Moved:How do I connect a dollar bill validator (MDB) 2 a PIC

[trend]

mdb/icp

Hello, I need to interface a dollar bill validator to either a PIC or AVR. I have a schematic on how to do this... But lack software.. And am a little confused.

I know it is 9600baud, 1start, 8data, 1special data packet, 1stop.

But I am not sure how to use the 1special data bit.

Does anyone have any suggestions or code?

thanks! Lee

If you use a PIC with a USART it is much easier (PIC16F87x for instance). The 9-th bit is generally used for parity. The USART will receive it if you enable it in the RCSTA register. You can then retrieve it and use it for whatever purpose.

If you want to do it all in software it will be harder but you will learn more.

interesting.. How do you reconfig the uarts into letting the 9bit do whatever I want?

thanks guys!
