“…The data can be transported from IC6 to the displayer via the output ports of P00–P07 in CPU connecting with the pins of D0–D7 in the monitor. Thus the automatic displaying can be realised, which can be supported by other similar practical demonstrations [16, 17].…”

A setup was constituted for measuring reverse recovery (RR) waveforms of current I rr and voltage V rr , RR time t rr , RR charges Q rr , as well as the ratio C of absolute value of RR peak voltage V rm to amplitude of reverse biased pulse voltage V r and so on, for power device under test (DUT). Forward pulse current I f and the V r were generated from a central processing unit (CPU). Amplitude of I f was magnified by a transistor, while the scale was regulated via a Darlington array controlling relays for altering different resistors connected to emitter of the transistor to apply on DUT. Pulse of V r was first shaped by a Schmitt trigger and then was magnified by a metal-oxide-semiconductor field-effect transistor (MOSFET), while the edge commutating rate dI f /dt was adjusted through the Darlington controlling relays for changing different inductors linked to drain of the MOSFET to bias on DUT. The waveforms can be observed with an oscilloscope and sampled for further digitally processing. Inputting test parameters via keyboard, calculating and displaying of test results can be controlled by a host CPU. The parameters and metering results can be monitored by a liquid crystal displayer (LCD).

STM32 is a microcontroller based on CortexTM-M3 core; it plays an important role in the embedded control field. This chapter introduces a low-power humidity and temperature collector with SHT10 humidity and temperature sensors. This chapter introduces and implements the communication time sequence of SHT10. A calibration text proves that the system can measure temperature and humidity correctly. It is demonstrated by experiments that this low-power collector can collect data for 30 days and satisfy the design index; besides, the principle of low power can be used in other embedded control field.Keywords Temperature and humidity collector · Low-power mode · STM32F103 IntroductionSTM32 is widely used in many control applications. It is a microcontroller based on CortexTM-M3 core, which sets new standards in capability and cost as well as low-powered operation and real-time control. The series mainly includes three subseries: "A" means high applications, "R" means real-time applications series, and "M" means cost-sensitive and microcontroller applications. STM32 belongs to the "M" series, which is designed for the coalescence of high capability and low power [1].Most of the humidity and temperature collectors on the market do not have the ability of recording and low power at the same time; in addition, they are expensive. This chapter designs a humidity and temperature collector based on STM-32F103RET6. Its system can work for about 30 days with the ability of recording and a stop mode has been adopted for the purpose of power saving. The sensor is SHT10 humidity and temperature sensor. The collection period takes 5 min, and 18,650 lithium battery works as the power supply. The data can be recorded in the secure digital (SD) card. The collector can support high-speed universal serial bus
