Hi,
I have LCD - UC242908 (SamSung) and I've found this infos.
On the back there is M38067 mcu and the 16 pins connector of the board is wired like this :
16 - pin 74 mcu (P67/AN7)
15 - pin 30 mcu (Vss)
14 - pin 75 mcu (P66/AN6)
13 - connected to R7 on the board
12 - pin 76 mcu (P65/AN5)
11 - pin 71 mcu (Vcc)
10 - pin 77 mcu (P64/AN4)
9 - connected to R3 on the board
8 - pin 78 mcu (P63/AN3)
7 - pin 26 mcu (P41)
6 - pin 79 mcu (P62/AN2)
5 - pin 27 mcu (P40)
4 - pin 80 mcu (P61/AN1)
3 - pin 23 mcu (P42/INT0)
2 - pin 1 mcu (P60/AN0)
1 - pin 22 mcu (P43/INT1)
I think that data bus is :
2 - 4 - 6 - 8 - 10 - 12 - 14 - 16
D0 D1 D2 D3 D4 D5 D6 D7
MCU power :
11 = +5v
15 = gnd
But for 7, 5, 3, 1 I don't understand fonctionnality and
pins 13 and 9 are connected like this (I think that is LCD power but I dont know how to connect) :
Code:
____R________________________________________

13 -------R--------------------------T R
| |
| |
--------T |
| |___ pin 10 mcu(P57/DA2) |
| |
+---------------------------------------|
|
9 --------R----------------- T
|
GND
Where R = resistor and T = transistor (npn, pnp ???)
how to conect this pin ???
Thanks in advance
