试试哪吒MQ运行lvgl 60帧率触控效果

[mangogeek]

遇到点小插曲，由于厂家那边给GT911固化错了配置（把800480分辨率搞成了1024600），所以找厂家要了一份正确配置，需要ctp驱动中开启自动更新配置。

另外，tina linux驱动文件夹gt9xxnew中，分析gtp_init_panel初始化函数。因为手头这个屏幕与文件的都不同，并且看到源文件注释掉了从屏幕读取id。所以可确定sensor_id恒为0，那么就很简单了，自己的配置直接写到gt9xx.h的GOURP1即可。

#if GTP_COMPATIBLE_MODE
		msleep(50);
#endif
//       ret = gtp_i2c_read_dbl_check(ts->client, GTP_REG_SENSOR_ID, &sensor_id, 1);
		dprintk(DEBUG_INIT, "CTP name : %s\n", config_info.name);
		if (!strcmp(config_info.name, "gt9271_mb976a9")) {
			sensor_id = 0;
			dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);

		} else if (!strcmp(config_info.name, "gt9110_wt097")) {
			sensor_id = 1;
			dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);

		} else if (!strcmp(config_info.name, "gt9271_wt097")) {
			sensor_id = 2;
			dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);

		} else if (!strcmp(config_info.name, "gt9110_g200")) {
			sensor_id = 3;
			dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);

		} else if (!strcmp(config_info.name, "gt9271_noah")) {
			sensor_id = 4;
			dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);
		} else if (!strcmp(config_info.name, "gt9271_p2")) {
			sensor_id = 5;

			dprintk(DEBUG_INIT, "gt9xx:sensor_id = %d\n", sensor_id);
		}
		ret = SUCCESS;
		if (SUCCESS == ret) {
			if (sensor_id >= 0x08) {
				printk("Invalid sensor_id(0x%02X), No Config Sent!\n", sensor_id);
				ts->pnl_init_error = 1;

			printk("Failed to get sensor_id, No config sent!\n");
			ts->pnl_init_error = 1;
			return -1;
		}
	}
	ts->gtp_cfg_len = cfg_info_len[sensor_id];
	GTP_INFO( "CTP_CONFIG_GROUP%d used, config length: %d\n", sensor_id + 1, ts->gtp_cfg_len);

效果：

TODO：以后再尝试把group配置放到dts中，会不会更优雅些？
