socket.sendto(bytes, address)¶ 将数据发送到socket。Socket不应连接到远程socket,因为目的地socket由 address 指定。 socket.recvfrom(bufsize)¶ 从socket上接收数据。返回值是两个数值(bytes, address),其中bytes是一个表示接收到的数据的字节对象,address是发送数据的socket地址。 socket.setsockopt(level, optn...
In this tutorial, we will learn to use the MPU-6050 MEMS module with ESP32 and ESP8266 to measure accelerometer, gyroscope, and temperature values using MicroPython firmware. Firstly, we will see an introduction of MPU6050 such as pinout diagram, pin configuration. Secondly, we will see how t...

Behind the scences these objects implement the buffer protocol to give access to the function pointer bytes. Starting from version 6.0, lvgl supports setting the display settings (width, length) on runtime. In this example they are set to 480x320. Color depth is set on compile time. ...
If you would like to use the Pybytes IoT platform, head to thePybytes site, make an account, and copy in the activation key when asked. Otherwise, feel free to skip that step (the firmware will install regardless of whether you provided a Pybytes key or not). ...
