最近玩Arduino时,有一块ILI9486错都LCD屏,它没有局部刷新功能,所以就把背景设置为黑色,然后用变量记住光标的位置,用设置文字颜色为黑色的方法在原位置重新显示相同的字符,这样旧的数据就消失了,然后再改文字的颜色为绿色重新显示新的值。效果不错,完全满足局部刷新 的效果,分享给大家。希望可以帮助到你。 #include<...

The wiring diagram below shows you how to connect the MAX7219 LED dot matrix display to the Arduino.Note that when using the MD_Parola library, you need to orient the display with the DIN connector on the right, otherwise the text will be printed upside down.For more information seethe sect...
LCD displays typically operate at 5V, however, some displays may require a different voltage, so it’s important to check the specifications of your particular display. Some LCD displays come with a built-in backlight, which can consume a significant amount of power. ...
3、实验用的LCD驱动芯片为ST7735S,查找阅读相关的Arduino函数库; 4、移植函数库到RPI Pico上; 5、将ST7735S彩屏用到自己的项目中。 显示屏连接要点 #define TFT_CS 22 #define TFT_RST 7 // Or set to -1 and connect to Arduino RESET pin
LCD屏幕的发光原理主要依靠背光层,背光层发出白光,背光层上有一层有颜色的薄膜,透过薄膜之后就能显示出彩色,在背光层和颜色薄膜之间液晶层,调整红蓝绿的比例。 这个RGB的比例,有多种表达方式,常见的有RGB555、RGB565、RGB24和RGB32。 RGB24使用24位来表示一个像素,RGB分量都用8位表示,取值范围为0-255。注意在内...
