Freescale 8-bit Mcu Teaching Experiment Platform Development And Research

Freescale MCU is all in readiness , apply to different occasions, and has bigger applicability. Now, the new generation MC68HC908 MCU which is at present, has the very high function price ratio. But Freescale company enter China comparatively late, and so many exploitation engineers don't know its superiority very much. Teaching in university, engineer's exploitation all require a set of exploitation system that has the very high function price ratio, which will be used in function testing , system evaluation and so on. The beginning of the paper thoroughly studied the monitor programme in the ROM of MC68HC908 series MCU , and has particularly analysis the means to Flash programming using the monitor programme in the ROM, has establish the solid basis for the exploitation of the teaching expeiment platform. Afterwards, the paper made a minute description about the exploitation of MC68HC908QY4 teaching experiment board from the overall design, the hardware design, software design and the user monitor programme. And successfully transplants the MC68HC908QY4 user monitor programme to MC68HC908QY4A, through which exploitation engineers can made new experiment on MC68HC908QY4 teaching experiment board used MC68HC908QY4A. Last, the paper have submitted modification scheme specifically for that Suzhou University SD-1 type MC68HC908GP32MCU testing exploitation environment can not debug in line. And through studying the USA MCUSLK system, the paper have designed a set of system combining with the teaching of our country condition , which is systematic on the function as USA MCUSLK system. Developer realizes functions conveniently such as online programming, breaking point debugging, dynamic programme memory and so on, and applies to relevant fields.
