SCM system has crystal oscillator, full name to be called crystal oscillator, it combines the internal circuit of microcontroller to generate needed for microcontroller
Clock frequency, microcontroller crystal oscillator provide clock frequency it is higher, microcontroller operation speed it is faster, microcontroller connect all refer to
The execution of order is all built upon in the clock frequency of microcontroller crystal oscillator offer.Reset circuit has button to reset and electrification reset two
It is grouped as, [1] button resets：Button reset is exactly a switch in parallel, the capacitance when switch is pressed in reset capacitance (C22)
(C22) it is discharged, RST is also pulled to low level, since capacitance (C22) charges, can keep certain low level to make microcontroller
It resets.[2] electrification reset：STM32 microcontrollers reset for low level, and a capacitance (C22) is usually connect on reset pin RST and is arrived
GND arrives VCC in one resistance (R22) of connection, a RC charging and discharging circuit is consequently formed, ensures microcontroller RST feet when powering on
On there are enough low levels to be resetted, then revert to high level and normally worked.
In conjunction with attached drawing 5, serial ports can only download code, can not real-time tracking debugging, thus will utilize debugging acid, such as
ULINK, JLINK, STLINK etc. can real-time tracking program, to find the mistake in your program, STM32 microcontrollers are supported
JTAG and SWD, so adjustment method there are two types of us, uses JTAG to debug herein.
In conjunction with attached drawing 6, which is wireless module circuit diagram, and RST feet are the resetting pin of wireless module in figure, and low level has
Effect, high level operation, it should be noted that RST pins are generally operated when initialization, are forbidden after initialization
Using this pin, this wireless module has 6 common GPIO, our design that need not use, so need not connect, ANT
Pin is suitable for connection external antenna, generally uses spring antenna, scalable, and small, installation is simple.
In conjunction with attached drawing 7, used GPS module is the NEO_5Q master chips of u-blox companies of Switzerland production, this chip is

Block size is 3.57 × 1.52cm, and the pin of serial ports TXD, RXD and microcontroller is directly connected to.
In conjunction with attached drawing 9, DHT11 is numeric type humidity sensor, can directly be digitally transmitted acquired work as front ring
Border humiture, DHT11 are communicated using monobus, therefore need to only be connect the communication of a port I/O of microcontroller and DHT11
Mouth connection can realize the acquisition and transmission of data, fairly simple for other circuits.
In conjunction with attached drawing 10, HDP401 type pressure sensors use AD620 chips, the diaphragm of pressure sensor to be under pressure
When, resistance changes, and resistance is portion in the chip, constitutes a Wheatstone bridge, after resistance changes, electric bridge
The differential signal of 1mv grades of output, at this moment, we are amplified to volt grade by amplifying circuit, the millivolt signal of this difference, so that it may
Directly to be acquired by the AD of A/D chip or microcontroller, certainly it is also noted that be exactly sensor power supply mode, one
As there are two types of, one is voltage-types, exactly input constant voltage, another kind is current mode, it is desirable to provide one is constant
Electric current.The sensor that I uses is exactly 1.5mA current modes, and 1.5mA is maximum current, and using for current mode is slightly troublesome
A bit, it needs to design a constant-current source, but its advantage is that precision is relatively high, is affected by temperature smaller, answered for high-precision
With occasion, current mode is more advantageous.
