GC9X01X display driver.
|
|
|
|
This driver implements support for various GC9X01X graphics
|
|
controllers and different display sizes. It has been validated
|
|
for following controllers:
|
|
- GC9101A: (Waveshare 240x240, 1.28inch round lcd display 240x240)
|
|
|
|
Here is an example to define a display interface:
|
|
|
|
&spi2 {
|
|
gc9a01a_lcd: gc9a01a_lcd@0 {
|
|
compatible = "galaxycore,gc9x01x";
|
|
reg = <0>;
|
|
spi-max-frequency = <100000000>;
|
|
cmd-data-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>;
|
|
reset-gpios = <&gpio0 8 GPIO_ACTIVE_LOW>;
|
|
pixel-format = <PANEL_PIXEL_FORMAT_RGB_565>;
|
|
width = <240>;
|
|
height = <240>;
|
|
};
|
|
};
|
|
|
|
|
|
compatible: "galaxycore,gc9x01x"
