Product Overview foolproof R680 G7 is a 4U rack server, it uses the Intel Xeon 7500 series compatible Intel Xeon 6500 series processors (Nehalem-EX) with Intel Xeon E7 series processors (Westmere-EX) and Intel Boxboro-EX IOH+ ICH10R chipset, with powerful data processing capability and good scalability, is a technology leader, with high reliability, ease of use, manageability and high scalability, and highly cost-effective high-end server products.)

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.)
