Hello, I need to interface my PIC with a dollar bill acceptor. The protocol is MDB. I have seen this project done with an AVR (I have purchased the product.. ) and the hardware looks pretty trivial.. But for the software, that is another story with the unstandard bit stream (start bit, 8bits, addressing bit, stop bit)

Has anyone worked on a project like this?

Any help would be great!!

thanks-Lee
