Stuck on first attempt using MPLAB X (PICkit4)

Nope, $50. Or am I missing out on "special promotion to forum moderators"?

Well, there is no moderator offer.

Did you try to down load and install the later version and then auto activate it?

I do not really remember when was my upgrade that I had to pay. Then on, I just updated the compiler and it auto activated.

I was missing a pull-up on MCLR, and my soldering job was dodgey. I made a new harness, looks much nicer.

Still going nowhere in MCS+5; keep seeing HEX FILE MISSING before the command line window closes.


Managed to program using MPLAB IPE, I just don't get any blinky action on my Lab X-1.

I'm gonna set up a breadboard, got a feeling something is wonky on my Lab-X1 (either OSC setting, jumpers, or that programmer header.

Get rid of the config DEBUG_ON.
If you ever get to the point of hdw debugging that will be managed by the tool for you.

Also, when you were creating the IDE custom programmer entry, once you get to the step of setting the parameters there is no "Next" step... just "Finish"

Thanks, had already turned it off. Waiting for a reply from MeLabs forum to get the custom programmer working in MCS+5.


Kept playing with the Lab X-1 and MPLAB IPE, played with OSC, added PORT, used bits like I did in one of my programs; now the proper LED comes on, but no blinking on the Lab X-1.

#CONFIG
    __config _HS_OSC & _WDT_OFF & _WRT_OFF & _BODEN_ON & _LVP_OFF  & _CPD_OFF & _PWRTE_OFF & _DEBUG_OFF
#ENDCONFIG

DEFINE  OSC     20

ADCON1 = 7              ' A/D off, all digital

PORTD = %00000000
TRISD = %00000000

START:  PORTD = %00000001
        PAUSE   500      
        PORTD = %00000000
        GOTO    START

Finish: end

Tried using another PIC just in case, no difference.

But get this, I copied an old example of writing to the LCD and that worked, a bit wonky, but I can't get a solitary LED to blink.

You won't see a 1uS blink

START:  PORTD = 000001       
        PAUSE   500      
        PORTD = 000000
        GOTO    START

you probably meant

START:  PORTD = 000001
        PAUSE   500      
        PORTD = 000000
        PAUSE   500  
        GOTO    START
