触摸屏配置

显示部分

SPI配置
  1. SPI1_PLATFORM_DATA_BEGIN(spi1_data)
  2.     .clk    = 96000000,
  3.     .mode   = SPI_1WIRE_MODE,
  4.     .port   = 'B',
  5.     .attr   =  SPI_SCLK_L_UPL_SMPH | SPI_UNIDIR_MODE,//主机，CLK低 更新数据低，单向模式
  6. SPI1_PLATFORM_DATA_END()

接口定义
  1. static const struct ui_lcd_platform_data pdata = {
  2.     .spi_id  = "spi1",
  3.     .bl_pin = IO_PORTH_02,
  4.     .cs_pin  = IO_PORTH_03,
  5.     .rs_pin  = IO_PORTH_04,
  6.     .rst_pin = IO_PORTH_05,
  8.        .touch_reset_pin = IO_PORTH_06,
  9.        .touch_int_pin = IO_PORTH_07,
  10.     .te_pin  = -1,
  11.     .lcd_if  = LCD_SPI,//屏幕接口类型还有 PAP , SPI
  12. };

配置完成之后，记得要检查REGISTER_DEVICES(device_table)中有没有配置，app_config.h中有没有启用

在lcd_drive.c的第343行添加如下代码

  1. #if TCFG_LCD_ST7789V_ENABLE//客户屏放最后
  2.         lcd_w = 240;
  3.         lcd_h = 280;
  4.         lcd_bk_on = 1;
  5.         lcd_bk_off = 0;
  6.         lcd_choice = CONFIG_ST7789V_ID;
  7.         printf("\n [lcd_drive] %s -[find_check_ST7789] %d\n", __FUNCTION__, __LINE__);
  8. #endif

触摸部分

iic配置
  1. #ifdef CONFIG_IIC_ENABLE
  2. HW_IIC0_PLATFORM_DATA_BEGIN(hw_iic1_data)//硬件IIC
  3.     .clk_pin = IO_PORTH_00,
  4.     .dat_pin = IO_PORTH_01,
  5.     .baudrate = 0x3f,
  6. HW_IIC0_PLATFORM_DATA_END()
  8. SW_IIC_PLATFORM_DATA_BEGIN(sw_iic0_data)//软件iic
  9.     .clk_pin = IO_PORTH_00,
  10.     .dat_pin = IO_PORTH_01,
  11.     .sw_iic_delay = 50,
  12. SW_IIC_PLATFORM_DATA_END()
  13. #endif

配置完成之后，记得要检查REGISTER_DEVICES(device_table)中有没有配置，app_config.h中有没有启用

替换驱动文件

lcd_st7789v.c
cst816t.c
lcd_drive.h
lcd_drive.c

需要修改ui/include/lcd_config.h

  1. #define LCD_W 240
  2. #define LCD_H 280

app_config.h配置

里面有非常多的宏定义，根据这些宏定义，开关相应的功能

  1. #define TCFG_LCD_ST7789V_ENABLE     1
  2. #define TCFG_TOUCH_CST816T_ENABLE   1
  3. #define USE_LVGL_UI_DEMO            1
  4. #define CONFIG_UI_ENABLE            1
  5. #define CONFIG_BT_ENABLE            1

注意将没有用到的UI配置全都禁用掉

  2. #define USE_LCD_240X320                           0
  3. #define USE_LCD_320X480                           0
  6. #if USE_LCD_240X320
  7. #define TCFG_TOUCH_GT911_ENABLE                   0
  8. #define TCFG_LCD_ILI9341_ENABLE                      0
  9. #endif //USE_LCD_240X320_ILI9341
  11. #if USE_LCD_320X480
  12. #define TCFG_TOUCH_FT6236_ENABLE                  0
  13. #define TCFG_LCD_ILI9488_ENABLE                      0
  14. #define TCFG_LCD_ILI9481_ENABLE                      0
  15. #endif //USE_LCD_320X480_ILI9481

其它配置

  1. 禁用ui_main.c
  2. wifi_demo_task.c 文件注释掉568行的 //stats_display();
