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

这个通用的Bootloader可以支持大部分具有自编程功能、带有Boot区和UART串口的AVR单片机（主要是Mega系列）。如果是多串口的单片机，可以任意选择使用其中的一个串口。程序支持RS232/RS485/RS422方式，如果程序稍加修改，也应当可以很容易的支持USI、SPI、I2C等接口。
