The script itself will handle both making ESP8266/ESP32 as a WiFi access point and hosting an HTML webpage. Once the script is loaded, the board can be secured in a case and deployed within an IoT application intended to run within WLAN.

ESP8266部署MicroPython ESP8266的部署脚本和基础项目结构,带有通过USB仿真的串行端口(例如NodeMCU)。 您可以将部署脚本作为来自PyCharm的运行命令来运行。 部署脚本已在Linux和Windows上进行了测试。. MicroPython ported to Infineon MCUs.

The USB_VCP class allows creation of an object representing the USB virtual comm port. It can be used to read and write data over USB to the connected host. Constructors class pyb.USB_VCP Create a new USB_VCP object. Methods USB_VCP.setinterrupt(chr) Set the character which interrupts running Python code. MicroPython. MicroPython is a lean and efficient implementation of the Python 3 programming language that includes a small subset of the Python standard library and is optimised to run on microcontrollers and in constrained environments. The MicroPython pyboard is a compact electronic circuit board that runs MicroPython on the bare metal, giving you a low-level Python operating system that can.
