I played around with the cabbiev2 theme settings on my e280v2 and found I could make the scrollwheel work if I change the background color to white and don't use the backdrop. It worked one bit off of white(EFFFF...) but I haven't been able to test to failure so far. I did set the top adjustment to the middle of the settings limits and scrolling failed though. Would this point to an lcd driver issue?
EDIT: For background colors scrolling only works for RGB: values FFXXXX F7XXXX EFXXXX and E7XXXX. The green and blue values all work fine it's the red values that seem to be a problem.

I would think so yes.

Back on the e200v2 REC button, I'm trying to figure out if I'm chasing my tail here a bit. I've got it seemingly working in the main rockbox app. I say that because the backlight and buttonlight both come back on when I push the rec button just like any other button. I also enabled recording in the config file and a long rec press takes me into the recording menu. There do not seem to be any "phantom" rec presses in the main rockbox area aside from on bootup. On bootup rockbox behaves as if the rec button is pushed, ie it clears all settings and a grey box appears saying settings cleared. I have managed to bypass the rec button on startup to get into rockbox with a working rec button however. Playing around with the plugins though has made me wonder what else may be going on. BlackJack gets stuck in a button switch because it continuously pulls the BUTTON_REC code off the button queue even though the rec button isn't being pressed. There's also one of the higher bits set so it gets stuck. Sudoku behaves properly when I press the rec button but there are phantom rec presses when I turn the scrollwheel. Because of the startup issue I'm not sure if this is a rec button issue or a plugin issue. Any thoughts?

Just letting you know, the ams sansas should now have working radio, except for the c200v2.
Most of them seem to use an si4702 FM chip which is supported by the si4700.c driver, the m200v4 uses a tea5767 FM chip supported by the tea5767.c driver. There is no radio yet for the c200v2 because we don't know yet how to talk to the FM chip.

I believe the rec button and scrollwheel issues on the e200v2's are basically the same problem. I changed the background color in blackjack to LCD_WHITE and the rec button gets read just fine. This actually makes the bootup issue with the rec button also make sense. The background color when rockbox boots up is black. This is the timeframe I have been bypassing. Once I make it into the menu's, I've set the background color to white and rec and scrollwheel work fine. I'm thinking that for some reason any background color that doesn't have it's red component maxed out is altering DBOP 15 and 14, and maybe also 13 but I can't tell yet. Does this bolster the LCD driver as the culprit?
