The reference to 37 sensors and actuators has been widely circulated on the Internet. In fact, there must be more than 37 sensor modules compatible with Arduino. In view of the fact that I have accumulated some sensor and actuator modules on hand, according to the concept of practice to get true knowledge (must be done), for the purpose of learning and communication, I am going to try a series of experiments one by one, regardless of success (the program goes through) or not, They will be recorded - small progress or unsolvable problems, hoping to inspire others.
[Arduino] 168 sensor module series experiments (data code + simulation programming + graphics programming)
Experiment 156: 2.4-inch TFT LCD touch screen color screen module TFT-LCD high-definition true color display
Adafruit_TFLCD library related functions
class Adafruit_TFTLCD : public Adafruit_GFX {
public:
Adafruit_TFTLCD(uint8_t cs, uint8_t cd, uint8_t wr, uint8_t rd, uint8_t rst);
Adafruit_TFTLCD(void);
void begin(uint16_t id = 0x9325);
void drawPixel(int16_t x, int16_t y, uint16_t color);
void drawFastHLine(int16_t x0, int16_t y0, int16_t w, uint16_t color);
void drawFastVLine(int16_t x0, int16_t y0, int16_t h, uint16_t color);
void fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t c);
void fillScreen(uint16_t color);
void reset(void);
void setRegisters8(uint8_t *ptr, uint8_t n);
void setRegisters16(uint16_t *ptr, uint8_t n);
void setRotation(uint8_t x);
void setAddrWindow(int x1, int y1, int x2, int y2);
void pushColors(uint16_t *data, uint8_t len, boolean first);
uint16_t color565(uint8_t r, uint8_t g, uint8_t b),
readPixel(int16_t x, int16_t y), readID(void);
uint32_t readReg(uint8_t r);
private:
void init(),
1. Create an object
Adafruit_TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);
void setup(void) {
tft.reset();
tft.begin(0x9341);
}
First, create an Adafruit_TFLCD object named tft, and the pin definition is omitted here.
0x9341 in the begin method means to change the driver of TFT LCD to ILI9341, and others will not be introduced here
2. Screen
void fillScreen(uint16_t color);
uint16_t width(); //屏幕的宽度
uint16_t height(); //屏幕的高度
The full screen is filled with the color color, and the previously displayed content will be blocked again
the case
tft.fillScreen(BLACK);
delay(1000);
tft.fillScreen(RED);
delay(1000);
tft.fillScreen(BLUE);
delay(1000);
3 points
void drawPixel(int16_t x, int16_t y, uint16_t color);
copy code
Draw a pixel with color color on the point (x, y).
the case
tft.drawPixel(1,1,RED);
tft.drawPixel(10,10,RED);
tft.drawPixel(20,20,RED);
tft.drawPixel(40,40,RED);
tft.drawPixel(60,60,RED);
4. Line
void drawLine(int16_t x0, int16_t y0, int16_t x1, int16_t y1, uint16_t color);
void drawFastHLine(int16_t x0, int16_t y0, int16_t w, uint16_t color);
void drawFastVLine(int16_t x0, int16_t y0, int16_t h, uint16_t color);
The simplest is two points to determine a straight line, of course, you can also determine a point, direction, length, the last two are to draw a horizontal line or a plumb line.
the case
tft.drawFastHLine(10,10,170,RED);
tft.drawFastVLine(10,10,170,RED);
tft.drawLine(10,10,100,180,RED);
5. Rectangle && rounded rectangle
void drawRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t c);
void fillRect(int16_t x, int16_t y, int16_t w, int16_t h, uint16_t c);
void drawRoundRect(int16_t x, int16_t y, int16_t w, int16_t h, int16_t radius, uint16_t color);
void fillRoundRect(int16_t x, int16_t y, int16_t w, int16_t h, int16_t radius, uint16_t color);
The rectangle of drawRect draws the border directly, without filling the inside. If you need to fill the inside with color, you need to use fillRect
The rounded rectangle has one more parameter raduis to set the radius of the rounded corner, whether the fill is the same as above.
