[自用]arduino框架下TFT屏幕 和 LVGL 配置代码
段干子晋
// 用户定义设置
// 设置驱动程序类型、要加载的字体、使用的引脚和SPI控制方法等
//
// 如果希望能够定义多个设置，然后轻松选择编译器使用的安装文件。
// 看文件User_Setup_Select.h
//
// 如果此文件编辑正确，则所有库示例程序都能运行，而无需对特定硬件设置进行任何更改！
// 注意，有些程序是为特定的TFT像素宽度/高度设计的

// 第二节.在此处定义用于与显示屏接口的引脚
//
// ##################################################################################
// 我们必须使用硬件SPI，至少需要3个GPIO引脚。
// ESP8266 NodeMCU ESP-12的典型设置为：
//
// Display SDO/MISO to NodeMCU pin D6 (or leave disconnected if not reading TFT)
// Display LED to NodeMCU pin VIN (or 5V, see below)
// Display SCK to NodeMCU pin D5
// Display SDI/MOSI to NodeMCU pin D7
// Display DC (RS/AO)to NodeMCU pin D3
// Display RESET to NodeMCU pin D4 (or RST, see below)
// Display CS to NodeMCU pin D8 (or GND, see below)
// Display GND to NodeMCU pin GND (0V)
// Display VCC to NodeMCU 5V or 3.3V
//
// TFT复位引脚可以连接到NodeMCU RST引脚或3.3V以释放控制引脚
//
// DC（Data Command数据命令）引脚可以标记为AO或RS（寄存器选择）
//
// 对于某些显示屏，如ILI9341，如果没有更多的SPI设备（如SD卡）连接，
// TFT CS引脚可以连接到GND，在这种情况下，请注释下面的“定义TFT CS”行，
// 以便不定义它。在ST7735上的其他显示屏需要在设置期间切换TFT-CS引脚，
// 因此在这些情况下，必须定义和连接TFT-CS线。
//
// NodeMCU D0 pin可用于RST
//
//
// 注意：只有部分版本的NodeMCU在VIN引脚上提供了USB 5V，
// 如果引脚上没有5V，则可以使用3.3V，但背光亮度会更低。
// ###### 编辑以下行中的引脚号以适合您的ESP8266设置 ######
// 对于NodeMCU-使用pin_Dx形式的引脚号，其中Dx是NodeMCU引脚名称
//#define TFT_CS PIN_D8 // Chip select control pin D8
//#define TFT_DC PIN_D3 // Data Command control pin
//#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
//#define TFT_BL PIN_D1 // LED back-light (only for ST7789 with backlight control pin)
//#define TOUCH_CS PIN_D2 // Chip select pin (T_CS) of touch screen
//#define TFT_WR PIN_D2 // Write strobe for modified Raspberry Pi TFT only
// ###### 对于ESP8266重叠模式，编辑以下行中的引脚号 ######
// 重叠模式与TFT共享ESP8266闪存SPI总线，因此对性能有影响，但为其他功能保存引脚。
// 最好不要连接MISO，因为当芯片选择引脚为高电平时，某些显示屏不会三态显示该行！
// 在NodeMCU 1.0上，SD0=MISO，SD1=MOSI，CLK=SCLK 以重叠模式连接到TFT
// 在NodeMCU V3上， S0=MISO，S1=MOSI，S2=SCLK
// 在ESP8266重叠模式下，必须定义以下内容
//#define TFT_SPI_OVERLAP
// 在ESP8266重叠模式下，TFT芯片选择必须连接到引脚D3
//#define TFT_CS PIN_D3
//#define TFT_DC PIN_D5 // Data Command control pin
//#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
// ###### 编辑以下行中的引脚号以适合您的ESP32设置 ######
// 用于ESP32开发板（仅用ILI9341显示屏测试）
// 硬件SPI可以映射到任何引脚
// 我把背光引脚LED接到了3.3V上，常亮了
#define TFT_MISO 12

