以Z-80、8080、6800等芯片作为CPU和各式单板机具有功能强、价格低和易于开发的特点,在测量、控制以及智能化仪器研制等许多方面获得了非常广泛的应用。但目前生产的各种单板机大都是最小组合系统,软、硬件配置简单,一般要经过二次开发才能真正投入实际应用。其中常见的硬件开发有:增加内存量、增配A/D、D/A转换电路,扩充串、并行通讯接口和各种控制电路等。表1给出了Z-80、8080、6800
With Z-80, 8080, 680 and other chips as a CPU and all kinds of single-board machine with strong features, low prices and easy-to-develop features, measurement, control and intelligent instrument development and many other aspects of access to a very wide range of applications. However, the current production of a variety of single-board machines are mostly the smallest combination of systems, software and hardware configuration is simple, generally after secondary development can really put into practical application. One of the common hardware development are: increase the amount of memory, with A / D, D / A conversion circuit, the expansion of string, parallel communication interface and a variety of control circuits. Table 1 gives the Z-80,8080,6800
