Design And Implementation Of Universal M68hc08 Mcu Programmer

With the rapid development of SCM technology, various new models, high- performance single chip are emerging. Freescale M68HC08 family of microcontrollers is one of the company (formerly Motorola company) launched in recent years with a new generation of cost-effective 8-bit microcontroller, it has a fast, powerful, low price and power consumption characteristics, there are a hundred a variety of models into the market, while, Freescale company continues to introduce new types of sub-series of products to meet the needs of the broader market. In embedded development, embedded development is inseparable from the programmer and other tools. Programmer can be generated after compiling the target program writes to the target MCU chip, usually in order to achieve the target MCU Flash memory write, read and erase functions. While Freescale offers chips supporting the program, but due to their cost which can not be accepted by the majority of domestic users, to support the domestic market to support Freescale's Microcontroller Programmer rare, and for the Freescale has introduced the company's new models microcontroller, some programmer will do nothing to help. Freescale reference document provides the most typical circuit serial programming. The circuit design and cumbersome to use, on the one hand and the serial does not support hot-swappable power supply, the other for the same series of complex but also the different MCU jumper. To this end we choose the design with usb interface M68HC08JB16 a programmer, the programmer interfaces with the PC through the USB is connected, power from the USB interface to work directly, eliminating the power supply module, reducing cost. Emerging target MCU programming, as long as the data to find the MCU, to enter according to the type of MCU to monitor conditions and design the corresponding adapter head can be programmed using the PC, software is more conducive to the use of Chinese user interface operation.The subject of hardware and software by programming the design of studies to finally realize the M68HC08 series MCU's programming, and in the process of solving the USB protocol communication, the master MCU program design, based on the actual needs of their own design USB under windows driver, PC side software interface modeled on the P & E's P & E 68HC08 Flash Programmer software to design, interactive and friendly, easy to operate and easy to learn, I hope one day we do the software simply by adding the dynamic link library and a few files will be able to complete and P & E 68HC08 Flash Programmer integration.