#define TOUCH_CS 21 // 触摸屏的芯片选择引脚 (T_CS)，
//#define TFT_WR 22 // 仅适用于改性树莓派TFT的写入选通 Write strobe for modified Raspberry Pi TFT only
// 对于M5Stack模块，使用以下定义行
//#define TFT_MISO 19
//#define TFT_MOSI 23
//#define TFT_SCLK 18
//#define TFT_CS 14 // Chip select control pin
//#define TFT_DC 27 // Data Command control pin
//#define TFT_RST 33 // Reset pin (could connect to Arduino RESET pin)
//#define TFT_BL 32 // LED back-light (required for M5Stack)
// ###### 编辑下面的引脚以适合您的ESP32并行TFT设置 ######
// 库支持ESP32的8位并行TFT，下面的引脚选择与UNO格式的ESP32板兼容。
// 需要修改Wemos D32板，请参阅“工具”文件夹中的图表。
// 只测试了基于ILI9481和ILI9341的显示器！
// 仅ESP32支持并行总线
// 取消下面的注释行以使用ESP32并行接口而不是SPI
//#define ESP32_PARALLEL
// 用于测试的ESP32和TFT引脚为：
//#define TFT_CS 33 // Chip select control pin (library pulls permanently low
//#define TFT_DC 15 // Data Command control pin - must use a pin in the range 0-31
//#define TFT_RST 32 // Reset pin, toggles on startup
//#define TFT_WR 4 // Write strobe control pin - must use a pin in the range 0-31
//#define TFT_RD 2 // Read strobe control pin
//#define TFT_D0 12 // Must use pins in the range 0-31 for the data bus
//#define TFT_D1 13 // so a single register write sets/clears all bits.
//#define TFT_D2 26 // Pins can be randomly assigned, this does not affect
//#define TFT_D3 25 // TFT screen update performance.
//#define TFT_D4 17
//#define TFT_D5 16
//#define TFT_D6 27
//#define TFT_D7 14

//

// ESP8366和ESP32有足够的内存，因此通常不需要注释字体。
// 如果加载了所有字体，则所需的额外闪存空间约为17Kbytes。
// 为了节省内存空间，只启用您需要的字体！
#define LOAD_GLCD // 字体 1. 原来的Adafruit 8像素字体需要约1820字节的FLASH

#define LOAD_FONT7 // 字体 7. 7段48像素字体，FLASH需要约2438字节，仅字符1234567890:-.
#define LOAD_FONT8 // 字体 8. 75像素的大字体在FLASH中需要3256字节，只有1234567890个字符:-.
//#define LOAD_FONT8N // 字体 8. 上面字体8的替代品，稍微窄一些，因此3位数字适合160像素的TFT
#define LOAD_GFXFF // 自由字体. 包括访问48个Adafruit_GFX免费字体FF1到FF48和自定义字体
// 注释掉下面的定义，以停止SPIFFS文件系统并平滑加载字体代码
// 这将节约 ~20kbytes of flash

// 定义SPI时钟频率，这会影响图形渲染速度。速度太快，TFT驱动程序无法跟上，显示不正确。
// 对于ILI9341显示屏，40MHz工作正常，80MHz有时出现故障
// 对于ST7735显示屏，超过27MHz可能无法工作（杂散像素和线）
// 对于ILI9163显示屏，27MHz工作正常。

// XPT2046（触摸屏驱动库）需要2.5MHz的较低SPI时钟速率，因此我们在此定义：
#define SPI_TOUCH_FREQUENCY 2500000
// ESP32有两个空闲的SPI端口，即VSPI和HSPI，VSPI是默认端口。
// 如果VSPI端口正在使用中，并且无法访问管脚（例如TTGO T-Beam）
// VSPI: CS->5 SCLK->18 MISO->19 MOSI->23
// HSPI: CS->15 SCLK->14 MISO->12 MOSI->13
// 则取消注释以下行:
// 重要：如果触摸屏要独立使用XPT2046_TouchScreen驱动，下面这行一定要取消注释，2天的工夫找到这行
//#define USE_HSPI_PORT
// 如果不需要支持“SPI事务”，请注释掉以下定义。
// 当被注释掉，代码大小会变小，程序运行得稍微快一点，
// 所以除非你需要，否则就不要注释
// 使用SD库需要事务支持，但不需要TFT-SdFat
// 如果连接了其他SPI设备，则需要事务支持。
// 库为ESP32自动启用事务（使用HAL互斥）
// 所以在这里改变它没有效果
