This paper specifically describes the design of hardware and software of a digital pulse oximeter based on ARM core embedded system and light-frequency converter. In this study, a light-frequency converter instead of a photodiode was adopted to receive the light transmitting, which greatly simplified the design of hardware. Besides, traditional methods of(More)
This paper proposes an embedded terminal platform for wireless telemonitoring, which supplies extensible digital interface to biomedical sensors, with a thorough power management unit, a user-friendly interface design and ingenious driver programs to support hardware operations. The digital interface connects the S3C2440 processor with various biomedical(More)
