Post by thread:[PIC:] IRDA

I might have an IRDA application and have never done anything with IRDA before. I'm wondering if something like Windoze Hyperterminal can be pointed to an IRDA port and then the PIC driving IRDA would just (with appropriate encoding) consider this to be a terminal. This'd allow a full screen user interface with no custom code on the Windoze machine. Can it be done? Thanks!

> I might have an IRDA application and have never done anything with IRDA Most likely the mode you are looking for is IRCOMM, which is basically RS-232 emulation for legacy applications. Since there is only one "wire" for the IR stuff, some behind the scenes negotiations have to take place. (Which are transparent to the windows application program). BUT, the PIC program will have to implement the IRDA stuff. There are IRDA controller chips that may take care of all of the handshaking stuff for you, in which case your PIC app would be allowed to be just as stupid as the windows app (ie it thinks it is talking to a RS232 port) Check out http://www.irda.org for all of the protocol specifications. IRCOMM is most likely the one you want. -Steve -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

An easy option is to use the sx28 with the irda virtual peripheral. You can set up the code to allow transparent ir communications. I used a pic to talk rs232 to the sx28 and then to an IrDa computer port. This way the pic can do all the other stuff.
