Sample Assembly Code for ChipKit uC32

[Gary Armstrong]

I have purchased a uC32 Chipkit (with a Pic32MX340F512H). I have a PicKit3 for development. I was provided a blink.c example which I now have running. Can anyone provide an assembly language example? I am running MPLAB X IDE.

Hi Gary,

 

All of the example projects that Digilent has for the uC32 can be found on the wiki page here: https://reference.digilentinc.com/chipkit_uc32:chipkit_uc32

Unfortunately, we don't have any assembly code projects for the uC32, you might be able to find something in the chipKIT forums though.

Hi, I guess that is the same question you asked in this post. https://forum.digilentinc.com/topic/909-uc32-chipkit/

Try this one as simple as possible, this will not even blink, but will only switch the LED on
