| 12 | description: | |
| 13 | This device can be used as bridge between a host controller and LCD panels. |
| 14 | Currently supported LCDs are: |
| 15 | - LCD-OLinuXino-4.3TS |
| 16 | - LCD-OLinuXino-5 |
| 17 | - LCD-OLinuXino-7 |
| 18 | - LCD-OLinuXino-10 |
| 19 | |
| 20 | The panel itself contains: |
| 21 | - AT24C16C EEPROM holding panel identification and timing requirements |
| 22 | - AR1021 resistive touch screen controller (optional) |
| 23 | - FT5x6 capacitive touch screen controller (optional) |
| 24 | - GT911/GT928 capacitive touch screen controller (optional) |
| 25 | |
| 26 | The above chips share same I2C bus. The EEPROM is factory preprogrammed with |
| 27 | device information (id, serial, etc.) and timing requirements. |
| 28 | |
