Display: http://www.tme.eu/en/details/rx240128a-ghw/lcd-graphic-displays/raystar-optronics/
|
||
|
Connection: HW / SW SPI.
|
||
|
To get this display working, You need some extra capacitors:
|
||
|
|
||
|
connect 4.7uF caps between:
|
||
|
PIN1 & PIN2 VB1 +-
|
||
|
PIN3 & PIN4 VB0 -+
|
||
|
connect 0.1uF caps between:
|
||
|
VLCD and VSS
|
||
|
VBIAS and VSS
|
||
|
You can find some schematics with a 10M resistor parallellized with the VLCD capacitor.
|
||
|
|
||
|
Select 4-bit SPI mode.
|
||
|
|
||
|
Connect D7 (PIN9) To VDD (+3.3V)
|
||
|
Connect D1, D2, D4, D5, D6 to GND (PINS 10,11,12,14,15)
|
||
|
Connect WR0, WR1, BM0, BM1 to GND (PINS 17,18,22,23)
|
||
|
|
||
|
D0: (PIN16) AVR's SCK pin (HW SPI)
|
||
|
D3: (PIN13) AVR's MOSI pin (HW SPI)
|
||
|
CD: (PIN19) used as A0 in the library
|
||
|
CS: (PIN21) Connect to the defined CS pin, and You can re-use the HW SPI in different routines.
|
||
|
RST: (PIN20) optional reset, can be defined in the function, resets on initialization.
|
||
|
|
||
|
Adjust contrast if necessary. Default: 0x072.
