Hii,
I'm building a simple rfid reader using U2270B ic from atmel. The output of the u2270b is manchester code. So i need to decode that manchester code (read by the u2270b from a transponder) using pic16f628a. Then i need to send the decoded machester code to my pc using the usart feature. I have done few simple project using pic but i haven't encounter this kind of difficulty. Hope you can help me!!
I have never done something like that, but judging by the above link, it shouldn't be too hard.
You know how to program a PIC in either C or Assembly, right?
By the looks of it, you simply have to synchronize to the data stream once, and then read away.
You'll probably want to buffer small portions to send in parallel using the USART. If you need help with the USART part, Microchip has some application notes that will detail this on their website.
