Member Function Documentation

init()

virtual Error_t pasco2::PWM::init ( )

pure virtual

Initializes the PWM.

Returns

PAS CO2 error code

Return values

OK	if success
INTF_ERROR	if error

Implemented in pasco2::PWMSW.

deinit()

virtual Error_t pasco2::PWM::deinit ( )

pure virtual

Deinitializes the PWM.

Returns

PAS CO2 error code

Return values

OK	if success
INTF_ERROR	if error

Implemented in pasco2::PWMSW.

getDuty()

virtual Error_t pasco2::PWM::getDuty ( double &  duty )

pure virtual

Gets the PWM input duty cycle in percentage.

The duty will return 0.00 if no duty is read (e.g. polling mode). In case of error, the duty value will be -1.00, and the function will return the corresponding return code for diagnosis.

Note

The read out of PWM pulses needs to be synched with the incoming PWM signals. This synchronization needs to be handled in the PAL.

Parameters

[out]

duty

PWM input duty cycle value from PWM single or train pulse average (00.00 % to 100.00 %)

Returns

PAS CO2 error code

Return values

OK	if success
INTF_ERROR	if error

Implemented in pasco2::PWMSW.
