New to PIC

Here is my code, it flashes leds on PORTA.0 and PORTB.0

ADCON0 = 0
ADCON1= 127
define OSC 4
led var PORTA.0
sink var PORTB.0

loop:
toggle PORTA.6
pause 5
high led
pause 5
low led
pause 5
high sink
pause 5
low sink
goto loop
end


PORTA.6 is just low, it does not toggle or go High if I change the code.

The schematic is simple, I connected VPP, +5, Gnd, PGD and PGC.
I have 470 ohm resistors from the PIC to leds connected to GND.

Could it be the clock output function? How do I set INTRC_OSC_NOCLKOUT?

The above talks about how to set the configs.
You can do it in your code or just modify the PICs *.inc file.

Well, nothing I have tried with this has worked, I can get it to work in Swordfish Basic but Microcode studio is not what I expected for the Price they charge.

Has anyone else gotten a 18F1320 to work correctly with PICBasic Pro?

I am beginning to regret shelling out good money for a product that does not work as well as a free compiler.

Did you get the OSC set correctly ?

Post you config settings.

Hi Mike,

Welcome to the forum.

I was reading through this thread and it looked like something Savnik pointed out might not be too clear. (But very correct.)

Porta.6 and a.7 are reserved for an external oscillator, so they can't be used as regular pins unless you put a config line in PicBasic Pro to explicitly enable them as pins. That's probably why the other LEDs work, but those don't.

Since I don't know anything about Swordfish, I can't compare how it does this. For me, once I started understanding the setting of fuses, things started getting smoother.

Hang in there. I find PicBasic Pro to be very powerful. So far, whenever something doesn't go as planned, it is just a little thing I haven't learned yet.

OK, I got the OSC set with OSCCON =$60 so its not running at 37khz anymore, which makes sense that the pause statements were way too fast for the result I was getting; pause 5 is way too small for what I was used to in basic, now pause 500 is more like it.

As for setting the fuses, I think I will need help figuring out how to do that.

First off read the thread I linked to above. Then let's just change the configs in the Inc file. If you were going to change things often then doing it in code is handy.

Go to the PBP directory and find the Inc file with your chips name. There you will see the config settings. You may want to male a backup of the file.

Then go to the MPASM directory in program files and find the coorosponding Inc there. The microchip Inc near the end has all of the possible settings.

Change the PBP Inc to the way you want it.

I am on my phone at the moment so I can not show the exact change.
