Example

// configure pins PD0 and PD1 as pulse input channels

pulse_in_start((unsigned char[]) {IO_D0, IO_C3}, 2);

struct PulseInputStruct pulseInfo;

get_pulse_info(1, &pulseInfo); // get pulse info for pin PC3

if (pulseInfo.newPulse & HIGH_PULSE)

someFunction(pulseInfo.lastHighPulse);

// configure pins PD0 and PD1 as pulse input channels

OrangutanPulseIn::start((unsigned char[]) {IO_D0, IO_C3}, 2);

struct PulseInputStruct pulseInfo;

OrangutanPulseIn::getPulseInfo(1, &pulseInfo); // get pulse info for pin PC3

if (pulseInfo.newPulse & HIGH_PULSE)

someFunction(pulseInfo.lastHighPulse);

static unsigned char OrangutanPulseIn::newPulse(unsigned char channel)

unsigned char new_pulse(unsigned char channel)

This function returns the newPulse flags for the specified pulse input channel and then clears them, so

subsequent new_pulse() calls will return zero until the next new pulse is received. The return value of

this fuction will be 0 only if no new pulses have been received. It will be non-zero if a new high or

low pulse has been received. You can check the type of new pulse by looking at the HIGH_PULSE and

LOW_PULSE bits of the return value.

Example

// check for new pulses on pulse input channel 0:

unsigned char newPulse = new_pulse(0);

if (newPulse) // if there has been a new pulse of any kind

doSomething();

if (newPulse & HIGH_PULSE) // if there has been a new high pulse

doSomethingElse();

// check for new pulses on pulse input channel 0:

unsigned char newPulse = OrangutanPulseIn::newPulse(0);

if (newPulse) // if there has been a new pulse of any kind

doSomething();

if (newPulse & HIGH_PULSE) // if there has been a new high pulse

doSomethingElse();

static unsigned char OrangutanPulseIn::newHighPulse(unsigned char channel)

unsigned char new_high_pulse(unsigned char channel)

This function returns the newPulse flags if there is a new high pulse on the specified pulse input channel

(i.e. the return value is non-zero), else it returns zero. It also clears the HIGH_PULSE bit of the newPulse

flag byte, so subsequent new_high_pulse() calls will return zero until the next new high pulse is received.

The LOW_PULSE bit is not changed by this function.

static unsigned char OrangutanPulseIn::newLowPulse(unsigned char channel)

unsigned char new_low_pulse(unsigned char channel)

This function returns the newPulse flags if there is a new low pulse on the specified pulse input channel

(i.e. the return value is non-zero), else it returns zero. It also clears the LOW_PULSE bit of the newPulse

flag byte, so subsequent new_low_pulse() calls will return zero until the next new low pulse is received.

The HIGH_PULSE bit is not changed by this function.

static unsigned long OrangutanPulseIn::getLastHighPulse(unsigned char channel)

unsigned long get_last_high_pulse(unsigned char channel)
