The stm32 single-chip microcomputer minimum system is composed of a single-chip microcomputer chip, a clock circuit and a reset circuit. The chip is the minimum system core component, the clock circuit is used for providing clock beat signals, and the reset circuit is used for providing reset signals.
A clock circuit: the system clock circuit serves the stm32 singlechip and provides accurate clock beats for the stm32 singlechip during operation, and the 12M crystal oscillator is selected in consideration of the requirement of accurate operation in design. The specific clock circuit is shown in fig. 6.
A reset circuit: the reset modes of the stm32 single chip microcomputer are power-on reset, manual reset and program automatic reset respectively.
Power-on reset: that is, at the moment of powering on the single chip microcomputer, the level of the RESET pin is pulled down by using the instantaneous low level appearing in the capacitor charging process connected with the RESET pin of the single chip microcomputer, so that the RESET operation of the single chip microcomputer is caused, the low level duration time can be changed by adjusting the size of the resistor and the capacitor in the circuit, and the specific calculation formula is as follows: t is 1.1RC (fixed calculation formula) 1.1K 0.1uF is 1.1 ms.

The design uses stm32 with the smallest plate being reset low. Namely, when the key is pressed, the RSTSET end is at a low level, the system reset is realized, and when the key is released, the RSTSET end is at a high level, and the reset is finished.
The reset circuit is shown in fig. 7.
The infrared receiving head has three pins outwards, Out is directly connected with the IO port of the single chip microcomputer, GND is connected with a system ground wire (0V), and Vcc is connected with the anode (+5V) of a system power supply.
The working principle is as follows: the infrared ray is emitted by an infrared emitting device (an infrared ray bulb), the infrared ray signal is received by an infrared receiver of a receiving end after the emitted infrared ray is transmitted in the air for a period of time, the visibility in the air is poorer as the humidity is higher, therefore, the amplitude of infrared ray attenuation is larger, the intensity of the infrared ray received by the receiving end is inversely proportional to the humidity of the air, the received infrared ray is converted into a voltage signal by the receiver, the stronger the received infrared ray is, the larger the output voltage is, the weaker the infrared ray is, the lower the output voltage is, the humidity can be reversely deduced according to the magnitude of the output voltage, and finally all data are sent to a single chip microcomputer processor to be calculated to obtain a corresponding humidity value and are displayed through a liquid crystal display.
Because the system only has certain unreliability through infrared detection, the system also detects the image of the environment through the camera by an auxiliary detection means, the visibility is judged through the visibility of the image, and the detected data is processed through the microcomputer, so that the detected numerical value is more accurate.
