例如,在我们显示print(1234.56)的地方,你的实际代码会把对象名称放在这之前,例如,它可能会读做screen.print(1234.56)(如果你已经声明了显示对象的名称为:screen)。绘制像素(点) 首先是最基本的像素推送器。你可以调用它,并指定参数:X Y坐标和一种颜色,它会在屏幕上生成一个点:...

The raspi-config screen. Most OS-level options can be set here, including activating and deactivating services. Newer versions of Raspbian automatically expand your file system the first time you start the Pi. Unless you are using an older version of Raspbian, you should be able to skip this...

#define TFT_RST 26 // Reset pin (could connect to RST pin) 四、 代码 在编写程序之前,首先需要对TFT_eSPI这个库中地部分定义更改以适应我的屏幕 ,找到User_Setup.h这个文件打开。 我们需要做如下改动,选择屏幕驱动,这里我的屏幕是ST7789驱动的
Serial.print(X); Serial.print(','); Serial.println(Y);// + " " + Y); 由于我们设计的框的宽度和高度分别为 60 像素,并且有四行和从 (0,0) 开始的列。每个盒子的位置可以预测,如下图所示。 但在实际情况下,结果并非如此。由于校准问题,预期值和实际值之间会有很大的差异。
Adafruit_SSD1306 显示(SCREEN_WIDATA_PINH,SCREEN_HEIGHT,&Wire,-1); AD9833 gen(FNC_PIN); 接下来,我们有我们的setup()函数,在该 setup 函数中,我们首先启用 Serial 进行调试。我们借助begin()方法初始化 AD9833 模块。接下来,我们将所有分配的旋转编码器引脚设置为输入。而我们将时钟引脚的值存储在clockPin...
