計算機并口轉(zhuǎn)3路串行DA的DLL源碼及電路,芯片MAX541/MAX5541,可以免費申請,8路I/O輸出,5路輸入,并口的簡單極限應(yīng)用.經(jīng)使用各項性能不錯,就是DA抗干擾較差,沒有較大的電磁干擾運行穩(wěn)定.電路初步設(shè)計,有很多問題,請自行修改,切勿商用!在此特感謝李高的技術(shù)支持

The PCI Local bus concept was developed to break the PC data I/O bottleneck and clearly opens the door to increasing system speed and expansion capabilities. The PCI Local bus moves high speed peripherals from the I/O bus and places them closer to the system’s processor bus, providing faster data transfers between the processor and peripherals. The PCI Local bus also addresses the industry’s need for a bus standard which is not directly dependent on the speed, size and type of system processor. It represents the first microprocessor independent bus offering performance more than adequate for the most demanding applications such as full-motion video.
