Serial.println(number); will print this: 1 In the example sketch, the number printed will be 0 when the loop starts and will increase by one each time through the loop. The ln at the end of println causes the n

如果使用的是简约版不带TTL转串口芯片的板子,还需要开启下图所示的USB CDC,此时使用Serial输出的数据便可以显示。 或者不嫌麻烦的可以改下代码,把数据显示在屏幕上。 得到串口输出的触摸校准参数,TFT-eSPI这一块就结束了,LVGL不需要TFT-eSPI的其它功能,只是把它作为了一个屏幕显示的工具,毕竟主控种类、屏幕驱动种类...
