Interface function
18/24bit LVDS0
- Silk screen：J24
- LVDS0 crystal liquid is 24 bit mode，compatible with 18bit mode，through which LVDS resistance screen panel and LVDS capacitor screen panel in different sizes and specifications produced by MYZR can be cnnected。LVDS0 interface block is build with connector imported，abandon the cheap drawer type produced domestically，which is opposite press type to ensure easier installation,better performance and connectivity.
- Definition of pin & signal as below
| Pin | Singnal | Description |
|---|---|---|
| J24-16 | SD1_DAT1/TOUCH_nEINT1 | GPIO control |
| J24-17 | NANDF_CS3 | GPIO control |
| J24-19 | DISP0_CONTRAST | LVDS0 backlight adjustment |
| J24-21 | TOUCH_SCL | I2C clock |
| J24-22 | TOUCH_SDA | I2C data |
18/24bit RGB
- Silkscreen:J23
- RGB crystal liquid is 24bit mode，compatible to 18bit/16bit mode,through which RGB resistance screen panel and RGB capacitor screen panel in different sizes and specifications produced by MYZR can be cnnected，RGB interface block is build with connector imported，abandon the cheap drawer type produced domestically，which is opposite press type to ensure easier installation,better performance and connectivity。</span>
- Definition of pin & signal：
| Pin | Singnal | Description |
|---|---|---|
| J23-31 | SD1_DAT1/TOUCH_nEINT1 | GPIO control |
| J23-30 | NANDF_CS3 | GPIO control |
| J23-19 | DISP0_CONTRAST | LVDS0 backlight adjustment |
| J23-32 | TOUCH_SCL | I2C clock |
| J23-33 | TOUCH_SDA | I2C data |
18/24bit LVDS1
- Silk screen：J22
- LVDS1 crystal liquid interface is the same as LVDS0 in terms of definition and connector model，users can connect crytal liquid in LVDS0 directly to LVDS1.
- Definition of pin & signal：
| Pin | Singnal | Description |
|---|---|---|
