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 | II2C clock |
| J24-22 | TOUCH_SDA | II2C 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。
