Hi!
No, this project uses wiegand but circuit was from another code, that read magnetic stripe format. Actually i think it is possible to make the code autodetecting but...never tried it. Yet...

What does your scope show on inputs? When using a digital storage scope, connect on channel to dat0 and another to dat1. Use single cycle (freezing picture after signal ends) mode. Show card to...
Yes, this is correct pin-out. Pin 6 should be connected to +5 via some resistor (say, 1k). If grounded, output will be disabled.
Note that this code only handles 26-bit wiegand format. As much as i...
Hi!
Understood you wrong.
Yes, proximity reader is a stand-alone device. Here's the complete project (MPLAB).
Linkworks but may-be there are problems in some servers. Anyway here it is attached.
I can't give hex file, this is not a complete project but only fragment of a larger one.
About reading...
Hi!
Checked, link works OK. could be some server problem,so i uploaded the code to forum directly. Have fun!

Thanks!
Actually it was a fun-project for the annual electronics-hobbyists and -engineers meeting (hold in Tallinn, Estonia every august), nothing more.
You could imagine the roar of laugh when,...
I see biggest problem in...the LCD screen itself. In car it must have enough contrast at daylight and it must be easily readable (but not disturbing!) at night.
Everything else is a question of...
Hi!
I needed such code for one project but..net was full of "usual" serial bootloaders. So i was forced to write it. Hope, this example will help somebody!
Code (source in assembly and .hex file)...
Hi!
I do not know, if it helps you but just in case..
I developed a PIC-"filter" of NMEA-messages. Pic12f629 (INTRCIO mode) monitors GPS (Falcom JP7 but this should not be important) output stream...
Yes, i guess that the code could be adapted. You only have to write a routine for storing numbers in EEPROM. Only thing that might get disturbing is PIC's oscillator frequency deviation due to...
I do not know exact PICBasic syntax but i guess that it is PulseOut. Anyway, you have to set D0 low for some time to send a zero nd D1 low for the same time to send one.
Both data lines must not be...
PS/2. Forgot circuit...
Actually...what is wiegand after all? I have seen RFID-card readers with very different timings but they all claim to output wiegand...
Anyway, may-be this helps (look at page 2).

Hi!
After noticing a similar project at sparkfun page i decided to write my own code. It emulates old phone with rotary dial and it also makes an attempt to ring a little bit. Works with Ericsson...
Hi!
This piece of code sends contence of databuf to PIC's pins in pseudowiegand format. Hope it helps. (Comments translated to english, i do not expect you to understand estonian....)...
A copy of my reply to somebody who asked questions like yours. Hope it helps you .

Hi!
Wiegand timing is a difficult question. I found one doc (...
Can't read it directly because ia wanted to have an industrial reader (nice look etc, you know). One option is of course replacing industrial readers electronics with mine (i developed code that...
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...
Yep. That's correct.
PIC16F628 has 16 i/o pins which are divided into 2 groups - ports. They are PORTA and PORTB. naturally they have different pin numbers! Powerful PICs have more ports (18f452 up to PORTE). PIC12F629...
GPIO1 must be connected to +5V, preferably via 1k resistor. Since there is an internal pull-up resistor in PIC, you may also leave this pin floating. You can comment checking this pin out from code...
Hi!
Serial string "ID xxxxxx" is output on GPIO0 if GPIO1 is at high level (enable pin). Taking GPIO1 low will disable output. Output speed is 4800 bd.
If you mix up D0 and D1, data will still...
Hi!
It must be a PIC12F629, not 16f628! That's first. Then, After powering up the chip has no tasks, nor does it output anything. Only after you have presented a card (wiegand data arrives from...
Hi!
Sure i could send you preprogrammed chip but is this really what you want? It could cost a lot...
Wouldn't it be easier to fix your programmer? What device are you using and what errors does it...
