Arduino 是一个电子原型平台,有各种各样的arduino开发板,也有用来写代码的arduino IDE软件,该软件提供类似Java、C语言的Processing/Wiring开发环境。只要在IDE中编写程序代码,编译成二进制文件,将程序上传到Arduino电路板后,烧录进微控制器,程序便会告诉Arduino电路板要做些什么了。 Arduino 可以通过
我们需要用到以下几个库文件：Adafruit GFX库、Adafruit TouchScreen库和Adafruit TFT LCD库。TFTLCD库...
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<...
// SPI speed defaults to SPI_DEFAULT_FREQ defined in the library, you can override it here // Note that speed allowable depends on chip and quality of wiring, if you go too fast, you // may end up with a black screen some times, or all the time. //tft.setSPISpeed(40000000); Se...
