STM32 series single-chip microcomputer has been deeply hobby and sought after, every time I have a new, I always rushed a holiday, STM32-based practical applications are endless, a good information can help Xiaobai successfully introduced, helping everyone to advance the gods . I have organized 10 boutique STM32 series project information on the Circuit City. I will unlock the road to advance, and board the peak of life.
1, two-way DC-DC converter based on STM32
According to the two-way DC-DC converter designed for 15 years, the device uses PID control, the main function is constant current charge and constant voltage output. In the charging mode, the DC power supply charges the battery pack constant current charge, 1A to 2A stepping, step in value 0.1a, the control accuracy is less than 1%, the charging efficiency is greater than 90%; the discharge mode, the battery pack constant voltage output 30V drive Load, discharge efficiency is greater than 95%, and the control error is less than 0.1V ...

2. STM32-based smart desk lamp complete design
This design is implemented as follows:
1. When the human body is close to the lamp (1.5 m) and the environment is dark, the infrared sensation is turned on.
2. When the person working out under the tablelight (45 minutes) or too close (setting approach to myopia to form protection), remind people by flashing lights (can be manually stopped flashing or turning off).
3. When people leave (or brightness, the brightness) is smart.
4. The night light function, when there is a sound at night, open the lamp with a smaller brightness, lasting for 3 minutes.
5. Set a plurality of brightness gel gels and adjustable color temperature (touch switches), which can be set to a normal table lamp (turn off intelligence).

5, STM32 series design, ESP8266 networking time clock data
l based based on STM32F103C8T6 design
l Access the external network by operating the ESP8266, call the free API interface to get the current time
l Show out time and week visualization
The L-plate loader circuit, download mode is, first power off, press and hold the boot0 button, press the computer, and then download it.
l board design is compatible with two encapsulated ESP8266, soldering direct insertion ESP8266 needs to remove the needle-pin plastic barrier parts, directly to the board welding, then minus excess pin
L board design is inserted and is compatible with the straight insertion of ESP8266 and NRF24L01. Next to the plate silk printing resistor is used as the dot to be used as the ESP8266, welding is used for NRF.

6, STM32 wireless environment monitoring system DIY production and information
This design is based on the STM32 single chip into the core, divided into a collection and transmission section and the receiving control section. It can correctly collect air quality, smoke concentration, CO concentration, temperature and humidity data, successfully transmitted. In the receiving control section, all the data is displayed by the screen display, the air quality is determined and the alarm, the high and low temperature of the button adjustment setting is the temperature exceeds the standard alarm; the smoke concentration and the Co concentration are exceeded. Judging. The alarm part uses buzzers and LED lights.
