The debugging major part of unit and module is all to send control instruction with the serial ports of computer to carry out at present, if needed
SPI, I2C or CAN control protocol to be produced the most also needs to be equipped with corresponding modular converter.In outfield or the situation of debugging of going on business
Lower desktop computer is inconvenient to carry, and currently the majority notebook does not the most configure serial ports.This utility model patent is good
Solve this problem.
Utility model content
Utility model purpose: the purpose of this utility model is to solve deficiency of the prior art, it is provided that a kind of needs
User, by one piece of touch screen input serial ports control instruction, just the same with computer can produce serial ports control instruction, to unit and mould
The debugging efforts of block brings great convenience.This touch screen serial ports controller volume is little, lightweight, be convenient for carrying can do several
The touch screen controller of the debugging spare part of all units and module.
Technical scheme: a kind of touch screen controller described in the utility model, including touch screen, dsp controller, SPI adjusts
Try mouth, I2C debugging interface, CAN debugging interface and AccessPort interface, described touch screen by data/address bus with described
Dsp controller connects, and the outfan of described dsp controller is connected to SPI debugging interface, I2C debugging interface, CAN debugging
Interface and AccessPort interface, described SPI debugging interface, I2C debugging interface, CAN debugging interface and AccessPort interface
Outfan be connected with assembly to be debugged respectively, described dsp controller is also associated with reset circuit and crystal oscillating circuit.
Further, described touch screen is connected with RS232 drive circuit by data/address bus, described RS232 drive circuit
It is connected with described dsp controller by com interface.
