Can this program be used for LPC1768?
Hi, can this program be used for LPC1768?
include "mbed.h"
class PwmIn
{
public: PwmIn(PinName p) : _p(p)
{
_p.rise(this, &PwmIn::rise);
_p.fall(this, &PwmIn::fall);
_period = 0.0; _pulsewidth = 0.0; _t.start();
}
void rise()
{
_period = _t.read(); _t.reset();
}
void fall() { _pulsewidth = _t.read();
}
float period()
{
return _period;
}
float pulsewidth()
{
return _pulsewidth;
}
float dutycycle()
{
return _pulsewidth / _period;
}
protected: InterruptIn _p; Timer _t; float _pulsewidth, _period; };
PwmOut x(p21);
PwmOut y(p22);
PwmIn a(p5);
PwmIn b(p6);
int main()
{
x = 0.5; y = 0.2;
while(1)
{
printf("a: pw = %f, period = %f\n", a.pulsewidth(), a.period());
printf("b: pw = %f, period = %f\n", b.pulsewidth(), b.period());
wait(2);
}
}
