ai xem giúp e đoạn code quét led matrix với?

[tdm]

Nguyên văn bởi yukul

chả là e muốn dùng 595 để gửi dữ liệu ra cod.còn 138 để cáp nguồn cho hàng
code e nó đây ạ
#include <18f4520.h>
#use delay(clock=12000000)
int8 m,i;
int8 Cot1[8]={0x68,0x6c,0x66,0x63,0xff,0xff,0x60,0x60}; //H{0x36,0x36,0x36,0x7e,0x7e,0x36,0x36,0x36}
//A{0x4c,0x6e,0x33,0x33,0x7f,0x7f,0x33,0x33}
//D{0x4E,0x26,0x36,0x36,0x36,0x36,0x26,0x4E}
//T{0x7e,0x7e,0x48,0x48,0x48,0x48,0x48,0x48}
//4{0x68,0x6c,0x66,0x63,0xff,0xff,0x60,0x60}
//int8 Dong[]={0b00000000, 0b00000001, 0b00000010, 0b00000011, 0b00000100, 0b00000101, 0b00000110,0b00000111};
//int8 hang[8]={0b000,0b001,0b010,0b011,0b100,0b101,0b110,0b111} ;
#define SH PIN_A5 // clock
#define DS PIN_A3 // data
#define ST PIN_A4 // chot
int8 team;
void sen595(int8 x)
{
#bit fla=x.7;
for (i=0;i<=7;i++)
{
if (fla)
output_high(DS); //Dich 1 bit vao 74HC595
else
output_low(DS);
output_high(SH); //Tao xung Clock
delay_us(10);
output_low(SH); //tao xung Clock
x = x<<1; //Dich trai 1 bit cua Data
}
output_high(ST); //Chot 8 bit cho dau ra
output_low(ST); //Chot 8 bit cho dau ra
}



void main()
{
int8 i,j;
while(1)
{
for(j=0;j<8;j++)
{
for(i=0;i<8;i++)
{
sen595(cot1[i]);
output_a(i);
delay_ms(10); //Tao thoi gian tre
}
}


}
}

tách phần dk 74138 sang port khác:

void main()
{
int8 i,j;
while(1)
{
for(i=0;i<8;i++)
{
output_c(i);//dk 74138
sen595(cot1[i]);
// sent138(Dong[i]);
delay_ms(2); //Tao thoi gian tre
}
}
}
