Arduino 開發範例

2024/1/7

我把目前使用的 Arduino ide 1.8.19 可攜版環境打包成一個檔案，已包含常用的 library

方便用來開發 Pico_Game 相關程式

file : arduino-1.8.19_picogame.zip ，建議在根目錄下解開，大小約 1G

使用 Arduino 開發時，會建議使用 TFT_eSPI 的 library 來驅動 SPI 的螢幕

(此檔定義相關的腳位)

內容如下:

// Only define one driver, the other ones must be commented out

#define ILI9341_DRIVER

// For the Pico use these #define lines

#define TFT_MISO 16

#define TFT_MOSI 19

#define TFT_SCLK 18

#define TFT_CS 17 // Chip select control pin

#define TFT_DC 20 // Data Command control pin

#define TFT_RST 21 // Reset pin (could connect to Arduino RESET pin)

//#define TFT_BL // LED back-light

#define LOAD_GLCD // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH

#define LOAD_FONT2 // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters

#define LOAD_FONT4 // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters

#define LOAD_FONT6 // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm

#define LOAD_FONT7 // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:-.

#define LOAD_FONT8 // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.

//#define LOAD_FONT8N // Font 8. Alternative to Font 8 above, slightly narrower, so 3 digits fit a 160 pixel TFT

#define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

// Comment out the #define below to stop the SPIFFS filing system and smooth font code being loaded

// this will save ~20kbytes of FLASH

#define SMOOTH_FONT

#define SPI_FREQUENCY 70000000

// Optional reduced SPI frequency for reading TFT

#define SPI_READ_FREQUENCY 20000000

// The XPT2046 requires a lower SPI clock rate of 2.5MHz so we define that here:

#define SPI_TOUCH_FREQUENCY 2500000

3. Library 目錄下，修改 User_Setup_Select.h 內容，選擇上面新增的定義檔
