[Other resource] PinYin_InputMethod_C51 DL : 1: 用C51实现的拼音输入法,这是改写的网友 embuffalo、独步上载在www.21ic.com自由发布区的由张凯原作的51上的拼音输入法程序。原作使用了一个二维数组用以查表，我认为这样比较的浪费空间，而且每个字表的索引地址要手工输入，效率不高。所以我用结构体将其改写了一下。就是大家现在看到的这个。因为代码比较的大，共有6,000多汉字，这样就得要12,000 byte来存放GB内码，所以也是没办法的 :-( 编译结果约为3000h,因为大部分是索引表，代码优化几乎无效。在Keil C里仿真芯片选用的是华邦的W77E58，它有32k ROM, 256B on-chip RAM, 1K on-chip SRAM (用DPTR1指针寻址,相当于有1K的片上xdata)。条件有限，没有上片试验，仿真而已。打算将其移植到AVR上，但CodeAVRC与IAR EC++在结构体、指针的定义使用上似乎与C51不太一样，现在还未搞定。还希望在这方面有经验的网友能给予指导。-C51 with the Pinyin input method, which is rewritten netizens embuffalo. Unrivaled www.21ic.com available in the free publication of the original work by Kai-51 on the Pinyin input method procedures . Appreciate the use of a two-dimensional array for the look-up table, I think this is a waste of space. Each of the characters but the index table to manually input address, efficiency is not high. I use the structure to rewrite a bit. We see now is this. Because the code comparison, a total of 6, more than 000 Chinese characters, this must be 12, byte to store 000 GB code, is not the way to compile results :-( about 3000h. because most of the index table.
