Im having headache of wiring display (SN)ERM24064
I'm using constructor (paralel)
U8G2_T6963_240X64_1_8080 u8g2(U8G2_R0, 8, 9, 10, 11, 4, 5, 6, 7, A0, A1, A4 ,A2);
from Arduino's U8g2 library (GraphicsTest)
where pins wirnig is (3 times checked wiring ):
A0 -> WR -> Dsp 5
A1 -> CE -> Dsp 7
A4 -> CD -> Dsp 8
?? (missing Read Signal)
A2 -> Dsp 10
8, 9, 10, 11, 4, 5, 6, 7 -> Dsp 0/7
VSS (+5V) -> Dsp 3
GND -> Dsp 1,2,4,20,22
Pin Names
U8g2 instruction:
cs, cs1, cs2: Chip select, datasheet names: CS, CS1, CS2 or CE
a0, di: Data/instruction register select, datasheet names: A0, DI, CD or RS
rw: Read/write line
en: Read/write enable
d0 - d7: Parallel data
reset: Display reset
display's datasheet:
1 | GND | power GND
2 | GND | Power GND
3 | VCC | Power positive
4 | V0 | Negative Voltage (LCD contrast)
5 | WR | Write Signal
6 | RD | Read Signal
7 | CE | Chip Enable Signal
8 | CD | H: Data L: Instruction Code
9 | NC | No connection
10 | RST | Reset Signal Input
11 / 18 | DB0..DB7 Data Bus Line
19 | FS | Font selection
20 | VEE | Negative Voltage Supply
21 | LED_A | Blacklight Anode (+5V)
22 | LED_K | Blacklight cathode (0v)
Datasheet:
Only thing I'm displaying is randomly horizontally lines when is presed reset button....
What im missing ?!?
I do not understand well the descriptions of pins in/(& between datasheet) instructions for U8G2
(sorry for my poor English)
