i am trying to work ir control for the boe-bot. i can send and receve betuen too bs2 chips ,but what i need is a program to work with a universal remote or other IR signals other than a sony ir remote!!!

what i need is a program that can detect an IR signal and give it a value or number so i can get a signal from an unnoun IR sorce and translate into something i can use??? mad.gif

    Not going to happen without some external intervention. The SIRCS is a fairly slow protocol which allows it to be decoded by the BASIC Stamp and similar processors. If you're looking for something more universal, you might consider using SX/B and an SX at full-speed.

    BTW, if you're going to get fancy and create a vote, you should probably add an apporiate title to your thread....

    Well, then, you're probably out of luck unless you want to use the Sony IR protocol. As I indicated, its design allows the BASIC Stamp to receive and decode SIRCS signals without trouble -- other protocols aren't so easy. You might try a web search for a device (coprocessor) that allows you to read any IR codes. Or you could connect a 'scope to an IR receiver and sus it out by hand....

    The January 2005 issue of Servo Magazine (I just opened it) shows how to decode unknown IR remote signals -- but it uses a PIC coprocessor to measure the pulses before sending data to a PC through a serial link. A Basic compiler for the PIC is used, so I imagine one could port the program to SX/B.
