计算机并口转3路串行DA的DLL源码及电路,芯片MAX541/MAX5541,可以免费申请,8路I/O输出,5路输入,并口的简单极限应用.经使用各项性能不错,就是DA抗干扰较差,没有较大的电磁干扰运行稳定.电路初步设计,有很多问题,请自行修改,切勿商用!在此特感谢李高的技术支持

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.
