地磁炉控制程序 （带三位8字数码管显示，MCU用HOLTEK 46R47，18PIN，8M晶振，取消所有I/O口的内部上拉电阻）-geomagnetic furnace control procedures (with three eight characters Digital Display, MCU with HOLTEK 46R47. 18PIN, 8M Oscillator, the abolition of all I/O I draw the internal resistance)

本程序实现标准浮点数除法。 入口参数：被除数在ARGBH1:ARGBL1:EXP1中，除数在ARGBH2:ARGBL2:EXP2中。 出口参数：结果在ARGBH1:ARGBL1:EXP1中。-This procedure to achieve the standard floating-point division. Entrance parameters: dividend in ARGBH1: ARGBL1: EXP1, the divisor in ARGBH2: ARGBL2: EXP2 in. Export parameters: the results of ARGBH1: ARGBL1: EXP1 in.

用汇编语言实现的倒计时器，利用1C中断每秒中断约18次的特性，在根据中断次数计算时间，每过一秒，时间以十进制显示在屏幕上，时间减到零时程序退出。-Using assembly language implementation of the countdown device, using 1C interrupted about 18 times per second interruption characteristics, in accordance with interruptions computation time, with every passing second, the time displayed on the screen in decimal, the time reduced to zero to quit.
