Description
Technical field
The utility model relates to a kind of single-chip microcomputer hardware art, specifically, relates to a kind of controller general write device hardware platform.
Background technology
Commercially support that the general writer of Freescale S12/S12X 16 MCU is little at present, Freescale S12/S12X 16 MCU are a single-chip microcomputers of Freescale Semiconductor, MCU is the abbreviation of Micro Control Unit, and Chinese is micro-control unit.Major part general writer cost price is high, and function is complicated, erasing, write operation inconvenience, and unstable in operation; The chip kind that this serial write device is supported is also less, and extensibility is not high, cannot support 16 MCU that Freescale series is new.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of controller general write device hardware platform, can realize carrying out the erasing of data, write and debugging operations to Freescale series 16 MCU.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of controller general write device hardware platform, comprising: control processor, BDM debugger interface unit, usb interface unit; Described control processor carries out BDM drived control after being connected with described BDM debugger interface unit; Usb data communication is carried out after described control processor is connected with described usb interface unit; Described control processor and the energising of described BDM debugger interface unit are energized by described usb interface unit.
Preferably, described control processor is MC68HC908JB8 chip, and MC68HC908JB8 chip is provided with pin PTA1, PTA4, PTA5, PTA6, PTA7, VDD, PTE3, PTE4, VSS.Described BDM debugger interface unit is the driving interface circuit be made up of 74HC125 chip, and 74HC125 chip is provided with pin RST OUT, BDM DRV, RST IN, BDM IN, BDM OUT; Described usb interface unit is provided with pin VCC, D-, D+, GND.
Preferably, the PTA1 of described control processor, PTA4, PTA5, PTA6, PTA7 carry out BDM drived control with RST OUT, the BDM DRV of described BDM debugger interface unit, RST IN, BDM IN, BDM OUT after being connected respectively.
Preferably, VDD, PTE3, PTE4, VSS of described control processor carry out usb data communication after being connected with VCC, D-, D+, GND of described usb interface unit respectively.
The beneficial effects of the utility model are: can realize carrying out the erasing of data, write and debugging operations to Freescale series 16 MCU; Complexity is low, cost is low, reliable and stable, simple to operate, can versatility good.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of controller general write device of the utility model hardware platform;
In accompanying drawing, the mark of each parts is as follows: 1, control processor; 2, BDM debugger interface unit; 3, usb interface unit.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of controller general write device hardware platform, comprising: control processor 1, BDM debugger interface unit 2, usb interface unit 3; Described control processor 1 is MC68HC908JB8 chip; Described BDM debugger interface unit 2 is the driving interface circuit be made up of 74HC125 chip; Described usb interface unit 3 is form usb circuit by PTE3, PTE4, VDD, VSS tetra-pins of control processor; PTA1, PTA4, PTA5, PTA6, PTA7 of described control processor 1 carry out BDM drived control with RST OUT, the BDM DRV of described BDM debugger interface unit 2, RST IN, BDM IN, BDM OUT after being connected respectively, can realize the operation of wiping MCU, write or debugging; Usb data communication is carried out after VDD, PTE3, PTE4, VSS of described control processor 1 are connected with VCC, D-, D+, GND of described usb interface unit 3 respectively; Described control processor 1 and described BDM debugger interface unit 2 are energized by described usb interface unit 3.
Principle of work of the present utility model is: described control processor 1 is received by PC(personal computer Personal Computer by described usb interface unit 3) side send data or instruction.Then by operation that described BDM debugger interface unit 2 couples of MCU wipe, write or debug.
A kind of controller general write device hardware platform described in the utility model can realize carrying out the erasing of data, write and debugging operations to Freescale series 16 MCU, and complexity is low, cost is low, reliable and stable, simple to operate.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
