Through "doing, doing middle schools", the way DIY is in the world of STM32 single-chip world from shallow depth. The following is sorted out 8 STM32 production instances on the Circuit City, complete design information, starting from simple work, step by step, grasping the STM32 microcontroller.
1. Remote Intelligent Car Circuit Solution (PCB + Source Code) based on STM32F401
Overall function: Remote control forward After returning left and turn right to stop command, speed up, car response; two button defaults to control the steering gear forward;
Remote control: Collect the rocker button battery voltage, display related data on the screen; wireless communication;
Car function: battery voltage, buzzer continuous alarm; ultrasonic detection is close to obstacle, buzzer continuous alarm;
Bluetooth, OLED, USB function is reserved, providing the possibility of more features to buyers;

2, based on STM32 Internet of Things smart home system (source code + schematic + BOM list)
The temperature, humidity, light intensity, soil humidity of the outside is detected by using a single-chip sensor information acquisition technology. If the temperature is too high, it is turned on by the relay control fan. If the moisture is too low, the control humidifier is opened by the relay, and it is turned off; if the soil humidity is too low, the control relay opens the water pump, and it is closed; if the light is insufficient, open LED fill the light. Through the ESP8266 WiFi module, the mobile app can remotely view the data. The cloud platform is a lattice cloud.

3, [Competition Project] Based on STM32F4 High Speed Spectrum Analyzer Full Version (Original)
The system is the core based on STM32F407, mainly using FIFO to make a cache. The high-speed signal is sampled by AD, then the sampled data is first cached first, and then the STM32F407 is added to the Blackman pre-processing, then do 1024 points FFT for spectrum analysis, and finally display the data on the LCD 12864 for Human-machine interaction! The system can realize the spectrum display of any-like waveform, and automatically look for the amplitude, frequency, and phase of each harmonic component and 8-bit valid data display.

4, based on STM8S003F3 home commercial security intelligent silent lock with electric locking function (including schematic, PCB and STM8 source program)
The system external DC12V power supply is powered by the DC-DC buck chip MP2359 to 5V to each part of the system. The main controller of the system is STM8S003F3, and the signal on the signal and the signal on the door magnetic (reed) by the main controller, and then control the operation of the stepping motor to switch the door to achieve the work of the entire system. . The system uses a triode to power out the detection circuit to determine whether the system is powered off, as long as the system is powered off, it will automatically unlock.
