Abstract

The invention discloses a device which online debugs a microcontroller and the peripheral device thereof. The device includes a microcontroller used for receiving the protocol commands of the host computer and processing the data and a USB connector used for connecting with the host computer; the USB connector is provided with three contacts; the first contact is used for connecting the host computer with the microcontroller for communication and sending the protocol commands; the second contact is used for receiving the data sent from the microprocessor to the host computer; the third contact is used for supplying power for a voltage conversion module (2); at least a general I / O interface is connected with the microcontroller used for accessing the peripheral device and the data transmission between the microcontroller and the peripheral device; the voltage conversion module (2) converts the voltage provided by the USB connector and supplies the converted voltage for the microcontroller. The device in the invention realizes the debugging and configuring of the microcontroller in the system in the PC software interface, and the control of the peripheral device; the real-time and high-speed transmission of large quantity of data between the PC and the microcontroller is realized.

Description

technical field [0001] The invention relates to the field of computer serial communication, in particular to a device and method for online debugging of a microcontroller and its peripheral devices by using a universal serial port bus through a computer. Background technique [0002] Universal Serial Bus (Universal Serial Bus, USB bus) is a rapidly developing high-speed peripheral bus. The USB interface standard provides a single, easy-to-operate, standard connection type for all peripheral devices, and supports true hot plugging. Unplug (Hot plug) and plug and play (Plug&Play), allowing up to 127 interface devices to be serially connected to the same external USB interface of PC (Personal Computer) at the same time, realizing the communication between multiple peripheral devices and the host computer. The device and the host are connected through a USB cable, and the distance can reach 5 meters, making the device mobile. The latest USB2.0 protocol supports a maximum transmi...
