Question

基于atmega16的16 16点阵单片机程序

程序：
# include <iom16v.h>
# include <macros.h>
# define uchar unsigned char
# define uint unsigned int
#define DS_H() PORTC |= BIT(PC7)
#define DS_L() PORTC &=~BIT(PC7)

#define clk_H() PORTC |= BIT(PC6)
#define clk_L() PORTC &=~BIT(PC6)

#define lock_H() PORTC |= BIT(PC5)
#define lock_L() PORTC &=~BIT(PC5)
uchar SBUF[32]; //定义存储段码的空间
const unsigned char sw[16] = {0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,
0x08,0x09,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F};
//汉字显示
const uchar z[]=
{
0x40,0xC0,0x40,0xFC,0x44,0xA2,0xA0,0x30,
0x18,0x14,0x12,0x11,0x90,0x50,0x38,0x10,
0x00,0x00,0x20,0x7F,0x20,0x10,0x08,0x1D,
0x05,0x02,0x04,0x0C,0x18,0x70,0x10,0x00,//*"农",0*/

0x80,0x80,0x80,0xFC,0x80,0x80,0x80,0xFE,
0x80,0x40,0x40,0x20,0x10,0x08,0x04,0x02,
0x00,0x00,0x00,0x3F,0x00,0x00,0x00,0x7F,
0x00,0x01,0x02,0x04,0x0C,0x18,0x70,0x20,//*"夫",1*/

};

}
}
void main(void)
{

PORTA = 0x00; //PA端口控制154
DDRA = 0x1F;
PORTC = 0x00; //PC端口控制595
DDRC = 0xF0;
while(1)
{
j=0;
for(i=0;i<16;i++)
{
send(z[j]);
send(z[j+1]);
send(z[j+32]);
send(z[j+33]);
j+=2;
delay(1);
lock_H();
PORTA = 0x10;
PORTA=sw[i];
}
}
}
显示不了啊

Answer 1

找出你要的问题就行了！

Answer 2

找出你要的问题就行了，
放太多东西出来了，不好看啊。
而且最好就是用很简单的程序试一下你的电路有没有问题，
595的用法好像有点不对劲，最后要锁存数据。
