Populated IrDA?
I see in the tech specs of the FreeRunner that the CPU has IrDA built in, but I cant find anything listed in the specs that shows it as being used. However I saw a youtube interview the other day that I believe had a passing mention about it being available for use. Could someone please let me know if it is or is not populated / usable?? I really want to be able to use my FreeRunner as my universal remote using LIRC. Thank you.

Maybe related(also GTA01, no schematics;-( for 02): what's the use of TX-IRDA, RX-IRDA on 1. & 2. ring of headset connector(3,4), ending on GSM-module pins of same name, enabled by pulling 3. ring to GND (4.ring, base)? How is this supposed to be used? In case of an external IR-adapter: where to take TX-LED power from? I suppose mic bias (2k2) won't suffice. Near OT: what's "Hold" on 3. ring of same connector supposed to signal to CPU? RC (A/D - R-cascade. in case: supposed R-values?)? An application sample for full featured external (RC-)headset / other (IR-)device(s) might help! completely OT: ambient light sensor? (PCU is supposed to support...) jOERG ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Sorry: "Hold" on 1.ring aka tip / MIC. 3. ring = "jack insert sense" / LOut (/ IR_enable). j ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Thank you. IrDA and CIR (consumer IR) are usually not the same thing. If you start looking for the actual components you'll see there are several wavelengths of light in use. OTOH the phototransistors used in the IR receivers are sensitive to a range of wavelengths (sensitivity vs. wavelength is a bell curve), so they don't always have to match exactly. The Agenda (an early Linux PDA back in 1999 or 2000) had a CIR emitter for just that purpose. It was also possible to use the Palm's IrDA port for remote-controlling your TV etc. but the range was very short, like 3 feet or less. Another company was selling a CIR emitter you could plug into the HotSync port to get longer range. Of course if you install an IrDA transceiver in your PC, you could use an IrDA handheld as a remote for it. But then why not use Bluetooth or WiFi? IR is too directional. ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
