Afterwards, gas alarm button (17,18,19,20) is pressed again eliminates alarm；When a certain element failure in device, failure
The flash for prompting user of indicator lamp 22 is faulty to be occurred.
As shown in figure 3, MCU minimum systems include power supply (VCC3.3), single-chip microcomputer (STM32Fxxx), clock circuit (at a high speed
Outer clock circuit (HSL：C20, C21, Y2, R21), (low speed external clock circuit LSE：C23, C24, Y3)), reset circuit
(R22, C22, R23, S3) four parts are constituted, and power sources in parallel C26, C27, C28 have reached good filtering.The minimum system of design
In system, 1M electric capacity R17 is added in high speed outer clock circuit (HSL), it functions as impedance matching, makes the drive of crystal
Dynamic circuit or crystal are in better condition of work in itself.Reset circuit is resetted by button and electrification reset two parts are constituted,
(1) electrification reset：STM32 series monolithic and for low level reset, generally on reset pin NRST connect an electric capacity (C22)
To GND, reconnect a resistance (R22) and arrive VCC, be consequently formed a RC charging and discharging circuit and ensure single-chip microcomputer NRST when upper electric
The low level for having enough time on pin is resetted, and is then revert to high level and is entered normal operating conditions.(2) button resets：
Button reset be exactly in reset capacitance (C22) one in parallel switch, when switch is pressed electric capacity (C22) be discharged, NRST
Low level is pulled to, and due to electric capacity (C22) charging, the low level of a period of time can be kept to make monolithic processor resetting.
As shown in figure 4, turning TTL module circuit diagrams for RS232, it is mainly used in computer and the device is communicated.
As shown in figure 5, being transistor amplifier and buzzer circuit, triode is NPN type, because 9013 triode work(
Rate does not have 8550 greatly, so being driven using 8550 triodes, R1 is the current-limiting resistance of base stage.
