在前文Arduino+ESP32 之 驱动GC9A01圆形LCD(一),我们已经移植好了arduino GFX库, 该库的示例程序内,还有LVGL的示例程序哦。 arduino环境下移植lvgl是很方便的,我们一起来移植一个,并且跑一下lvgl的示例demo!由于arduino的library这个路径内的arduino工程文件是只读的,不便于我们编译测试示例程序,所以我们复制一份lvgl...

其他的工作由FSM(UART controller’s finite state machine)完成 。 具体的使用可以查看手册上面Running UART Communication章节。
Following on from theFTDI + ESP8266post, if you do not have a FTDI serial adaptor you can use an Arduino. Here is how to set up the Arduino to talk to the ESP8266. I an using a 5V Arduino Nano which of course is 5V. The Esp8266 is a 3.3v device and so I am using a voltag...
arduino ide mpu6050的库 操作步骤: 把esp32和mpu60插入面包板,用跳线连接二者,使用i2c通信协议,一共需要四根线,分别是电源正vcc,地gnd,数据sdl和时钟scl。打开arduino ide,在库中搜索mpu6050,然后安装它。第一个库,我的已经安装好了,如下图。打开file-example-mpu6050-mpu6050_raw,有现成的实例代码。由于...

The LED has only two states so simple control codes can be used and to start I am using 1 of on and 0 for off. In these examples I am using Arduino Nanos but any kind of Arduino can be used and for this series I am using Arduino to Arduino communication. The techniques are ...
#include <Arduino.h> // Include the header for the ModbusClient RTU style #include "ModbusClientRTU.h" // Create a ModbusRTU client instance // In my case the RS485 module had auto halfduplex, so no parameter with the DE/RE pin is required! ModbusClientRTU MB; // Define an onData...
In terms of API, it will be very similar to the regular Serial communication functions we use on the Arduino environment. Note that the example provided here is based on the libraryexampleavailable on the Arduino core, which I encourage you to try. ...
