d1s + st7701s RGB颜色异常

[ggy321]

板子上麻雀d1s，显示屏是st7701s，spi+RGB控制的，显示彩条和色阶都没有问题
显示图片和lvgl演示就很怪

屏幕是18bitRGB，disp设置如下

&disp {
	disp_init_enable         = <1>;
	disp_mode                = <0>;

	screen0_output_type      = <1>;
	screen0_output_mode      = <4>;

	screen1_output_type      = <3>;
	screen1_output_mode      = <4>;
	
	screen1_output_format    = <0>;
	screen1_output_bits      = <0>;
	screen1_output_eotf      = <4>;
	screen1_output_cs        = <257>;
	screen1_output_dvi_hdmi  = <2>;
	screen1_output_range     = <2>;
	screen1_output_scan      = <0>;
	screen1_output_aspect_ratio = <8>;
	dev0_output_type         = <1>;
	dev0_output_mode         = <4>;
	dev0_screen_id           = <0>;
	dev0_do_hpd              = <0>;

	dev1_output_type         = <4>;
	dev1_output_mode         = <10>;
	dev1_screen_id           = <1>;
	dev1_do_hpd              = <1>;

	def_output_dev           = <0>;
	hdmi_mode_check          = <1>;
	disp_rotation_used		 = <1>;
	degree0					 = <0>;
	fb0_format               = <0>;
	fb0_buffer_num           = <1>;	
	/*fb0_width                = <800>;*/
	/*fb0_height               = <480>;*/  /*read from lcd*/
	fb1_format               = <0>;
	fb1_width                = <0>;
	fb1_height               = <0>;
	chn_cfg_mode             = <1>;

	disp_para_zone           = <1>;
	/*VCC-LCD*/
/*	dc1sw-supply = <&reg_dc1sw>;*/
	/*VCC-DSI*/
/*	eldo3-supply = <&reg_eldo3>;*/
	/*VCC-PD*/
/*	dcdc1-supply = <&reg_dcdc1>;*/
};

lcd设置如下：

&lcd0 {
	lcd_used            = <1>;
	lcd_driver_name     = "st7701s_3spi";

	lcd_backlight       = <100>;

	lcd_if          	= <0>;
	lcd_hv_if       	= <0>;

	lcd_width       	= <65>;
	lcd_height      	= <130>;
	lcd_x           	= <480>;
	lcd_y           	= <960>;
	lcd_dclk_freq   	= <30>;

	lcd_hbp         	= <15>;
	lcd_ht          	= <512>;
	lcd_hspw        	= <2>;
	lcd_vbp         	= <17>;
	lcd_vt          	= <996>;
	lcd_vspw        	= <2>;

	lcd_pwm_used        = <1>;
	lcd_pwm_ch          = <7>;
	lcd_pwm_freq        = <1000>;
	lcd_pwm_pol         = <0>;
	lcd_pwm_max_limit   = <255>;

	lcd_frm         	= <1>;
	lcd_io_phase    	= <0x0000>;
	lcd_gamma_en    	= <0>;
	lcd_cmap_en     	= <0>;
	lcd_hv_clk_phase	= <0>;
	lcd_hv_sync_polarity= <0>;
	lcd_rb_swap         = <0>;

	deu_mode            = <0>;
	lcdgamma4iep        = <22>;
	smart_color         = <90>;

	lcd_gpio_0 = <&pio PE 8 GPIO_ACTIVE_HIGH>;   // RST
	lcd_gpio_1 = <&pio PE 9 GPIO_ACTIVE_HIGH>;   // CS
	lcd_gpio_2 = <&pio PE 7 GPIO_ACTIVE_HIGH>;   // SDA
	lcd_gpio_3 = <&pio PE 6 GPIO_ACTIVE_HIGH>;   // SCK
	pinctrl-0 = <&rgb18_pins_a>;
	pinctrl-1 = <&rgb18_pins_b>;
};

屏幕的初始化代码和屏参都是卖家提供，rgb抖动开0、1、2都不正常，请大佬指点是哪里的问题！感谢！

@ggy321 大哥，这个问题解决了没呢，我也遇到了一样的问题，图片显示有波纹，感觉像颜色错开了一样。

@ggy321 在 d1s + st7701s RGB颜色异常 中说：

lcd_frm = <1>;这个配置要看你的屏驱动配置的是多少bit位宽的数据，如果配置不正确就是你看到的这样。过渡不平滑
