Wiegand data and com port

[jmaloway]

Ok, I think I get it now.

I am going to head over to my parts supplier tommorow and pick up a PIC12F629.

When I get the chip, I'm supposed to get the OSCAL value by doing an upload from the chip and then choosing to use the value from the chip, right?

Then, once I get "proximity.asm" loaded onto the chip, the pin connections should go as follows:

Pin 1: +5V DC
Pin 2: Prox reader "Data 0"
Pin 3: Prox reader "Data 1"
Pin 4: No Connection
Pin 5: No Connection
Pin 6: No Connection / +5V
Pin 7: RS-232 Data out
Pin 8: Ground

No crystal is needed as the oscillation is taken care of by the internal oscillator.

Is this correct? :-)

Thanks again,

James.

Yep. That's correct.

Felch,

I went out today and got the PIC12F629 - but I have one question before I do anything... what programmer and software do you use to burn PICs? I was using Ponyprog 2000, but I have also tried IC-Prog which seems to have a much wider range of devices which it can program. Whenever you go to program a device, there are a multitude of options that you can choose, I beleive they are all for the oscillator. Which one should I use?

Thanks again,

James.

What do you mean with options? WDT, OSC? If so, they are processors config options, correct values should be read from the .HEX file. Anyway, switch WDT off, OSC to INTRCIO and MCLR off.
I use a programmer from www.kitsrus.com -> KIT128. Extremely reliable device!!!
I made it myself, pcb drawings and PIC code files are given. IC-prog is also goodbut serial port programmers usually do not work. Not enough power from modern ports. Use PPwin if you have to.
