class DInput10Module : public Module
This class represents the 10 Digital Inputs Module connected via eMOD bus to controller module. This module has 10 independent digital inputs and the status of each one can be obtained separately. If a polling is to be performed more than once per second, it's recommended to handle function call.

DInput10Module()

~DInput10Module()
-
EmodRet init(const DInput10ModuleCallback_Type callback_func = nullptr, void *const callback_context = nullptr, const uint8_t variant = 1)
Initialize module. It is important to emphasize that init() method is mandatory to call it and must be called always after instantiating the module. It can be called several times, each of which the module is initialized again.
- Parameters
callback_func(optional) -- [in] function that will be called when a configured event occurs.
callback_context(optional) -- [in] context that will be passed to the callback function.
variant(optional) -- [in] identifies the module in case more than one module of the same type are present.
-
EmodRet init(const uint8_t variant)
Initialize module. It is important to emphasize that init() method is mandatory to call it and must be called always after instantiating the module. It can be called several times, each of which the module is initialized again.
- Parameters
variant -- [in] identifies the module in case more than one module of the same type are present.
-
EmodRet getStatus(const uint16_t DI_INPUT_mask, uint8_t *status, bool *new_data = nullptr)
Gets a digital input status.
- Parameters
input_mask -- [in] digital input number to get the status, as enumerated above in the constants section.
status -- [out] returns last received input number status (0: deactivated, 1: activated).
new_data(optional) -- [out] returns if new data has arrived since the last function call. If status has not been received yet, NO_NEW_DATA_READ is returned. Parameter is initialized inside the class.
-
EmodRet getAllStatus(uint8_t status[NUMBER_OF_DI_INPUTS], bool *new_data = nullptr)
Gets all digital input status.
- Parameters
status -- [out] returns last received input number status (0: deactivated, 1: activated) for each digital input.
new_data(optional) -- [out] it's true if new data has arrived since the last function call. If a digital input status has not been received yet, NO_NEW_DATA_READ is returned in that input. Parameter is initialized inside the class.
-
EmodRet setPulseFilterTime(const uint16_t DI_INPUT_mask, const uint32_t ms_time)
Sets the pulse filter time. All pulses with a shorter time will be discarded.
- Parameters
input_mask -- [in] digital input number to get the status, as enumerated above in the constants section.
ms_time -- [in] pulse width (in ms). Value range 0 to 2^32-1. A 0-value means disable pulse. Default value is 0.
-
EmodRet setAllPulseFilterTime(const uint32_t ms_time)
Sets the pulse filter time for all inputs.
- Parameters
ms_time -- [in] pulse width (in ms). Value range 0 to 2^32-1. A 0-value means disable pulse. Default value is 0.
-
EmodRet getPulseFilterTime(const uint16_t DI_INPUT_mask, uint32_t *ms_time)
Gets current pulse filter time.
- Parameters
input_mask -- [in] digital input number to get the status, as enumerated above in the constants section.
ms_time -- [out] pulse width (in ms).
-
EmodRet getAllPulseFilterTime(uint32_t ms_times[NUMBER_OF_DI_INPUTS])
Gets current pulse filter time for all inputs.
- Parameters
ms_time -- [out] pulse width (in ms) for each input.
-
EmodRet getPulseCount(const uint16_t DI_INPUT_mask, uint32_t *count)
Gets number of pulses occurred in an input after a reset.
- Parameters
input_mask -- [in] digital input number to get the status, as enumerated above in the constants section.
count -- [out] number of pulses.
-
EmodRet getAllPulseCount(uint32_t counts[NUMBER_OF_DI_INPUTS])
Gets number of pulses occurred in all inputs.
- Parameters
counts -- [out] number of pulses for each digital input.
-
EmodRet resetPulseCount(uint16_t DI_INPUT_mask)
Resets the number of pulses in an input.
- Parameters
input_mask -- [in] digital input number to get the status, as enumerated above in the constants section.
-
EmodRet getPulseWidth(const uint16_t DI_INPUT_mask, uint32_t *width)
Gets last pulse width occurred in an input.
- Parameters
input_mask -- [in] digital input number to get the status, as enumerated above in the constants section.
width -- [out] pulse width (in ms).
-
EmodRet getAllPulseWidth(uint32_t widths[NUMBER_OF_DI_INPUTS])
Gets last pulse width occurred in all inputs.
- Parameters
widths -- [out] an array of counts representing the last pulse width occurred in each input.
-
EmodRet configEventAtTimeInterval(const uint32_t time_interval)
Configures module for calling init callback_func at specified period.
- Parameters
time_interval -- [in] period in milliseconds. Minimum value is 500ms,
-
EmodRet switchToMode(const uint16_t DI_INPUT_mask, const uint32_t mode)
Usually, this function only needs to be called at the beginning in the configuration stage.
- Parameters
input_mask -- [in] digital input number to be configured.
mode -- [in] desired mode for the input; PULSE_COUNTER or PULSE_WIDTH as enumerated above in the constants section.
-
EmodRet configEventOnNewData()
Configures module for calling init callback_func when new data on input occurs.
-
EmodRet configEventOnValueChange(const uint32_t threshold, const uint32_t event_mask = DI_ALL_INPUT)
Configures module for calling init callback_func when input changes its value by a specified amount, accordingly to the configured mode (see switchToMode).
- Parameters
threshold -- [in] amount of COUNT_PULSE's or miliseconds PULSE_WIDTH that triggers the event.
event_mask -- [in] bit mask representing inputs that must trigger the event.
