Scrolling text Arduino example code When you want to print a message on a dot matrix display, you will often find that the display is too small to fit the entire message. The solution is in the MD_Parola library, which makes it super easy to create scrolling text effects. In the followi...
lastScrollTime = currentTime;// 更新滚动位置scrollPosition+=5;// 如果滚动到文本末尾,则重置滚动位置if(scrollPosition > textWidth) { scrollPosition =0; }// 重绘屏幕drawScrollingText(); } }// 绘制滚动文本的函数voiddrawScrollingText(){ u8g2.clearBuffer();// 计算绘制文本的起始 X 坐标(负数表...
绘制滚动文本的函数voiddrawScrollingText(){u8g2.clearBuffer();// 计算绘制文本的起始 X 坐标(负数表示文本部分在屏幕外)int16_txPos=0-scrollPosition;// 绘制文本u8g2.setCursor(xPos,yPos);u8g2.print(longText);u8g2.sendBuffer();} 感觉效果不是很好。 中文分段显示 代码如下: #include<U8g2lib....
