Rockbox Development > New Ports
Cowon D2
andiator:
It seems like D2's touchpanel and PCF50606 are not multitouch able. That's a hardware issue and there is no workaround. The only thing working are the gestures.
Yeeze:
Would have been nice, but I can live without multi touch...
shotofadds:
It's only possible to receive the X/Y coordinates and an indication of the size of the area touched (this can be calculated from the P1 and P2 values, somehow). With this information, could "multi touch" be simulated by testing whether the area touched grows or shrinks?
It's a thought for the future, anyway. I personally don't intend to do much with the touchscreen for the moment (priorities are getting the filesystem working, booting the Rockbox menu, and then sound).

Thanks for that - I've updated the code in SVN now to detect the various combinations. Could you check it displays "2 banks * 1048576 pages * 4096 bytes" for the 8Gb player and "1 banks * 1048576 pages * 2048 bytes" for the 2Gb?

I avoided the issue completely by building tcctool on Windows XP - I realise that doesn't help you...

Confirmation from me on the 8Gb player that it's detected correctly as stated by the above figures (this time I used the rockbox.iaudio file). And I still have time to brew some coffee while it counts memory. After 10 minutes it's at 2.4Gb... Should I walk the dog while it goes to 8 .-) No way to cancel the count, it seems.

Multitouch... yes, I didn't see the plate resistance stuff, so it may be possible to have two finger gestures. But it's a long way to get a good and native support for touchscreens in rockbox. At first let's simulate some buttons. I've found a good description for touchscreen interface under http://www.atmel.com/dyn/resources/prod_documents/doc8091.pdf.
@shotofadds
In open moko project I've found some source code for PCF50606 except touchscreen handling. The first one is a patch file with battery/rtc stuff in it. The second one simulates PCF50606 for qemu. I can pm them if you want.
And besides, can we (the others) somehow help? I'm a software developer so I can code. Is there anything that can be done without deep D2-hardware knowledge?
