LED status update through UART1.

Input2: Pot Output2: Periodically measures voltage and update value through UART2.


I got simulation result without any issues. But while i tried to compile to HEX, i got warnings and errors which i can't able to understand. Kindly let me know either the mistake i did or steps need to be follow for generating HEX file for implementation.

Note: HEX file successfully created without UART.

Thanks in advance Hand.

Hello,

Your program is compiling ok for me with the K42 device, please can you use the Help -> Check for updates menu to make sure you are using the latest versions of the libraries.

Thanks Benj,

I will check and update the status.

Hi Benj,
Right now compiling without any error message.

Thanks a lot.
