JB_05代码，星光璀璨

#include  byte keymap[70] = {0}; void setup() { pinMode (8, OUTPUT); pinMode (9, OUTPUT); pinMode (10, OUTPUT); digitalWrite(8, HIGH); SPI.begin(); delay(100); digitalWrite(9, LOW); } byte j=0; void loop() { byte l=0; int i=0; for(int k=0;k<5;k++) { int k2=0xff-((keymap[l++]>i)<<0)-((keymap[l++]>i)<<1)-((keymap[l++]>i)<<2)-((keymap[l++]>i)<<3)-((keymap[l++]>i)<<4)-((keymap[l++]>i)<<5)-((keymap[l++]>i)<<6); int k1=0xff-((keymap[l++]>i)<<0)-((keymap[l++]>i)<<1)-((keymap[l++]>i)<<2)-((keymap[l++]>i)<<3)-((keymap[l++]>i)<<4)-((keymap[l++]>i)<<5)-((keymap[l++]>i)<<6); digitalWrite(10, LOW); SPI.transfer(1<0) keymap[k]-=16; keymap[random(70)]=64; } }

流水灯，还是流水灯，多行挨行流，还可以改成蛇形流

JB_06代码，多行流水灯

#include  void setup() { pinMode (8, OUTPUT); pinMode (9, OUTPUT); pinMode (10, OUTPUT); digitalWrite(8, HIGH); SPI.begin(); digitalWrite(10, LOW); SPI.transfer(0x00); SPI.transfer(0xff); SPI.transfer(0xff); digitalWrite(10, HIGH); digitalWrite(9, LOW); delay(100); } void loop() { int i,j; for(j=1;j<16;j*=2) { for(i=1;i<128;i*=2) { digitalWrite(10, LOW); SPI.transfer(j); SPI.transfer(0xff); SPI.transfer((byte)(0xff-i)); digitalWrite(10, HIGH); delay(50); } for(i=1;i<128;i*=2) { digitalWrite(10, LOW); SPI.transfer(j); SPI.transfer((byte)(0xff-i)); SPI.transfer(0xff); digitalWrite(10, HIGH); delay(50); } } }
