摘要：

我先把這個完整的源程序發表出來，還沒有中文注釋，由於在編寫這個程序時是在DOS下完成的，不方便中文注釋。以後我會開設一個學習天地的欄目，我將在裏麵分段講解它，於這個軟件配套的硬件電路板采用的是8031單片機，擴充了2764（8K）的EPROM存儲程序，以X25043P 這個芯片做為保存配方的EEPROM 可以掉電保存，同時這個芯片還具有看門狗電路，在程序中也利用了這一功能，的可以保存20個配方，具有14路按鈕輸入，7路按鍵輸入，6路控製輸出，具有手動和自動配料功能，具有微打輸出，可以直接聯接一款RP-40的微打，可能其它微打稍加改進程序就能用。硬件上還采用了8155和8255兩個輸入輸出接口芯片，采用了8259芯片做為LED顯示和鍵盤輸入的控製芯片，輸入輸出有光電隔離，有電路板用的機械觸點的OMRON公司的繼電器，可以直接外部驅動中間繼電器工作。有興趣的網友可以先下載這個程序。在相關的仿真器上試試，我會在以後陸續對其中的重點程序加以說明。康為水泥閥
