利用MSP430单片机实现5分钟倒计时。用Timer_A实现1s定时，4位共阳型数码管显示时间，显示格式为：“x-xx”，分别代表“分”、“十秒”和“秒”。每隔1s，倒计时器的时间减1，倒计时从4分59秒开始计时，至0分0秒结束，停止计时。(MSP430 microcontroller is used to realize 5 minute countdown. Timer_A is used to realize 1s timing and 4-bit common-sun digital tube display time. The display format is "x-x x", representing "minutes", "ten seconds" and "seconds" respectively. Every 1s, the countdown time is reduced by 1. The countdown time starts at 4:59 seconds and ends at 0:0 seconds.)

说明：  STM32 gps定位+姿态传感器系统，用于小车位置方向的导航定位。(STM32 GPS positioning + attitude sensor system is used for the navigation and positioning of the car position direction.)

单片机00-99计时器，采用静态数码管显示00-99计时(SCM 00-99 timer, digital display 00-99 static timing)

三星单片机资料比较少本程序实现S3F84U8看门狗-使能并喂狗(Samsung SCM relatively little information this program S3F84U8 Watchdog- enabled and feed the dog)

说明：  spi模拟i2s，实现音频播放，网上的参考，不易找到，供大家分享(spi simulation i2s, for audio playback, online reference, easy to find for people to share)
