• 碎花布星系的一只羊:第四节用while更好写嗷！ noTone(7)； while(digitalRead(10)==LOW) { tone(7,2093); } while(digitalRead(9)==LOW) { tone(7,2349); } while(digitalRead(8)==LOW) { tone(7,2637); } 亲测有效
• 会打枪的小西瓜:class LedSegmentDisplays { private: int ports[8]; int digits【10】[8]; public: LedSegmentDisplays(int a,int b,int c,int d,int e,int f,int g,int h) { ports[0]=a;ports[1]=b;ports[2]=c;ports[3]=d;ports[4]=e;ports[5]=f;ports[6]=g;ports[7]=h; int digits_copy【10】[8]={ {1,1,1,1,1,1,0,0},//0 {0,1,1,0,0,0,0,0},//1 {1,1,0,1,1,0,1,0},//2 {1,1,1,1,0,0,1,0},//3 {0,1,1,0,0,1,1,0},//4 {1,0,1,1,0,1,1,0},//5 {1,0,1,1,1,1,1,0},//6 {1,1,1,0,0,0,0,0},//7 {1,1,1,1,1,1,1,0},//8 {1,1,1,1,0,1,1,0},//9 }; for(int i=0;i<8;i++) pinMode(ports[i],OUTPUT); for(int i=0;i<10;i++) for(int j=0;j<10;j++) digits[i][j]=digits_copy[i][j]; } void noLight() { for(int i=0;i<8;i++) digitalWrite(ports[i],LOW); } void d(int digit) { for(int i=0;i<8;i++) digitalWrite(ports[i], digits【digit】[i]); } };
• 甜椒配大饼:感谢UP主，收获很大哦(°∀°)ﾉ
• LYT_Dr:好感慨啊，几年前入门的时候学arduino，再看真的蛮简单的，现在又刚开始学FPGA，入门真的有点难啊！按键双稳态程序去抖需要有限状态机，写595时序、iic、spi等协议都需要线性序列机，一切都为以后使用FPGA的超高速做准备，真的好累！我好怀念当年学单片机的时光啊！！
