Doc ID 023556 Rev 1

if (DCAC_GetStatus() != DCAC_Stopped)

{

LocalDevice.State = DCAC_Stopped;

TIM_CtrlPWMOutputs(TIM8, DISABLE);

// TIMx disable counter

nRet = DCAC_ERROR_NONE;

}

return nRet;

}

where:

●

TIM_CtrlPWMOutputs(TIM8, ENABLE);

is (Enables TIM8 timer for DCAC section

and starts DataSensing acquisitions)

●

TIM_CtrlPWMOutputs(TIM8, DISABLE);

is (Stops TIM8 timer and stops

DataSensing acquisitions).

DCAC_SetPulse(…):

This function sets the PWM pulse value produced by the calculations of the closed loop

control. It is called by the microcontroller each control cycle after board startup.

DCAC_Error_t DCAC_SetPulse(u32 PulseChannel1, u32 PulseChannel2)

{

DCAC_Error_t nRet;

TIM_SetCompare2(TIM8, PulseChannel1);

nRet = DCAC_ERROR_NONE;

return nRet;

}

where:

●

TIM_SetCompare2(TIM8, PulseChannel1);

is (Set the pulse value of the TIM8

in the capture compare register).
