器件型号:AM62A3

团队成员您好  

我们正在研究在定制电路板 am62a3上引入 DPI 显示屏(RGB)、并通过 SPI 进行通信。

我按如下方式添加了 DTS 节点:

  • SPI0_CSI
  • SPI0_CLK
  • SPI0_D0
  • SPI0_D1

这些引脚将连接到电路板。 我非常感谢您的团队就下一步行动和需要采取的行动提供指导。

  • &main_spi0{
        #address-cells = <1>;
        #size-cells = <0>;    //  Display
     
        status = "okay";
        pinctrl-names = "default";
        pinctrl-0 = <&main_spi0_pins_default>;
     
        panel@0 {
            compatible = "sitronix,st7789v";
            reg = <0>;
     
            reset-gpios = <&exp2 5 GPIO_ACTIVE_LOW>;
            dc-gpios    = <&exp2 6 GPIO_ACTIVE_HIGH>;
            // led-gpios    = <&gpio pin GPIO_ACTIVE_HIGH>;
            // backlight    = <&pwm>;
            // power-supply = <&power>;
     
            rotate  = <0>   ;
            width   = <320> ;
            height  = <240> ;
            fps     = <60>  ;
            buswidth    = <8>;
            
            spi-max-frequency = <32000000>;
            spi-cpol;
            spi-cpha;
            
            
            port {
    					panel_in: endpoint {
    							remote-endpoint = <&dpi1_out>;
    					};
    			};
        };
    };
    
    
    dpi1_out: endpoint {
                 remote-endpoint = <&panel_in>;
     		};
