Hi!
I found out the LCD_CON on OLinuxino-micro A20 could output LVDS instead of TTL which is default if I get it right.
Now I checked the FEX guide
http://linux-sunxi.org/Fex_Guide#lcd.5B0.2F1.5D_configuration
and this example
http://linux-sunxi.org/Cubieboard/LVDS
I dont see from here how to activate ports on A20 (for example PD00 - PD18) to represent the 19 pins required to drive the TFT-LCD.
My panel is QD15TL0206 and its pinout:
Interface Cable Pin Assignments
PIN NO . SYMBOL FUNCTION
1 VSS Ground
2 VDD Power Supply, 3.3 V (typical)
3 VDD Power Supply, 3.3 V (typical)
4 V EEDID DDC 3.3V power
5 NC Reserved for supplier test point
6 Clk EEDID DDC Clock
7 DATA EEDID DDC Data
8 Rin0- - LVDS differential data input (R0-R5, G0) (odd pixels)
9 Rin0+ + LVDS differential data input (R0-R5, G0) (odd pixels)
10 VSS Ground
11 Rin1- - LVDS differential data input (G1-G5, B0-B1) (odd pixels)
12 Rin1+ + LVDS differential data input (G1-G5, B0-B1) (odd pixels)
13 VSS Ground
14 Rin2- - LVDS differential data input (B2-B5, HS, VS, DE) (odd pixels)
15 Rin2+ + LVDS differential data input (B2-B5, HS, VS, DE) (odd pixels)
16 VSS Ground
17 ClkIN- - LVDS differential clock input (odd pixels)
18 ClkIN+ + LVDS differential clock input (odd pixels)
19 VSS Ground
Cheers,
