Each pin is a byte. But only 1 bit of those bytes is significant, the other 7 are not. But yea, you always read/write 1 byte for each pin.

I really recomment reading the data sheet, it helps.

RockRabbit:
I can confirm that GPIOD pin 7 is the button light for the Sansa c250.

Thanks Kugel. The code worked fine.

Could you add it to the hardware mappings page for me please.

Hmmmm...Whenever I try to run Rockbox, the bootloader starts and I see the Rockbox logo, but then, it says

I'm using the latest in SVN, and I'm not sure why this is happening! I'm trying to figure out what the problem is, does it mean internal SD? Even if I take out my SD card, I still get the same error. I just don't get it.

I'll add it to the hardware mappings page for you, RockRabbit.

FlynDice:
I was getting the SD : DATA TIMEOUT until I took all the music off my e280, then It booted all the way into the menu just fine.  Buttons didn't work though so I tried Domonoky's button patch and buttons sort of work.  The down button won't move to a lower menu.

I did get an ogg file to play quite  nicely though by using a fixed.cfg file.  I had rockbox start in the db menu and right arrowed my way to a music file.  After the one file played though the screen goes dark and I need to reboot.  Any other patches to get the down arrow working?

Great! I'll add it.  I'll maybe have a look at the c200v2 OF for the LCD if I have time.

Another thing: I think it's essential for safety that you find your USB "button". Turn the player on with USB and see if a delay happens or not compared to starting with the power button.

It would be very helpful if start creating a c200v2 target in the Rockbox tree then. So we can  build a basic bootloader using dual boot and test code *easier and safer*.

Edit: Uhm, now that I think about it. Finding USB  (and maybe some other buttons) should be essential for dual booting anyway, since I can imagine that dual boot with the power button will be somewhat difficult.
