单片机数组模块化问题

ID:837401 · 发表于 2021-5-21 20:38

想把数组单独放到一个文件但是怎么编译都出错，主要是我现在不知道怎么定义外部数组
all.H文件
#include <STC8.H>
#include <intrins.H>
#include "Chinese.H"
typedef unsigned char u8;
typedef unsigned short u16;

main文件
#include "all.H"
void main
{
u8 i，j；
while（1）
{
P1=Chinese[ i][j] //假如这么写[ i]
}
}

Chinese.c文件

#include "all.H"
u8 code Chinese[3][32]=
{{0x00,0x00,0x3F,0xF0,0x20,0x20,0x20,0x20,0x3F,0xF0,0x00,0x01,0x00,0x06,0x3F,0xF8,0x22,0x00,0x22,0x00,0x22,0x00,0x43,0xFF,0xC2,0x00,0x42,0x00,0x02,0x00,0x00,0x00},/* (16 X 16 ) */{0x02,0x08,0x02,0x30,0x02,0x02,0x02,0x01,0xFE,0xFE,0x22,0x00,0x22,0x20,0x02,0x19,0x20,0x02,0x3E,0x04,0x21,0xC8,0x20,0x30,0x21,0xCC,0x3E,0x02,0x00,0x01,0x00,0x00},/* (16 X 16 ) */{0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x00,0x00},/* (16 X 16 ) *
