[Training Camp_Advanced Class]'Socket'-I am connected to the Internet

Overview

Practical implementation of Internet of Things projects... I want to play with many main controllers and choose STM32F103, because this is the chip I use most currently. I have it on hand. It is about 6 yuan for a cheap one on a certain treasure. It is also very affordable. The main frequency is 72M and the performance is also good. Very good, the key is that I want to run an RTOS IoT system. I wanted the system to work without power, so I added lithium battery power supply and corresponding power supply and power management. A small OLED screen was added. A DIP switch is used in the middle of the serial port to choose whether to use AT or microcontroller for communication. The 8266 also supports flashing firmware, and has also been windowed for large currents, and can be tinned later.
