Thank you. We have now determined that your player has the backlight on GPO A2.
Code:
0000 = 0
0001 = 1
0010 = 2
0011 = 3
0100 = 4
0101 = 5
0110 = 6
0111 = 7
See?
Now we have to figure out LCM's reset and command/data pins.
Try the following commands in s1giveio (excluding the comments):
Code:
o 2 18 ; select CE3
o ee 7 ; turn on all GPO A (backlight should be on now)
o ef 0 ; set GPIO B in GPIO mode
o f1 0 ; disable all input on GPIO B
o f2 35 ; turn on all the GPIO B
o f0 35 ; enable output of GPIO B
o f3 f ; set all GPIO C to output
o f4 f ; turn on all the GPIO C
o f6 0 ; turn off input on GPIO D
o f7 3f ; turn on all GPIO D
o f5 3f ; enable output on GPIO D
o f9 0 ; disable input on GPIO E
o fa ff ; turn on all GPIO E
o f8 ff ; enable output on GPIO E
o fc 0
o fd ff
o fb ff ; do the same for GPIO F...
o fe 7
o ff 7 ; ... and GPIO G.
o ee 4 ; turn off all GPO A except backlight
o f2 0 ; ...the same for B...
o f4 0 ; ...C...
o f7 0 ; ...D...
o fa 0 ; ...E...
o fd 0 ; ...F...
o ff 0 ; ...and G
; ... then turn them back on again...
o ee 7
o f2 35
o f4 f
o f7 3f
o fa ff
o fd ff
o ff 7
w 8000 1 1 ; start oscillation
r 8000 2 ; read register 0
