Now to something completely different

[Ted's]

Now I am approaching a different task.

I connected a TSOP-IR-Receiver to my device being run by a 16f628a. I want to control it via palmos 3.5 irda or own codes.

Question: Who has already accomplished that task and can give me reliable sources?

I remember seeing an APP note on the microchip site a couple of years ago that talk about a project like yours. Do a search there.

Have you done any programming for the palm? If so, (just curious) what developer are you using?

Hi, the irda signal is not modulated; so, you first need to get rid of the TSOP-IR-Receiver.

Adding irda capability to a PIC could be achieved a number of ways. Microchip themselves have irda codec solutions. Or, look up www.sirpic.com. The guy there, Ravi, specializes in Micro-to-irda solutions in varying degrees of customization. At this site, you'll also find a software-only irda implementation for PICs contributed by another person.

Or modulate the signal. This is what I want to do. Being dependend on light situations has always been the greatest drawback of irda.

Is there a sorce code on his site? I couldn't find any...

I am using a vb-clone for palm programming.

The only option is to use IrDA.

If I use IrDA,open the connection and send the value 3211 using a baudrate of 38400 and having the TSOP attached to the pic, what should I receive and how do I convert it back to the value via pbp?

Please no links this time. I want to see this problem solved step by step so I can create a code suitable according to this example.

I found it. Nice. One drawback is that the tsop is limited to - I guess - 1k bps meaning that the irda requiring 9600bps won't work so I'll have to work with my own codes and low-level. I hope that low - level does not mean assembler though.
