PIC10F200 - DS command error

[Bruno8124]

Hi,
I am learning PIC microcontrollers from tutorials on CircuitBread for PIC10F200. Recently I wanted to simulate design in MPLAB X IDE 5.50 from this example: https://www.circuitbread.com/tutorials/pwm-led-dimming-part-7-microcontroller-basics-pic10f200 (at the bottom of the page are design files to download: XC8-PIC-Assembler-Creating-a-PWM-in-Assembly-Part-7-Microcontroller-Basics-PIC10F200.zip). In those tutorials variables are defined using EQU, but in MPLAB 5.50 EQU does not provide ability to view variables during debug mode. That is why I have changed EQU to DS. That is a declaration from tutorial:
i EQU 010h ;define 0x10 register as the PWM loop variable limit EQU 011h ;define 0x11 register as the PWM limit j EQU 012h ;define 0x12 register as the delay variable dir EQU 013h

That is my declaration:
i: DS 1 j: DS 1 limit: DS 1 dir: DS 1

Unfortunately i got those errors:
make[2]: *** [dist/default/production/PWM_test.production.hex] Error 1
make[1]: *** [.build-conf] Error 2
make: *** [.build-impl] Error 2

I am using pic-as 2.32. I attached main files: main.txt - from my project and main_tutorial - from tutorial project. I have changed the extensions from .s to .txt to be able to attach the files. How can I deal with those errors? Thanks in advance.

If you are using EQU you can set an address in the watch window... Then name it and watch it...

I don't remember seeing a DS in XC assembler... I have used XC asm within MPLABX but I still prefer MPASMWIN ( I use it with VSM )

I'll give it a go..

EQU does not provide ability to view variables during debug mode. That is why I have changed EQU to DS. That is a declaration from tutorial:
i EQU 010h ;define 0x10 register as the PWM loop variable limit EQU 011h ;define 0x11 register as the PWM limit j EQU 012h ;define 0x12 register as the delay variable dir EQU 013h

That is my declaration:
i: DS 1 j: DS 1 limit: DS 1 dir: DS 1

Those are not variables - the EQU is assigning a convenient name to an internal PIC register.

You CAN view registers during debug - go to Window > Target memory views > Special function registers

I thought DW DS and DT were intel assembler define's...

He is trying to go away, using pic-as 2.32, not MPASM.

I suspect that OP, has not selected pic-as in the tool chain.

And, as I suggested him in another forum, he should read the manual. Otherwise, it is going to be a long way.

If you want to be able to follow the tutorials without having to convert them to PIC-AS (sic),
download MPLABX v5.35

That's the last version that includes MPASM
