Project: FM Tuner.

[iwantanimac]

Okay guys. I need everyone here who's got any knowledge of C programming to help me out.

As stupid as it sounds, my first try at programming is going to be to try and get our much missed FM tuner working.

All the code is available, and there, however, it doesn't actually work.

I talked to Barry Wardell (And anyone else willing to help out) on the IRC last night, and copied the relevant parts of it [Here]

It seems Barry, try as he might, couldn't get the tuner to turn on. The main issue here seems to be getting power to the tuner. According to Barry, everything he's tried thus far has given no response through those inputs we know of (And how to use) so we need to do something.

I plan to set up as many links as possible for people to help out here. Basically, we need to try and figure out how to give power to the FM tuner (And/Or get a response of some kind that's not apparently random).

So i'm going to be collecting all the links and posting them to the Rockbox Wiki. Anyone who wants to help out, make sure you're signed up for the Wiki and add any notes you think are useful there.

Here is the Wiki URL:

Thanks, guys.

I dont know C, or any programming language. I completely support the idea. Suggestion of a possible way to figure it out: When you dual boot, are you essentially running the original firmware over rockbox? If so, would it be possible to write a code that logged what and when the original firmware did (ie gave power to the radio in this case)?

I could be totally wrong, just a thought.

I don't think that's exactly how it works, but i'm sure some disassembly could be done.

I'm very bad programmer on C, i tried many hours to have a better scrollpad but i didn't managed to make it work. If we test on H10 some thgins, could we brick our H10 ??

[iwantanimac]

I very much doubt we could brick the H10 (As in non-bootable) however, i guess the potential might be there for something to go wrong with something.

At worst it may kill the tuner. I very much doubt it would, but i guess it's possible. Ill ask later on IRC if I have the chance.

In summary, I doubt any harm can come from this project, however the potential may be there.

Bold because I'm that confident at this point that it won't brick anything.

This is out of my skills... ;-(

[iwantanimac]

I'm sure you could help somehow... You seem to know your way around the code alright.

If someone tells me exactly what i have to test, just do it ^^.

i had bought H10 20gb 7days ago and i installed dual-bootlable rockbox....when i want to listen radio i boot it orginal OS....

i know little C/C++.... i looked rockbox open source codes but i haven't understood anything yet.....

[iwantanimac]

Well as i think i said, my past programming experience has been in Windows, and using Visual Basic .NET, so it's pretty alien territory here, however there are some paralells between the two languages which i've picked up pretty quickly, however, i'm sure C isn't object-oriented, so it'd be a steep learning curve anyway, especially seeing how nearly everything done is manual - you have to code it yourself.

Up on this ?

Unfortunately this is a rather difficult project. I need some people with real world knowledge to help. I'm messing with the source code now, but i haven't touched the tuner side of things (I don't know what i might stuff up there) and doing more practical (Programmatically) and easy stuff right now. Once i feel comfortable enough with the source i might give it a real crack.
