ＺＣＤライブラリ。これもシンプルなので説明の必要がないかな。

【サンプルコード】

#include "avr8_zcd.h"

Zcd zcd0(ZCD0);

void func(Zcd::STATUS status)
{
  if (status & Zcd::STATUS_CROSSIF)
  {
    /* cross */;
  }
}

int main(void)
{
  zcd0.begin();
  zcd0.callback(func);
  zcd0.intctrl(Zcd::INTMODE_BOTH);
  while (1)
    Zcd::poll();

  return 0;
}

#include "avr8_zcd.h"

Zcd zcd0(ZCD0);

void func(Zcd::STATUS status)

{

if (status & Zcd::STATUS_CROSSIF)

{

/* cross */;

}

int main(void)

{

zcd0.begin();

zcd0.callback(func);

zcd0.intctrl(Zcd::INTMODE_BOTH);

while (1)

Zcd::poll();

return 0;
