Abstract

The invention discloses a portable downloader, comprising a pen-shaped shell and a circuit board arranged in the pen-shaped shell, wherein a MUSB interface is arranged at one end of the circuit board; a ground wire and two data wires are connected on the circuit board; the other end of each data wire is connected with a probe; a yielding hole is arranged at one end of the pen-shaped shell corresponding to the MUSB interface; two locating holes are arranged at the other end of the pen-shaped shell; two probes penetrate through the locating holes; and the MUSB interface is connected with a computer USB (Universal Serial Bus) interface through a USB-MUSB computer extension wire. The portable downloader does not need external power due to the use of the UBS power supply and supports hot plug; the C2 interface is two probes, so that the data is conveniently transmitted to the C2 slave appliance; and the downloader is convenient to carry due to the pen-shaped encapsulation.

Description

technical field [0001] The invention relates to a portable downloader, in particular to a single-chip program downloader with a USB communication interface. Background technique [0002] The current digital communication interface can realize real-time detection and information reporting, online control and single-chip program download. The program debugging interface of Silicon labs C8051FXXX series MCU is generally C2 interface, including a C2CK clock signal and a C2D bidirectional data signal. [0003] Generally, the host computer itself does not have these digital interfaces, and only serial ports, parallel ports, and USB (universal serial bus) interfaces are commonly used; most notebook computers only have USB interfaces, and no serial ports. The USB interface is the most commonly used interface at present, and its hot-swappable feature makes it have a very prominent advantage in portability. Moreover, the transfer rate of the USB2.0 interface has reached a theoretic...
