可以熟悉51单片机中断机制 大大方便学习51单片机

美国TI公司的protel 元器件库，在应用中需要更新，本人收集了最新的版本共30M，为提高上传速度分六次上传。文件名依次为TI_1到TI_6。希望大家设计电路板时少走弯路。由于在上传时找不到分类，所以归结为书籍一类-TI" s U.S. Treasury protel components, need to be updated in the application, I collected a total of up-to-date version of 30M, to improve the upload speed upload six hours. File name followed by TI_1 to TI_6. Hope that the design of circuit board less detours. From when can not find in the classification, it comes down to a class of books
