Arduino TFT屏模擬LED仿真

ID:275826 · 發表于 2019-9-22 19:13

ARDUINO板外面接線很麻煩，我用TFT屏模擬LED可以實現程序仿真，對初學者很有用

單片機源程序如下:

#include <Adafruit_GFX.h>
#include <MCUFRIEND_kbv.h>
#include <TouchScreen.h>
//#include<TimerOne.h>
#include<TimerThree.h>
#if defined(_GFXFONT_H_) //are we using the new library?
#include <Fonts/FreeSans9pt7b.h>
#define ADJ_BASELINE 11 //new fonts setCursor to bottom of letter
#else
#define ADJ_BASELINE 0 //legacy setCursor to top of letter
#endif
MCUFRIEND_kbv tft;
#define YP A1 // must be an analog pin, use "An" notation!
#define XM A2 // must be an analog pin, use "An" notation!
#define YM 7 // can be a digital pin
#define XP 6 // can be a digital pin
#define LCD_CS A3
#define LCD_CD A2
#define LCD_WR A1
#define LCD_RD A0
#define LCD_RESET A4
#define TS_MINX 150
#define TS_MINY 120
#define TS_MAXX 920
#define TS_MAXY 940
/*______End of Calibration______*/
TouchScreen ts = TouchScreen(XP, YP, XM, YM, 300); //300 is the sensitivity
#define BLACK 0x0000
#define BLUE 0x001F
#define RED 0xF800

#define CYAN 0x07FF

#define YELLOW 0xFFE0
#define WHITE 0xFFFF
#define RGB(r, g, b) (((r&0xF8)<<8)|((g&0xFC)<<3)|(b>>3))
#define GREY RGB(127, 127, 127)
#define DARKGREY RGB(64, 64, 64)

#define PURPLE RGB(128, 0, 128)
