H120 remote control
Chronon:
Rockbox shouldn't crash in this case. It would be worthwhile to post a bug report.

But would LOVE an IR remote - the H120 is a permanant fixture in the living room, being connected to a 3.5" drive. Is one vote enough for you to ressurect the project?!

I've looked after the hardware yesterday evening and still found it lying around. Haven't figured if it's still working to any degree, and haven't searched for the firmware. It will definitely include an Atmel controller so for building it you'd need to flash it. If I finish it, no promises (yet :) ).

ok, after some hours of work I have a working prototype. It tries to fake a h300 non-lcd remote. As a result, it can use the buttons Play/Pause, Forward, Rewind, Volume Up and Volume Down (i.e. the buttons that remote has). I'm using an old Hauppauge remote for that which sends RC5 codes. There's also a strange problem: when the receiver is connected the device won't power up. I haven't figured what's going on there.
Anyway, the current schematic is here: http://www.alice-dsl.net/dominik.riebeling/rockbox/h100remote.png

Wow, I didn't even get a chance to respond to your last post!
Thanks for the schematic. I have an old Hauppauge remote myself somewhere so seems like a great starting point.
When you mention the device won't power up are you referring to the player itself? If so, do you mean it won't power up from just the remote or from any of the buttons on the player too?
You're a star, I'll let you know how I get on. With my limited electronics knowledge, I may be some time...
I love the internet!

Yes, the player itself. No idea why this happens, but it seems to be related to the circuit -- if I erase the memory of the controller the same thing happens, so I think it's safe to say it's not caused by some wrong initialization in the controller doing weird things. Let's see if I find some time to look into that the next weekend.
You can't power up the player using the remote in any case: first I thought the remote isn't powered when the player is off. Later I found that there is some power supply, but it's not the normal 3.3V and therefore won't be sufficient to make sure the receiver is in a usable state.
If there is enough interest I might consider doing a PCB. So ... are there others around that are interested?
Edit:
I've pushed the current state (code for the controller will follow later, most likely this weekend) to https://github.com/bluebrother/ir-remote
Edit2:
Found the problem that prevented the player from powering on, it's working fine for me now. An updated schematic will follow in the github repository later.
bonapardo:
Keep up the good work!
btw, I'm having problems viewing the updated schematic - do I need a special viewer?
Once I've cobbled everything together, I'm hoping to attempt navigation control (as I can view my large text on the iRiver from the sofa). What was your approach to working out what the controller needed to output (i.e. what the iRiver was expecting to be sent to it)? What/how did you measure? Do you think, with a spare LCD remote, that it should be pretty simple for me to program the extra commands into the controller - or would I need to redesign the circuit? The latter is pretty much out of the question for me!
Thanks again...
