全志T113 接LVDS 屏幕

[daMing123]

用了MQ-r的板子，接上LVDS屏幕
把LCD的引脚引出来，淘宝买了一个40Pin排线，把2.54mm针的距离引出来

然后查看原理图，查看board.dts，查看引脚，接上
由于LVDS屏幕需要一个正负电压，查看规格书，

VGH 18V，VGL -10V，手头没有，于是淘宝找了一个LVDS电压转接板，把负电压，正电压，升压得到合适的电压，下面是升级板

接上屏幕，另外一边接转接板。修改dts文件如下
&lcd0 {
lcd_used = <1>;

lcd_driver_name     = "default_lcd";
lcd_if              = <3>;

lcd_x               = <1024>;
lcd_y               = <600>;
lcd_width           = <150>;
lcd_height          = <94>;
lcd_dclk_freq       = <51>;

lcd_pwm_used        = <0>;

lcd_hbp             = <80>;
lcd_ht              = <1344>;
lcd_hspw            = <20>;
lcd_vbp             = <10>;
lcd_vt              = <635>;
lcd_vspw            = <10>;

lcd_lvds_if         = <0>;
lcd_lvds_colordepth = <1>;
lcd_lvds_mode       = <1>;

lcd_frm             = <1>;
lcd_hv_clk_phase    = <0>;
lcd_hv_sync_polarity= <0>;
lcd_gamma_en        = <0>;
lcd_bright_curve_en = <0>;
lcd_cmap_en         = <0>;

pinctrl-0 = <&lvds0_pins_a>;
pinctrl-1 = <&lvds0_pins_b>;

};
最后上电，成功点亮

完成，走了很多弯路，因为对LVDS不了解，淘宝买东西耽搁几天时间。大家可以对照着来，如果用到LVDS的话。
