Embodiment
Core of the present invention is to provide a kind of AccessPort cable based on USB connector, in the process to electronic equipment exploitation debugging, can save space, can save the resources such as IC material again, make AccessPort simple more economically.
In order to enable above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth detail in the following description so that fully understand the present invention.But the present invention can be different from alternate manner described here to implement with multiple, those skilled in the art can when without prejudice to doing similar popularization when intension of the present invention.Therefore the present invention is not by the restriction of following public embodiment.
Please refer to Fig. 1, the AccessPort cable structure schematic diagram based on USB connector that Fig. 1 provides for a kind of embodiment of the present invention.
In a kind of embodiment of the present invention, a kind of AccessPort cable 1 based on USB connector, comprise: cable main body 11, the two ends of cable main body 11 are respectively equipped with the first USB connector 12 and the second USB connector 13, first USB connector 12 is for connecting the UART interface of debugged apparatus, 2nd USB connects 13 devices for connecting the USB interface of debugging computer, the TTL serial port transform USB module 14 for Transistor-Transistor Logic level being converted into USB level is also provided with in cable main body 11, TTL serial port transform USB module 14 connects the first USB connector 12 and the second USB connector 13 respectively.
In the present embodiment, TTL serial port transform USB module is typically designed to IC chip, because the Transistor-Transistor Logic level of debugged apparatus uses UART interface, therefore, so-called TTL serial port transform USB module and TTLUARTtoUSB chip, TTLUARTtoUSB chip is arranged in cable main body, directly the Transistor-Transistor Logic level of the UART interface of debugged apparatus can be directly converted to USB level.The Transistor-Transistor Logic level of the UART interface of debugged apparatus is directly picked out by the first USB connector, TTL serial port transform USB module is used directly Transistor-Transistor Logic level to be converted into USB level, then this USB level is connected with debugging computer via the second USB connector, by debugging computer, debugging development is carried out to debugged apparatus, USB connector is much smaller relative to serial port connector volume Transistor-Transistor Logic level being converted into RS232 level, effective saving connector PCB space, effectively save the per-interface space at debugged apparatus place simultaneously, and without the need to the level conversion of complexity, the waste of IC resource can not be caused.
In order to save PCB space further, in one embodiment of the present invention, the first USB connector is MicroUSB connector.MicroUSB connector is a portable version of USB2.0 standard, and the more common USB interface of this interface volume is less, and can repeatedly plug, and has longer serviceable life.
