atemage8l的arduino最小系统串口输出问题

openmmoo

atemage8l的arduino最小系统 ,采用中断方式识别红外信号，并通过串口输出。当没有红色部分时，程序输出正常，当把红色加上后，只能输出"Heard "然后不管么样按遥控都无反应。代码如下:


#define IRpin_PIN      PIND
#define IRpin          2

#define MAXPULSE 65000
#define RESOLUTION 20
#define FUZZINESS 20


uint16_t pulses[100][2];  // pair is high and low pulse
uint8_t currentpulse = 0; // index for pulses we're storing


//Received: 左
int IRsignalL[] = {
// ON, OFF (in 10's of microseconds)
