I am sorry that I am completely new in this field and have no idea on
any of those FIR, SIR, CIR, IrDa terminology. To quote from our spec:
10.9 Consumer Remote Control (TV Remote) IR (CIR)
10.9.1 Overview
The CIR is used in Consumer Remote Control equipment, and is a
programmable amplitude shift key (ASK) serial communication
protocal. By adjusting frequencies, baud rate divisor values and
sensitivity ranges, the CIR registers are able to support the
popular protocols such as RC-5, NEC, and RECS-80. Software driver
prgraomming can support new protocol.
10.9.2 Features
1. Support 30kHz - 57kHz (low frequency) or 400kHz - 500kHz
(high frequency) craarir transmission.
2. Baud rates up to 115200 BPS (high frequency)
3. Demodulation optional
4. Supports transmission run-length encoding and deferal functions
5. 32-bytes FIFO for data transmission or data reception
Dose this means that the hardware transcriver can do all of the FIR, SIR,
CIR and IrDA thing as long as there are software protocol stacks ??
Dan, could you please tell me the difference among all this *IR stuff ??
BTW, the IR module (SiS950 Low Pin Count) was brought from an company
called ITE.
