楼主
各位大神,
我有一片 360x360 1.5” 圆形 LCD , IC:NT35350使用 MIPI 1 对数据线(C+/C-、D0+/D0-) DataRate: 230Mbps 怎么搞画面都只有一半颜色也不正确, 求解!
disp_mipi_init: mipi_dsi_init{
compatible = "rockchip,mipi_dsi_init";
rockchip,screen_init = <1>;
rockchip,dsi_lane = <1>;
rockchip,dsi_hs_clk = <230>;
rockchip,mipi_dsi_num = <1>;
};
disp_mipi_init_cmds: screen-on-cmds {
rockchip,cmd_debug = <0>;
compatible = "rockchip,screen-on-cmds";
rockchip,on-cmds01 {
compatible = "rockchip,on-cmds";
rockchip,cmd_type = <LPDT>;
rockchip,dsi_id = <0>;
rockchip,cmd = <0x15 0xFF 0x10>;
rockchip,cmd_delay = <0>;
};
rockchip,on-cmds02 {
compatible = "rockchip,on-cmds";
rockchip,cmd_type = <LPDT>;
rockchip,dsi_id = <0>;
rockchip,cmd = <0x15 0xBB 0x03>;
rockchip,cmd_delay = <0>;
};
rockchip,on-cmds03 {
compatible = "rockchip,on-cmds";
rockchip,cmd_type = <LPDT>;
rockchip,dsi_id = <0>;
rockchip,cmd = <0x05 0x11>;
rockchip,cmd_delay = <150>;
};
rockchip,on-cmds04 {

};
};
