Hi Guys, There are two palm programs availible that will allow an ir equiped palm devices to function as a remote control for consumer ir (cir)devices. The OmniRemote http://www.pacificneotek.com/ The PalmRemote http://hp.vector.co.jp/authors/VA005810/remocon/premocce.htm NOTE:Neither OmniRemote nor PalmRemote work with Bang & Olufsen signals. http://www.bang-olufsen.com I would like to write a remote control program that will allow me to control B&O equipment with a palmOS based device ( Vx, VII or IIIc). B&O remotes use a carrier frequency of 455 kHz (yes 455 kHz) and a modulated pulse with a length of 200 ms. Originally, I though that the DragonBall processor could not reproduce that frequency. So, I did some research and discovered that the Philips Pronto (which CAN transmit at 455 kHz) remote uses the same processor (Motorola DragonBall MC68328 ) as the Palmpilot. http://www.pcseller.com/Philips_Magnavox_Pronto_TS1000.htm In fact the Palm Vx and Palm IIIc use the even faster Motorola DragonBall MC68EZ328. I realize the difficulty in learning B&O commands at the 455 kHz frequency. But the IR data transmissions of the B&O commands have already been captured with an oscilloscope, so no learning capability necessary. I also, have the timings and data format for the B&O protocol. The documentation is located in the following pdf file: http://members.aol.com/_ht_a/beodetroit/datalink.pdf IMHO, All I need now is to write a program that will take the stored information and format it and send it to the UART where the 455 kHz frequency would modulate the signal prior to transmission. Does this sound like it might work with the UART on the DragonBall processor or do I need an alternate UART/transceiver to accomplish what I want? Am I missing something that is obvious to you true palmpilot/Infrared programmers? Should I use the palmOS API or should I use assembler to write this program? I also need advice on which format to store the B&O commands (hex, binary or decimal). Additionally, I think that I will need to use a more powerful IrDA module to give the remote greater range. Do you know of a quality powerful transceiver (in a small package) that is IrDA compliant and can operate at the 455 khz frequency? Better, yet is there a more powerful (pin for pin) replacement for the current transceivers in the palm Vx, VII or IIIc? I have some programming experience in visual basic. Maybe one of you guys can help me or point me in the right direction? Thanks for taking the time to read this email. Any information or advise that you can give me would be greatly appreciated!
