打开Arduino IDE,依次打开 工具 -> 管理库… 在搜索框输入需要安装的库名称,找到对应的库,点击安装即可。 本文需要使用的Arduino库如下: 关于LCD驱动的库其实有很多,之所以用TFT_eSPI是因为这个库比较通用,支持很多驱动IC,而且有些图形库也依赖于这个库。不过这个库也有缺点,就是有些配置只能在底层定义不能在应用层...

I have a very basic calculator (Sharp Elsi Mate EL-376S) with a 7-segment LCD. Is it possible to read the values from the calculator's chip and write them to another LCD? (both read and write with an arduino or any micro controller) The "new" display would be detached. Letter/...
