救救孩子吧,一道单片机题目:使用74LS165完成并行数据到串行数据的转换,拨码开关控制数码管的显示。例如按下D0,显示0;D1显示1以此类推。啊啊啊要怎么写呀!!!!!!附上我写的代码(菜鸟乱写的)[face]emoji:051.png[/face]求解答… 。 ∧_∧。゚ ゚ (゚ ´Д`゚)っ゚ (つ / | (⌒) し⌒ #include #include #include #define uint unsigned int #define uchar unsigned char sbit SPL = P2^5; uchar code DSY_CODE[]= { 0x00,0x3f,0x06,0x5b,0x4f,0x66,0x6d, 0x7d,0x07,0x7f,0x6f }; void Delay(uint x) { uchar i; while(x--) { for(i=0;i<120;i++); } } void main() { uchar temp; SCON = 0x10; while(1) { SPL = 0; SPL = 1; while(RI == 0); RI = 0; temp=~SBUF; P0 = DSY_CODE[temp]; Delay(200); } }
