There are some things you need to learn about setting up an assembly language project in MPLABX that Microchip has not document in enough detail yet. If you can please get a copy of the entire MPLABX project from my git repository.

To help I have crafted a PIC16F84A example project you can find here. Microchip has made it very to hard to develop 8-bit assembly language applications using the latest release of MPLABX v5.40. I just created a new assembly file ( FooFile.asm) with three lines of instruction - org, clrw and end. Why didn't my building process (failed or successful) generate the list file like everyone else.The assembly was built successfully, but I can't find anywhere for the listing file (not one *.lst file was found searching through all directories).Īs soon as I add any instruction before end, the building process failed as shown in Figure. I then tested building an assembly file with one single line of comment and one end instruction. But I kept getting obscure error messages even from building the simplest possible assembly lines.Īs shown in figure, I should have the MPLabX IDE installed properly along with integration of XC8 (which seems to package with it the pic-as assembly compiler or another name for the MPASM assembler - after I struggled for hours asking and searching why a I need a C compiler for MPASM code until I realized they were bundled).

Without connecting any hardware, simulator or debugger, I simply want to build an object code file and generate a listing file from an assembly file - just to check if the IDE works. I just started learning assembly coding in MPLabX IDE 5.4.
