Matrix.drawCircle()

Matrix. drawCircle(x,y,r) 描述 画空心圆。 参数 x：起点横坐标x y：起点横坐标x r：半径 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); display.clearDisplay(); } void loop() { //画空心圆，圆心x,y 半径r display.setColor(255, 0, 255); display.drawCircle(3, 3, 3); //x,y,r delay(2000); display.clearDisplay(); display.setColor(0, 255, 255); display.drawCircle(3, 3, 2); //x,y,r 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); display.clearDisplay(); } void loop() { //画空心圆，圆心x,y 半径r display.drawCircle(3, 3, 3); //x,y,r delay(2000); display.clearDisplay(); display.drawCircle(3, 3, 2); //x,y,r delay(2000); display.clearDisplay(); } 其他 setBrightness() setLed() getHeight() getWidth() clearDisplay() setColor() drawLine() drawRBox() drawFrame() drawRFrame() drawDisc() print() writeString() drawBMP()
