avr-objdump outputs in lower case, it's not that. N.Winterbottom wrote: I think your avr-objdump is broken.

For PORTA, it looks very similar:Ĭould it be that this disassembly thing is broken, and it doesn't correspond to what is actually generated? (MPLAB X v5.35, "Window > Debugging > Disassembly Listing File")

Mplab xc8 instruction set manual#

and even if STS instruction uses some address pointer (I don't think the manual said anything about that though). What puzzles me is the absence of address. (Not sure what that stuff at the end is though) C:/Users/jani_/MPLABXProjects/AssemblyTest.X/main.c. The entire (redundant lines removed) disassembly file reads:Ĭ:/Users/jani_/MPLABXProjects/AssemblyTest.X/dist/default/production/AssemblyTest.X.production.elf Target device is ATmega4809 (Curiosity Nano evaluation board) and the compiler is XC8 v2.20 (unlicensed). and now even I can understand what is going on!Īpologies, I definitely should have included chip and compiler information. resulting in nonsense (exists as an issue MPLABX-3894, thank you meolsen for pointing this out). STS, as pointed out here in the helpful comments, is a 16-bit instruction that also needs a 16-bit address, which was disassembled as two 16-bit instructions. SOLVED: Turns out that the MPLAB disassembly listing cannot correctly disassemble the result. Compiler is XC8 v2.20 (unlicensed) and target device is ATmega4809 (Curiosity Nano evaluation board). I don't seem to get any smarter.Ĭould some kind person explain to me how those two instructions achieve setting the bit in PORTF.DIRSET (at 0x04A1)?Įdit: I should have included some tool information. I have REALLY tried, but no matter how many times I read the Instrution Set Manual or how much I try to google something to shine some light into this. I don't really know assembly language, and the second snippet makes no sense to me most likely just because of that. That's Read-Modify-Write pretty clearly.but then. I was reading about Read-Modify-Write and thought to look at how the assembly differs between PORTx.DIR |= PINn_bm and PORTx.DIRSET = PINn_bm. Do not attempt to program an actual PIC MCU or use the PIC kit3 programmer.I hope this is the appropriate section for my question.

Mplab xc8 instruction set code#

Include proper program commentary at the beginning of your code (header block) and individually for most lines of code.

Mplab xc8 instruction set simulator#

Use the simulator to monitor your selected output port. Repeat the above in an perpetual loop, so that the chosen output pin cycles on and off indefinitely. Program a short delay using an incrementing or decrementing loop and then turn the same pin off. Write a C program to turn on one of PORTA's pins. Having installed the software, create a new project and select the PIC18F1320.

Mplab xc8 instruction set install#

First download and install the latest version of MPLAB X (latest version is v5.45) and the XC8 compiler (latest version is v2.30) following the class PowerPoint directions. Procedure Refer to the lecture materials to complete this lab.
