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. |
|
|
|
