description: |
|
||
|
|
This device can be used as bridge between a host controller and LCD panels.
|
||
|
|
Currently supported LCDs are:
|
||
|
|
- LCD-OLinuXino-4.3TS
|
||
|
|
- LCD-OLinuXino-5
|
||
|
|
- LCD-OLinuXino-7
|
||
|
|
- LCD-OLinuXino-10
|
||
|
|
|
||
|
|
The panel itself contains:
|
||
|
|
- AT24C16C EEPROM holding panel identification and timing requirements
|
||
|
|
- AR1021 resistive touch screen controller (optional)
|
||
|
|
- FT5x6 capacitive touch screnn controller (optional)
|
||
|
|
- GT911/GT928 capacitive touch screen controller (optional)
|
||
|
|
|
||
|
|
The above chips share same I2C bus. The EEPROM is factory preprogrammed with
|
||
|
|
device information (id, serial, etc.) and timing requirements.
|
||
