每次开机都将次数加1 并存储到EEPROM。这样就能直观的看到机器的使用次数。用P1口 LED做为显示，次数大于256是将溢出，按复位模拟开机 或者直接通过开关开机。-Each boot will add a number of times and stored in EEPROM. This will be able to see the intuitive usage of the machine. As with the P1 port LED display, frequency is greater than 256 is the overflow, according to reset the boot, or directly through the analog switch boot.
