恐怕这是一个非常新手的问题，但是我已经尽力理解了这一点，但是由于我对C编程的经验很少，所以毫无进展。
我目前在一两年前从Instructables那里接一个旧项目：https://www.instructables.com/id/Jar-of-Fireflies/
这包括一个为Firefly模式编写的固件的C文件，但是该文件在12年前就已经写好了。
但是...我没有按照指令进行N级学习。相反，我使用的是DIP AtTiny85，我之前已经使用Arduino作为ISP对其进行了编程。因此，希望能够使用Visual Micro插件在Arduino IDE或Atmel Studio中编译代码。
每次在Arduino IDE中进行编译时，都会收到以下错误： 'prog_uint8_t'没有命名类型，这会导致很多错误。
据我了解，此减速已在2010ish左右作为AVR GCC的一部分进行了删除/更改...无论如何，我可以正确地编译此代码以运行代码吗？也许使用宏或包含一个库。我已经尝试了一些库，例如#include，但相信应该将其作为自动包含的一部分。我确定如果我带了合适的程序员，我的问题可能会消失，但是我确定对此有一个简单的解决方法。
在可指示的链接中以.tgz形式提供的代码，其中包括标题，c可执行文件，十六进制等，
用于快速阅读主要的c可执行文件清除。...

一旦为无符号8/16/32位int减速度定义了一种方法，我希望程序能够编译。
如果有人可以帮助我更好地了解这一点，那就太好了。因为当某个人花了很长时间使萤火虫alogrithims变得不错时，我不想编写自己的代码！但是，请我愿意学习，这样指向此类内容的任何链接也都很好。
答案 0 :(得分：1)
它已被贬值，但是在使用prog_uint8_t之前，您应该可以通过添加以下代码来使其工作
#define __PROG_TYPES_COMPAT__
#include <avr/pgmspace.h>
typedef uint8_t PROGMEM prog_uint8_t;
答案 1 :(得分：0)
prog_uint8_t
此typedef由avr-libc中的（非常）旧的标头提供。问题是他们在__attribute__((__progmem__))中使用了progmem是变量属性，而不是类型属性， avr-gcc ABI。
#define __PROG_TYPES_COMPAT__
#include <avr/pgmspace.h>
这不是解决方案：：虽然“修复”了构建错误，但由于progmem不是类型属性，因此它将调用未定义行为。由于某种原因，不推荐使用这些类型！
typedef uint8_t PROGMEM prog_uint8_t;
这不是解决方案：：虽然它“修复”了构建错误，但由于progmem不是类型属性，它将调用未定义行为。 / p>
typedef uint8_t prog_uint8_t;
这不是 解决方案：，尽管它“修复”了构建错误，但是用该类型声明的对象将位于RAM中，因此pgm_read_xxx()用于从闪存读取数据/程序存储器将读取垃圾，因为数据位于错误的地址空间中。原则上，您可以使用该typedef并使用普通的C ++访问，而不是通过pgm_read_xxx进行读取，但这不是您想要的，因为引入了PROGMEM，将const变量放入闪存而不是RAM中。这是因为对于大多数AVR，.rodata位于RAM中而不位于闪存中。请参阅下面的注释。
正确的解决方案是对先前使用这些可怕的编类型的所有对象定义使用PROGMEM定义的#include <avr/pgmspace.h>：
const uint8_t array_flash[] PROGMEM = { 1, 2 };
代替错误的
const prog_uint8_t array_flash[] = { 1, 2 };
由于您使用的是C ++，因此__flash之类的地址空间不可用，我不再赘述。
注意：有些AVR设备具有线性地址空间。对于此类设备，.rodata 位于闪存中。这意味着对于此类设备，使用PROGMEM + pgm_read_xxx没有优势；相反，您只是在编写可移植性差，难以阅读和维护的代码。相反，请使用香草C ++。
avr-gcc documentation中列出的设备家族为avrtiny和avrxmega3。
