HT48 & HT46 MCU UART 的軟件實(shí)現(xiàn)方法具有低功耗、高性能的HOLTEK 的8 位單片機(jī)，十分適用于各種控制系統(tǒng)產(chǎn)品，如辦公自動化和一些消費(fèi)性產(chǎn)品中。有時(shí)在一些應(yīng)用系統(tǒng)中需要附加與其它單片機(jī)進(jìn)行異步串行通信，在這種情況下，使用軟件方法實(shí)現(xiàn)比選擇專用的IC 硬件方法要經(jīng)濟(jì)得多。本文就是介紹簡單的UART 軟件實(shí)現(xiàn)方法。該方法適用于帶一位停止位并且不帶奇偶校驗(yàn)位的通用8 位數(shù)據(jù)傳輸，其傳輸波特率可調(diào)整，調(diào)整范圍由使用的單片機(jī)的系統(tǒng)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.
