This is as far as i got, can somebody please help me with the errors mentioned below?

DEFINE OSC 20 ' Define crystal as 20Mhz

ADCON1 = %111 'FRC (clock derived from a dedicated internal oscillator = 500 kHz max)
ANSEL = 0 'The ANSEL (91h) and CMCON0 (9Ch)registers must be initialized to configure an

TRISC = %10001111 'Set PORTC for serial coms and pins 0 - 3 as inputs
TRISB = %00000000 'Sert PORTb as outputs and for use with the ICD2

no such error here. Which version of PBP are you using?

[Andre_Pretorius]

MPLAB 8 and PBP 2.46, i also do not get the error with microstudio

[mister_e]

mmm, sounds like a corrupted file, did you tried to re-install PBP and it's patch for 2.46?

thanks, i created a totaly new project and copied my code into it, it seems to have fixed the problem it compiles now without problems.
is there any thing you think i left out to have the pic do what i setted out to do in my first post?

Nope, it disable all ADC channel <7:0>.
http://ww1.microchip.com/downloads/e...Doc/41250F.pdf
PDF page 45, Ansel Register.
should be
ANSEL = %00011111

PDF page 183, ADCON1
ADCON1 should be
ADCON1=%01110000

To disable comparators, cm<2:0> bits have to be = to 111

so PDF page 118, CMCON0
CMCON0=%00000111

Acording to me this chould read the 0 - 5v signal on PORTA.0 and sends the digital value to hiperterminal, nothing seems to happen ,any help please
Also i have just bought myself a ICD2 is there any special code i need to add to use the debug functions?

Hi Mr. E and all others!

I am new to the LCD "modules" in the 16F913 chip. I'm trying to get a basic breadboard going here using the minimum setup required to just send 2 digits to 2 displays. From there I can figure out everything else the chip needs to do. It's these damn module parameters that is screwing with my head. Specific pins to displays can be any arrangement for now.

The App Note AN1070 and chip data leaves me confused when it comes to using PBP (v2.60) since data references are all in Assembler. Has anyone worked with this chip to arrive at a simple setup to map the pins, and how to setup the "mapping"? Do you need to create a lookup table to output the digits you want. The more I read the more I'm either missing the boat or reading too much into the minimums required to talk to the displays.

Mega thanks, Frank
