Pic Start Plus Help

[shawn]

Hello
Im having problems programing a Pic 18F458 chip using Pic Start Plus. I just bought the Pic Start Plus to use and I cant seem to get it running. I have been using a picQuik programmer for the last couple of years and have had no problems with it.

here is the complete example code I tried to use just to make sure the picstart was working

pause 1000
trisb = 0
portb = 1

I use microcode studios and PBP 2.46
When I open the Hex file in MPLAb 7.41 and program it says that it worked and verified. But chip does nothing.

When I program the hex code into the chip with my Picquick it works.

I thought maybe in MPLAB I was not getting the config bits to program but it appears when you hit program it programs everything to the pic.

If I put this Code in Microcode compile and then load hex file with MPlab it works.

Pause 1000
TrisB.1 = 0
PortB.1 = 1

Please Help
Is there an include file that I am suppose to be using in my microcode program.

Hi,
So, is the problem with PICStart/MPLAB or with one of your posted code snippets?

Microcode studio will automaticly include the device specific file(s) based on which device you select in the drop-down list in MCS. You can then either set the config fuses in your program (search the forum for info) or set them manually in MPLAB.

In MPLAB: Enable the PIC-start, select the desired device and import the .hex file. Now goto Configure/Configuration bits and check that everything is as it's supposed to be, then program the chip.

try this

pause 1000
trisb = 0
portb = 1
here:goto here

so your code does not go off into no-where (I am not sure what your other programmer does with the unused space but, depending on your MPLAB settings, you may have stuff there)

Thanks you guys.
It was late last night while I was working on it and my code was supposed to be simple to make sure it was working. Problem is Portb = 1 would make portb.0 = 1 and the rest of portb 0's. Im not using portb.0. Thanks for you help though. I'll try to get more sleep before I ask another stupid question.
