I'm quite new to using an AVR, and haven't written Assembly Code before.
I'm trying to program an ATmega324A, by following snippets from a handful of tutorials off the internet.
I'm programming on MacOS Big Sur (Intel Chip).
Issue:
I've been trying to assemble some (frankly, unchecked) AVR Assembly code for the ATmega324A, using AVRA.
However, I'm unsure how to do this using the CLI.
I've used multiple variations of the code below, including:
Using a locally stored m324adef.inc
Writing the basic command shown in the documentation:
avra test1.asm
Specifying the Device type for the Assembler (Unsure how this works, but I've tried both "m324a" & "ATmega324A"):
```avra -D DEVICE=m324a test1.asm
Code:
; The .include directive was changed to read "m324Adef.inc", as well as removed entirely, to see if there was any difference.
.include "m324adef.inc"
.cseg
.org 0x00
main:
ldi r17, 0x01
out DDRB, r17
out PORTB, r17
Result:
Each time, the Assembler returns that it either:
Does not recognize the ATmega324A's .inc file:
m324adef.inc(47) : Error : Unknown device: ATmega324A
Does not recognize a Device type "ATmega324A" / "m324a":
Error : Found no label/variable/constant named ATmega324A
It does not know how to interpret some of the pin definitions:
test1.asm(10) : Error : Found no label/variable/constant named DDRB
test1.asm(10) : Error : I/O out of range (0 <= P <= 63)
test1.asm(11) : Error : Found no label/variable/constant named PORTB
test1.asm(11) : Error : I/O out of range (0 <= P <= 63)
I also noticed that, when running --devices, it did not list the ATmega324A processor as a supported processor. It did include the ATmega324P, and ATmega324PA processor. While skimming through the GitHub repository, however, it looked like there was support files for ATmega324A, in the "includes" folder.
Is there an obvious mistake, or step that I've forgotten?
Please let me know if I should any more detail.
