Microchip AVR8 用のライブラリを自作する。(TCB)

ＴＣＢは起動時からの経過時間とＰＷＭ８モードに対応。

しかし．．．ＰＷＭ８モードはハマッた。CCMPレジスタの読み込みに依存するコードは正常に動作しない。バグかな？

ＨＷ割込みを使うには、
[avr8_config.h] #define CONFIG_TCB_ISR 1
の設定が必要となる。

【サンプルコード (Microchip Studio)】

#include "avr8_tcb.h"

#include "avr8_clock.h"

Tcb tcb0(TCB0);

void func(void)

{

/* 500ms interval */

}

int main(void)

{

sei();

Clock::setup();

/* 起動時からの経過時間の取得 */

tcb0.begin();

tcb0.run();

const uint32_t tick = tcb0.us2tick(500000);

uint32_t t = tcb0.read();

while (1)

{

while (tcb0.read() - t < tick)

Tcb::poll();

t += tick;

func();

}

/* ＰＷＭ８ビットモード */

if (!tcb0.begin(100000, Tcb::CNTMODE_PWM8))

/* Specified frequency cannot be supported　*/;

tcb0.pwmduty(128); /* DUTY = 50% */

tcb0.output();

tcb0.run();

while (1)

continue;

return 0;

}
