ADC C++ for 9S12XS128 FREESCALE

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)
