一、概述使用单板机调试程序时,常常由于RAM易受干扰或断电引起信息丢失;使用录音机反复转储调试程序则是既麻烦又容易出错;把程序固化在EPROM中调试也不方便,常常为修改1个字节的内容而不得不用紫外线擦去整片EPROM的内容再全部重写。为此,我们给TP801单板机扩展了两片廉价的E~2PROM2816。这样在断电时信息就不会丢失,而程序存储器的使用与RAM的使用一样方便。这方法也可应用于 First, an overview of the use of single-board debugger, often due to RAM susceptible to interference or power outage caused by the loss of information; repeated use of tape recorders debugger is cumbersome and error-prone; the program is not cured in the EPROM debugging is not convenient, Often to modify the contents of a byte and had to use UV to erase the entire EPROM content and then rewrite. To this end, we have extended the TP801 single board machine two cheap E ~ 2PROM2816. This information will not be lost in the power outage, and the use of program memory and RAM as easy to use. This method can also be applied to
