HT48 & HT46 MCU UART 的軟件實現方法具有低功耗、高性能的HOLTEK 的8 位單片機，十分適用于各種控制系統產品，如辦公自動化和一些消費性產品中。有時在一些應用系統中需要附加與其它單片機進行異步串行通信，在這種情況下，使用軟件方法實現比選擇專用的IC 硬件方法要經濟得多。本文就是介紹簡單的UART 軟件實現方法。該方法適用于帶一位停止位并且不帶奇偶校驗位的通用8 位數據傳輸，其傳輸波特率可調整，調整范圍由使用的單片機的系統頻率決定。

This application report discusses the design of non-invasive optical plethysmographyalso called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). Thepulsoximeter consists of a peripheral probe combined with the MCU displaying theoxygen saturation and pulse rate on a LCD glass. The same sensor is used for bothheart-rate detection and pulsoximetering in this application. The probe is placed on aperipheral point of the body such as a finger tip, ear lobe or the nose. The probeincludes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) andthe other in the infrared spectrum (940nm). The percentage of oxygen in the body isworked by measuring the intensity from each frequency of light after it transmitsthrough the body and then calculating the ratio between these two intensities.
