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...
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...

mpy-cross/ -- the MicroPython cross-compiler which is used to turn scripts into precompiled bytecode. ports/unix/ -- a version of MicroPython that runs on Unix. ports/stm32/ -- a version of MicroPython that runs on the PyBoard and similar STM32 boards (using ST's Cube HAL drivers). ...
read(5) # read up to 5 bytes 有两个 UART 可用。UART0 位于引脚 1 (TX) 和 3 (RX) 上。UART0 是双向的,默认情况下用于 REPL。UART1 位于引脚 2 (TX) 和 8 (RX) 上,但引脚 8 用于连接闪存芯片,因此 UART1 仅用作 TX。 当UART0 连接到 REPL 时,UART(0) 上的所有传入字符都会直接进入 ...
