In order to provide more convenient options for users and developers, the design of Human Machine Interface (HMI) based on ARM and embedded Linux is put forward. It makes full use of multiple peripherals of ARM and flexibility of Linux OS. Firstly, hardware design of the HMI system is presented. Then methods of embedded Linux transplanting and the device drivers programming are discussed. Finally, running results and applications of the designed HMI are considered. The design combines the features of traditional HMI and Micro Control Unit (MCU) HMI, including low cost, rich interfaces and easy programming.

Based on the excellent performance of Pt100, a portable low-cost precision temperature sensor has been designed, whose core chips are REF03, AD8603, AD7788 and precision resistors. Constant current source (CCS) for 4-wire Pt100 is constituted by REF03, AD8603 and precision resistors. AD7788 measures the differential signal on Pt100 and suppresses the common mode interference signal. Analysis software running on the micro control unit (MCU) filters the digital code from AD7788, and then calculates the current temperature value according to the resistance-temperature mathematical model of Pt100. Analysis and experimental results show that the temperature measurement accuracy of the sensor can reach ±1°C within the range of 0°C-650°C.

The intelligentizing of sensor has been an important trend for sensor technology in recent years. In this paper, the new structure of the intelligent color scale sensor is presented; especially the software system design of intelligent color scale sensor based on the photoelectric measurement is given in detail. By using the control system based on Micro Control Unit (MCU), which takes full advantage of the resources on MCU, a new digital intelligent color scale sensor is successfully developed at a lower cost. Also, it has an ideal performance on the key index such as sensitivity, detection accuracy, response speed, reliability, operability and degrees of protection.

Stage Lighting

At present, most of the stage lighting console designs are based on MCU(Micro Control Unit), but its technique advances, information storage and real-time performances are deficient. This paper proposed that using the technique of ARM-Linux can realize the function of lighting console. This technique adopted S3C2440 processor as the main control chip of the hardware. The transmission of dimming data followed the DMX512 agreements. The low-level driver programs were developed under linux2.6.12, it provided interfaces for upper layer application. Testing results show that this system has perfect dimming performance and scalability, which is easy to upgrade. Our design has important theoretical significance and practical value for stage lighting control.
