将AVR pgm_read_byte函数添加到MiKroc (Electronica)中

Question

我在AVR V4中有一个程序，其代码如下：

#include <avr/pgmspace.h>

void nlcd_Putc(unsigned char c)
{
    unsigned char i;
    if (c>127) c=c-64;  

    for (i = 0; i < 5; i++ )
    {
        nlcd_SendByte(DATA_LCD_MODE,pgm_read_byte(&(nlcd_Font[c-32][i])));
    }

    nlcd_SendByte(DATA_LCD_MODE,0x00); 
}

因此，当我想在MiKroC中为AVR运行这段代码时，我得到以下错误：

表达式1228324未声明的标识符“pgm_read_byte”

我应该将报头avr/pgmspace.h添加到AVR的MiKroc中，还是在Mikroc中为AVR添加与avr/pgmspace.h等效的标题？

非常感谢。

通过将此代码添加到标题中：

typedef signed char                                             int8;
        typedef unsigned char                                           uint8;
        typedef signed int                                              int16;
        typedef unsigned int                                            uint16;
        typedef signed long int                                         int32;
        typedef unsigned long int                                       uint32;
