          如何將將字庫(kù)或圖片以數(shù)組的形式儲(chǔ)存在.c 文件中

          作者: 時(shí)間:2016-11-27 來(lái)源:網(wǎng)絡(luò) 收藏
          如果你所用的片上flash為20kB,而需要的漢字庫(kù)和啊撒可碼總共就有4-5kB,又不想用外部flash來(lái)儲(chǔ)存,當(dāng)然你是高手的話,下面的你就不用看了,寫(xiě)給新手的。

          我們新建一個(gè)xx.c文件,利用工具將我們所需要的漢字,字符,標(biāo)點(diǎn),生成16進(jìn)制的數(shù)組碼表,如下,

          .

          .}

          此只是舉例而已,切記,此處生成的數(shù)組定義時(shí)要使用const來(lái)定義,不用static和extern,否則編譯時(shí)仍會(huì)報(bào)內(nèi)存不足情況,const就是修飾為常量,編譯器通常不為普通const常量分配存儲(chǔ)空間,而是將它們保存在符號(hào)表中,這使得它成為一個(gè)編譯期間的常量,沒(méi)有了存儲(chǔ)與讀內(nèi)存的操作,使得它的效率也很高,這就是const的神奇之處。

          Xx.c文件中就是這些內(nèi)容,

          Xx.H的內(nèi)容就是聲明和定義了,

          #ifndef__xx_H__

          #define__xx_H__

          #definehzNum109

          externconstunsignedcharchardot_8x16[];

          externconstunsignedcharhzIndex[];

          externconstunsignedcharhzdot[];

          #endif

          此文件中需要供外部使用,聲明前加上extern,在使用的開(kāi)頭,#include”xx.h”就成功了!
