| Abstract: | A scanning fluorometer Instrument based on embedded Linux system is designed. It detected fluorescence test strip by stepper motor, and used Samsung S3C2440 as processor. Its kernel is Linux2. 6. 32. This article focuses on how to write embedded Linux stepper motor driver, and optocoupler driver, and makes a brief introduction about how application software controls stepper motor. By test, stepper motor worked steadily, and it can totally meet the equipment requirements. |
