As embedded systems with small size , good performance , low power consumption , high reliability , as well as a prominent feature of the industry-oriented applications , has been widely used in military defense, consumer electronics , home appliances, network communications, industrial control and other fields . Research and development for embedded technology teaching , research , design, experimental and simulation platform , effective measures to further promote the rapid development of embedded technology . In the industry 's performance ARM7TDMI core S3C44B0X processor and OS- II real - time operating system , designed for embedded systems experimental platform for teaching and research . The platform hardware with a minimum system of open and modular structure design , the system core board to S3C44B0X processors of SUMSANG , FLASH , SDRAM , power supply circuit , reset circuit and the main clock circuit , USB interface , Ethernet interface and JTAG debug interface modules ; motherboard from the digital display and keyboard control module and touch screen control display module. ADS1.2 compiler environment , could perform system programming , debugging , simulation , and download function . The core board , transplantation Bootloader loading and OS- II real-time operating system , enabling it to offline conditions , constitute a fully independent embedded systems . In order to verify the correctness of the design of the motherboard hardware circuit design and working principle of the two typical man-machine interface circuit : keyboard scanning and touch-screen control structure are analyzed in detail , and written in assembly language and C language keyboard scan control and touch screen display program ; circuit and debugging , analyze and solve some practical problems encountered and identified many factors affect the stability of the circuit . The system uses an open and modular design, hardware configuration is complete , the software provides C language and assembly language programming examples , system hardware and software resources , provides a good university science and engineering undergraduates , graduate students , and researchers experimental / research and development platform .
