Question

我正在使用带有c控制可编程图形显示器的Arduino UNO。我使用了Franzis Maker Kit Grafikdisplays programmieren的文档，开启了您的创造力。

显示：DXDCG12864-4330 Displaycontroller：ST7564

我的代码是：

#include "TextDisplay.h"

int i=1;
TextDisplay display = TextDisplay();

void setup() {
  display.init(25);
}

void loop() {

char buffer[40];
  display.clear();
  display.println("ABCD");
  sprintf(buffer, "  Dw2: %05d", i);
  display.println(buffer);
  delay(2000);
  i++;
}

问题在于线条相互打印并且display.clear（）不会清除显示。显示2个循环后显示：

ABCD
Dw2: 1
ABCD
Dw2: 2

瞬间：

ABCD
Dw2: 2
