PC MCU PC-based test kit MCU power management system

摘要

The present invention relates to a power supply method for protecting a computer loss due to an overload current when a USB power supply is applied to a computer-based MCU test kit and smooth operation of an experimental kit. In an MCU-based experiment using a computer, There are various overcurrent hazards such as error or over-current on the test kit. When the overload current flows in various kinds of experiment equipment using the USB power of the computer, the high-end computer has the protection circuit such as the current cut-Is often shut down or the computer's own USB port is too high to crash the expensive computer in many cases. In order to prevent such a problem, an overcurrent detecting unit is provided at a power input terminal of an experimental apparatus. When an overcurrent is supplied, an MCU or a hardware control unit on the test kit detects the overcurrent, Buzzer or other alarm device to prevent the computer from malfunctioning. In addition to informing the experimenter about the status of the overcurrent, it also informs the voltage and current value on the LCD in real time, (Voltage, current) to enable the experimenter to recognize the value and the current consumption.;
