【求教】LED点阵显示器——基本动画实验...x新手求教
《arduino从基础到实践》书中的项目，里面有个外部库"TimerOne"，求大神给个，书上的网址没有这个资源具体错误提示如下
源代码#include<TimerOne.h>
int latchpin =8;
int clockPin =12;
int dataPin =11;
byte led;
void setup(){
pinMode(latchPin,OUTPUT);
pinMode(clockPin,OUTPUT);
pinMode(dataPin,OUTPUT);
led = B11111111;
led = B10000001;
led = B10111101;
led = B10100101;
led = B10100101;
led = B10111101;
led = B10000001;
led = B11111111;
Timer1.initialize(10000);
Timer1.attachInterrupt(screenUpdate);
}
void loop(){
for (int i=0;i<8;i++){
led= ~led;
}
delay(500);
}
void screenUpdate(){
byte row = B10000000;
for (byte k = 0; k < 9;k++){
digitalWrite(latchPin, LOW);
shiftIt(~led);
shiftIt(row);
digitalWrite(latchPin, HIGH);
row = row <<1;
}
}
void shiftIt(byte dataOut){
boolean pinState;
digitalWrite(dataPin, LOW);
for (int i=0;i<8;i++){
digitalWrite(clockPin, LOW);
if(dataOut & (1<<i) ) {
pinState = HIGH;
}
else{
pinState = LOW;
}
digitalWrite(dataPin, pinState);
digitalWrite(clockPin, HIGH);
digitalWrite(dataPin, LOW);
}
digitalWrite(clockPin, LOW);
}
就是这个程序用的TimerOne库，新手弄不会，求大神指教......老是出错，求指导邮箱[email protected] 此处有下载
