Matrix.drawLine()

Matrix. drawLine(x,y,x1,y1) 描述 通过两个点画一条线段。 参数 x：起点横坐标x y：起点横坐标x x1: 终点坐标x1 y1: 终点坐标y1 返回值 无 示例 彩色点阵：Sensor-Dot Matrix-Color/zh #include <Microduino_Matrix.h> uint8_t Addr[MatrixPix_X][MatrixPix_Y] = { //1x1 {64} //点阵IIC地址 }; Matrix display = Matrix(Addr, TYPE_COLOR); //TYPE_COLOR or TYPE_S2 void setup() { Wire.begin(); display.setBrightness(255); } void loop() { //画线，起点坐标x,y 终点坐标x1,y1 display.setColor(255, 0, 0); display.drawLine(0, 0, 7, 7); //x,y,x1,y1 delay(2000); display.clearDisplay(); display.setColor(0, 255, 0); display.drawLine(7, 0, 0, 7); //x,y,x1,y1 delay(2000); display.clearDisplay(); } 单色点阵：Sensor-Dot Matrix-S2/zh #include <Microduino_Matrix.h> uint8_t Addr[MatrixPix_X][MatrixPix_Y] = { //1x1 {64} //点阵IIC地址 }; Matrix display = Matrix(Addr, TYPE_S2); //TYPE_COLOR or TYPE_S2 void setup() { Wire.begin(); display.setBrightness(255); } void loop() { //画线，起点坐标x,y 终点坐标x1,y1 display.drawLine(0, 0, 7, 7); //x,y,x1,y1 delay(2000); display.clearDisplay(); display.drawLine(7, 0, 0, 7); //x,y,x1,y1 delay(2000); display.clearDisplay(); } 其他 setBrightness() setLed() getHeight() getWidth() clearDisplay() drawLine() drawBox() drawRBox() drawFrame() drawRFrame() drawCircle() drawDisc() print() writeString() drawBMP()
