变成了这样了,

这种孔板子中间出线，想修估计都修不好了。

I2C0_SCL, I2C0_SDA (PB6, PB7)彻底阵亡了

把 I2C1 强行怼上去试一试

晕哥 · 2019-05-31 09:22:29

这样怼上去之后，触摸屏是使用是 I2C1 (PE21, PE22) 了。

接下来修改设备树:

sun8i-v3s.dtsi

i2c1_pins: i2c1 {
pins = "PE21", "PE22";
function = "i2c1";
};

i2c1: i2c@01c2b000 {
compatible = "allwinner,sun6i-a31-i2c";
reg = <0x01c2b000 0x400>;
interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&ccu CLK_BUS_I2C1>;
resets = <&ccu RST_BUS_I2C1>;
pinctrl-names = "default";
pinctrl-0 = <&i2c1_pins>;
status = "disabled";
#address-cells = <1>;
#size-cells = <0>;
};

arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts

&i2c1 {
status = "okay";

ft6x06@38 {
compatible = "focaltech,ft6236";
reg = <0x38>;
interrupt-parent = <&pio>;
interrupts = <1 4 IRQ_TYPE_EDGE_FALLING>;
reset-gpios = <&pio 4 23 GPIO_ACTIVE_LOW>;
touchscreen-size-x = <480>;
touchscreen-size-y = <854>;
touchscreen-inverted-x;
touchscreen-swapped-x-y;
};
};

驱动配置开启:

CONFIG_TOUCHSCREEN_EDT_FT5X06=y
