试验的一个16乘16的点阵仅仅显示两个汉字。用两个74HC164和两个74HC595移位寄存器 采用串入并出的方式 为什么 无法显示程序看了很长时间了 感觉并没有什么逻辑错误啊 还请大神求解下 谢谢啦 #include
#include
#define uchar unsigned char #define uint unsigned int #define dataout P3 sbit ds=dataout^0; sbit shcp=dataout^1; sbit stcp=dataout^2; sbit ab=dataout^3; sbit sck=dataout^4; uchar word[32]; uchar code dis[]={0x00,0x10,0x11,0x12,0x14,0x18,0xF0,0x17,0x10,0x10,0x10,0x10,0x10,0x10,0x00,0x00, 0x00,0x04,0x88,0x90,0xA0,0x82,0x81,0xFE,0x80,0x80,0xA0,0x90,0x88,0x04,0x00,0x00}; uchar code wu[]={0x00,0x00,0x00,0x00,0x01,0xe0,0x07,0x80,0x01,0x00,0x01,0x60,0x03,0xf0,0x1f,0x00, 0x02,0xc0,0x04,0x80,0x08,0x80,0x18,0x82,0x20,0x86,0x00,0x7e,0x00,0x00,0x00,0x00}; void output(uchar); void display(); void delaydis(uchar); void delaydis(uchar timer) { uchar i; while(timer--) { i=24; while(i--) display(); } } void output(uchar dat) { uchar i; for(i=0;i<8;i++) { shcp="0;_nop_(); " ds="dat&0x01; " shcp="1;_nop_(); " dat="dat">>1; } } void display() { uchar i; ab=0; for(i=0;i<16;i++) { sck="0; " stcp="0; " _nop_(); output(~word[2*i+1]); output(~word[2*i]); sck="1; " stcp="1; " _nop_(); ab="1; " } } void main() { uchar i; while(1) { for(i=0;i<32;i++) word
