用89C52制作太阳电池数显充放电控制器原程序.说明：70H内存单元存放采样值，78H-7AH存放显示的BCD码数据；自然就依次为个位、十位和百位，模数转换器是ADC0809-89C52 production of solar cells with a number of significant charge-discharge controller original procedures. Descr iption: 70H memory unit storing sampled values, 78H-7AH store display BCD code data　naturally followed by a bit, 10 and 100, ADC is the ADC0809
