TIM_SelectInputTrigger(TIM5, TIM_TS_ITR0);

/* Selects the Trigger Mode as Slave Mode for TIM5 */

TIM_SelectSlaveMode(TIM5, TIM_SlaveMode_Trigger);

}

Note:

TIM2 is used by the dual FOC MC part to synchronize all timers.

In the "main.c" module:

int main(void)

{

...

#ifdef PFC_ENABLE

TIM5_Configuration();

#endif

SVPWM_1ShuntInit();

...

}

Note:

TIM5_Configuration

must be called before any initializations performed by

SVPWM_1ShuntInit()

In the "stm32f10x_svpwm_1shunt.c" module:

void SVPWMUpdateEvent_TIM8(void)

{

...

#ifdef PFC_ENABLE

TIM5->CCMR2 &= 0xFF8F;

TIM5->CCMR2 = (TIM8->CCMR2 >> 8);

#endif

...

#ifdef PFC_ENABLE

TIM5->CCR3 = TIM8->CCR4;

#endif

...

#ifndef PFC_ENABLE

ADC3->CR2 |= ADC_ExternalTrigInjecConv_T8_CC4;

#else

ADC3->CR2 |= ADC_ExternalTrigInjecConv_T5_TRGO;

#endif

...

}

Firmware modifications to set IRQ priorities

The following is the code to resolve the conflicts outlined in Section 4.2.4.

In the private define of the "stm32f10x_svpwm_1shunt.c" module:

#ifndef PFC_ENABLE

#define ADC3_PRE_EMPTION_PRIORITY 1

#else

#define ADC3_PRE_EMPTION_PRIORITY 2
