随着电子技术的发展,计算机变得不再神秘。作为计算机家族的“小兄弟”,单片机在控制系统以及家用电器上的应用也越来越广泛。所以,越来越多的爱好者也开始涉足这一领域。首先遇到的问题是:如何给单片机置入地址或数据? 单片机的开发需要专用的设备,其价格较高。爱好者大多可从数据/地址置入器开始。简单的数据/地址置入器,多采用拨动开关或组合式琴键自锁开关,体积大,速度慢,手感也不好。笔者对此进行了改进。改进后的电路仅用三片集成电路,器件易寻、成
With the development of electronic technology, the computer becomes no longer mysterious. As a computer family “little brother”, SCM in the control system and household appliances are also more and more widely used. Therefore, more and more fans are beginning to get involved in this field. The first problem encountered is: how to put the microcontroller into the address or data? Single-chip development needs special equipment, the higher the price. Most enthusiasts can start with the data / address organizer. Simple data / address inserter, multi-use toggle switch or combination of keys self-locking switch, bulky, slow, feel is not good. I have made improvements to this. Improved circuit with only three integrated circuits, the device easy to find, into
