本次设计的温度计采用HT46RB50 微控制器IC，HT46RB50 的AD 口外接一热敏电阻，通过 AD 读回的电压计算出热敏电阻阻值的变化，从而实现侦测外界温度的功能。HT46RB50 通 过USB 将侦测到的温度值传入PC 机的温度显示接口中显示。 本次设计的USB 使用操作系统提供的USB HID 设备类驱动程序。 • 采用USB 控制传输向HT46RB50 发送资料 • 采用USB 中断传输接收HT46RB50 传回的资料-The design of the thermometer used HT46RB50 microcontroller IC, HT46RB50 of AD external mouth of a thermistor, through the AD read-back voltage to calculate the changes in thermistor resistance in order to achieve the function to detect the outside temperature. HT46RB50 through the USB will be detected by the temperature of the temperature of incoming PC-display interface to display. The USB to use the operating system designed to provide the USB HID device class driver.

基于arm的示波器设计，内含单片机控制外部驱动程序-Based on the arm of the embedded microcontroller control design, oscilloscope external driver
