Ç - 如何使用PROGMEM存储和读取字符数组 [英] C - how to use PROGMEM to store and read char array

问题描述

我有三个字符数组，而我不希望Arduino的存储那些 SRAM ，所以我想用PROGMEM存储和闪存读取代替。

 的char * firstArr [] = {选项1，选项2，选项3，4选项};
字符* secondArr [] = {测试1，测试2};
 

解决方案

有一个关于如何做precisely本的 Arduino上网站。 （参见字符串数组下）。

I have three char arrays, and I don't want Arduino store those in SRAM, so I want to use PROGMEM to store and read in flash, instead.

char *firstArr[]={"option 1","option 2","option 3","option 4"};
char *secondArr[]={"test 1","test 2"};

解决方案

There's an example on how to do precisely this on the Arduino website. (See under "Arrays of strings".)