the case
tft.drawRect(10,10,150,100,RED);
tft.fillRect(10,120,150,100,RED);
tft.drawRoundRect(10,10,150,100,10,RED);
tft.fillRoundRect(10,120,150,100,10,RED);
6. Round
void drawCircle(uint16_t x0, uint16_t y0, uint16_t r, uint16_t color);
void fillCircle(uint16_t x0, uint16_t y0, uint16_t r, uint16_t color);
This is relatively simple, center coordinates (x0, y0), radius r, color color
the case
tft.drawCircle(100,100,50,WHITE);
tft.fillCircle(100,260,50,BLUE);
7. Triangle
void drawTriangle(uint16_t x0, uint16_t y0, uint16_t x1, uint16_t y1, uint16_t x2, uint16_t y2, uint16_t color);
void fillTriangle(uint16_t x0, uint16_t y0, uint16_t x1, uint16_t y1, uint16_t x2, uint16_t y2, uint16_t color);
A triangle needs to determine three vertices and colors
the case
tft.drawTriangle(10,10,100,15,180,100,GREEN);
tft.fillTriangle(10,110,100,115,180,200,GREEN);
8. Character && English text
void drawChar(uint16_t x, uint16_t y, char c, uint16_t color, uint16_t bg, uint8_t size);
void setCursor(uint16_t x0, uint16_t y0); //字体左上角顶点坐标
void setTextColor(uint16_t color); //字体前景色
void setTextColor(uint16_t color, uint16_t backgroundcolor);//字体前景色与背景色
void setTextSize(uint8_t size); //字体大小放法因子
void setTextWrap(boolean w); //是否自动换行，默认为true，滚动显示设置为false
drawChar can only display a single character, you need to determine the coordinates (x, y) of the upper left corner, the character c, the color color, the foreground color color, the background color bg, the size size, when the size is 1, it means 5 * 8 pixels, when it is 2, it means 10*16
Custom fonts do not support background color, you can draw shapes filled with color before this, such as rounded rectangles
the case
tft.fillScreen(GREEN);
tft.drawChar(150,10,'A',RED,WHITE,5);
tft.setCursor(10,50);
tft.print("AB 3.14"); //默认前景色white、无背景色、大小为1
tft.setCursor(10,80);
tft.setTextSize( 4);
tft.print("AB 3.14");
tft.setCursor(10,115);
tft.setTextColor(RED); //背景色不做设置
tft.setTextSize( 4);
tft.print("AB你好3.141516");
tft.setCursor(10,180);
tft.setTextColor(RED, WHITE);
tft.setTextSize( 4);
tft.setTextWrap(false);
tft.print("AB你好3.141516");
You can see that the default font does not support Chinese, you need to use Chinese and add it later
9. Rotate
void setRotation(uint8_t rotation);
The rotation parameter can be 0, 1, 2 or 3, corresponding to 0, 90, 180 or 270 degrees respectively.
For displays that are part of the Arduino shield, a rotation value of 0 sets the display to portrait (tall) mode, and a rotation value of 2 is also portrait mode. Rotation 1 is landscape mode, and rotation 3 is also landscape mode.
the case
//tft.setRotation(1); //注释和未注释的情况下做对比
tft.fillScreen(GREEN);
tft.drawChar(150,10,'A',RED,WHITE,5);
tft.setCursor(10,50);
tft.print("AB 3.14"); //默认前景色white、无背景色、大小为1
tft.setCursor(10,80);
tft.setTextSize( 4);
tft.print("AB 3.14");
tft.setCursor(10,115);
tft.setTextColor(RED); //背景色不做设置
tft.setTextSize( 4);
tft.print("AB你好3.141516");
tft.setCursor(10,180);
tft.setTextColor(RED, WHITE);
tft.setTextSize( 4);
tft.setTextWrap(false);
tft.print("AB你好3.141516");
