Wiegand data and com port

[hkwkok]

Dear Felch,
Sorry, i need the one is PROXIMITY.asm, which is you posted on 4th march 2005, and the link is http://parsek.yf.ttu.ee/~felc/proximity.asm still not working, is it complete project? if yes, can i have the hex file?
By the way, how is James(jmaloway) done this project? I live in Canada too, can we share the experience?

Hi!
Understood you wrong.
Yes, proximity reader is a stand-alone device. Here's the complete project (MPLAB).

Fekch,
Thanks for your files, actually i using the HID ProxPoint Plus reader(wiegand format), i want to convert it to rs232 format, because i have a lot of used proxkey on hand, but can't see the card number, can i use the Windows' HyperTerminal to retrieve the number?

And my last question is the pin connection of PIC12F629 as below?
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.


Thanks Again! i hope the project above can be done my work.

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 am aware, HID readers output 36 bits. In this case data will be rejected
I do have a combo lock project for 36-bit HID readers but try first this code. If it does not work, I'll publish the other one. Or- you have the source, you could modify it by yourself also. And estonian learn estonian via my comments Actually, it's good you probably do not understand it...bad style...

Felch,
I tested the code this afternoon, looks like that's not working, i use JDM PIC programmer with icpro105D to program the chip (PIC12f629). i put 1K resistor between pin 6 and +5V, also, measured the both input (data0, 1) and output (pin7) with oscilloscope, there are no signal from pin7 when i put the proxkey on HID reader (having beep sound from reader), i don't know is it the wiegand format problem?
I have experience on writing code for ATC89c51 and some AVR, but not PIC, can you post your combo lock project or do the code modification for me?
Thanx in advance.

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 reader and count pulses form both channels. If count>26, code will not work definitely.
Lock code is attached. Reads 36-bit wiegand and saves card numbers into PIC's EEPROM. Key "Tühista kaart" means "delete card", other key is for registering card.
To register new card press and hold the "registreeri kaart" key and show card to reader. After beep data is saved.
To delete a card, procedure is the same except that you should use "Tühista kaart" key.
Pressing both keys simultaneously opens door lock (could be used for opening the door from inside).
Have fun!

Felch,
Thanks for reply, i don't have digital storage scope, anyway i found the HID ProxPoint Plus reader is 36-bit wiegand format.
On your RFIDlock project, is it using the Clock-and-Data format reader?

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...

Yes, i found the asm file which indicated the GPIO5 connected to D0 and GPIO4 connected to D1, unfortunately, this project doesn't have the rs232 output to computer for card # display.

Anyway, i will try to modify the proximity.asm for 36bit wiegand, hopefully, i can make it work, but i need a lot of study.

Thanks,

William
