올려주신 예제로 해보있는데 잘안돼서 질문드립니다.
아두이노 레오나르도 버전을 사용하고있습니다.
#include <TimerOne.h>
const int pin_LED0 = 5;
const int pin_LED1 = 6;
const int pin_LED2 = 8;
const int pin_LED3 = 9;
const int pin_LED4 = 10;
const int pin_LED5 = 11;
const int pin_LED6 = 12;
const int pin_LED7 = 13;
byte led_pinlist[14]={5,6,8,9,10,11,12,13,12,11,10,9,8,6,};
int pin_SW1=3;
int dir=0,index=0,cnt=0,flag=0;
void setup(){
pinMode(pin_SW1,INPUT);
pinMode(pin_LED0, OUTPUT);
pinMode(pin_LED1, OUTPUT);
pinMode(pin_LED2, OUTPUT);
pinMode(pin_LED3, OUTPUT);
pinMode(pin_LED4, OUTPUT);
pinMode(pin_LED5, OUTPUT);
pinMode(pin_LED6, OUTPUT);
pinMode(pin_LED7, OUTPUT);
Timer1.initialize(1000000);
Timer1.attachInterrupt(blinky);
Serial.begin(9600);
// pinMode(10,INPUT_PULLUP);
}
void loop(){
uint8_t SW_1_data;
SW1_data = digitalRead(pin_SW1);// 스위치1번을 눌렀을때 점멸 진행방향이 바뀌고싶습니다
if(!digitalRead(10)){
if(flag==0){ flag=1; dir^=1; }
}
else flag=0;
delay(100);
}
void blinky(){
if(dir==0){ if(++index>13)index=0; }
else { if(--index<0)index=13; }
//
for(int i=0;i<14;i++)pinMode(led_pin[i],OUTPUT);
digitalWrite(led_table[index],HIGH);
}

올려주신 예제에서 pin번호만 바꾸어서 돌려봤는데
#include <TimerOne.h>
^
compilation terminated.
exit status 1
보드 Arduino Leonardo 컴파일 에러.
라는 에러도 뜹니다.

다운로드해서 라이브러리에 적용후 돌려봤습니다.
sketch_jun14a:42: error: 'led_pin' was not declared in this scope
for(int i=0; i<14; i++)pinMode(led_pin[i],OUTPUT);
^
sketch_jun14a:43: error: 'led_table' was not declared in this scope
digitalWrite(led_table[index],HIGH);
^
exit status 1
'led_pin' was not declared in this scope
에러가 납니다.
제가 주석처리한 // pinMode(10,INPUT_PULLUP); 코드부분은 필요없나요?

led_table[index]
led_pinlist[14]
배열 이름을 맞춰주세요

배열이름도 맞춘거같은데 ㅠㅠㅠㅠ
