... the irda specification is horrible the protocol stack is huge and highly complex . "IRDA" covers a whole multitude of protocols for various different applications. There is a simple protocol (SIR?) for low-speed, UART-like comms that is perfectly appropriate to 8051s: basically a pulse of IR indicates a '0'; no pulse indicates '1' There are some chips that do a direct conversion from UART output to this kind of IRDA - maybe the tfds4500 is one such? (if the OP posts a datasheet link, we could check it and see). Maxim has some application notes about it. It's been discussed before - which is why the original thread scored a massive -4 for "Didn't search first"!! Must be some kind of a record... |
