void EPWM_forceDiodeEmulationActive(uint32_t base)

Forces DEACTIVE flag to 1

Return

None.

Parameters

• base: is the base address of the EPWM module. This function is used to force DEACTIVE flag to 1.

void EPWM_enableDiodeEmulationMonitorModeControl(uint32_t base)

Enables DE monitor control mode

Return

None.

Parameters

• base: is the base address of the EPWM module. This function is used to enable the DE monitor counter function.

void EPWM_disableDiodeEmulationMonitorModeControl(uint32_t base)

Disables DE monitor control mode

Return

None.

Parameters

• base: is the base address of the EPWM module. This function is used to disable the DE monitor counter function.

void EPWM_setDiodeEmulationMonitorModeStep(uint32_t base, uint32_t direction, uint32_t stepsize)

Sets the DE monitor counter step size

Max value of stepsize is 256.

Parameters

• base: is the base address of the EPWM module.

• direction: is the direction of the monitor counter counting either UP or DOWN.

• stepsize: is the amount by which the counter increments or decrements at each step. This function is used to set the DE monitor counter step size. Valid values for direction are: EPWM_DE_COUNT_UP - Diode emulation count up step size EPWM_DE_COUNT_DOWN - Diode emulation count down step size.

Return

None.

void EPWM_setDiodeEmulationMonitorCounterThreshold(uint32_t base, uint32_t threshold)

Sets the DE monitor counter threshold value.

Max value of threshold is 2^16.

Return

None.

Parameters

• base: is the base address of the EPWM module.

• threshold: is the max value till which the monitor counter can count. This function is used to set the DE monitor counter threshold.

void EPWM_clearDiodeEmulationActiveFlag(uint32_t base)

Clears DE mode active flag

Return

None.

Parameters

• base: is the base address of the EPWM module. This function is used to clear the DE mode active flag

void EPWM_setEmulationMode(uint32_t base, EPWM_EmulationMode emulationMode)

Set emulation mode

This function sets the emulation behaviours of the time base counter. Valid values for emulationMode are:

• EPWM_EMULATION_STOP_AFTER_NEXT_TB - Stop after next Time Base counter increment or decrement.

• EPWM_EMULATION_STOP_AFTER_FULL_CYCLE - Stop when counter completes whole cycle.

• EPWM_EMULATION_FREE_RUN - Free run.

Parameters

• base: is the base address of the EPWM module.

• emulationMode: is the emulation mode.

Return

None.

void EPWM_configureSignal(uint32_t base, const EPWM_SignalParams *signalParams)

Configures ePWM signal with desired frequency & duty

This function configures the ePWM module to generate a signal with desired frequency & duty.

Parameters

• base: is the base address of the EPWM module.

• signalParams: is the desired signal parameters.

Return

None.

struct EPWM_SignalParams

#include <epwm.h>

Values that can be passed to EPWM_configureSignal() as the signalParams parameter.
