Wiegand data and com port

[pmatyas]

I'm interested your converter, can you send mee an schematic and program source in PIC 16f628?

regards,
Mathias

It's quite simple. Device sends pulse on Data0 if it wants to signal that bit =0 and vide versa. There are 26 or sometimes 40 bits including parity in beginning and end.
Have wrote decoder with rs232 output for 12F629 and 16F628. I will post code, if interested.

Hi Felch,

I think you have done a fantastic job and thanks for sharing. I am also new to this but it all makes sense and can't wait to get my hands on the microchip and start experimenting. While I'm still finding my feet please can I ask your help (which I am sure won't be too difficult)? I need to convert the 26bit Wiegand to RS485 for the sake of reading up to 1.2 Kms away. If its not to difficult do you think you could post modified code for me?

Many many thanks!

Richard.
