/*Init peripherals */

DCAC_GPIO_Configuration();

DCAC_TIMx_Configuration();

DCAC_SetDeadTime(LocalDevice.Init.DeadTime);

nRet = DCAC_ERROR_NONE;

}

return nRet;

}

where:

●

DCAC_GPIO_Configuration(); is (Configuration of the GPIO pin for TIM8 timer and for

GPIO function)

●

DCAC_TIMx_Configuration(); is (Configuration of PWM timer).

This function includes the init code for the advanced timer TIM8 and GPIO.

DCAC_SendCommand(…):

This function includes the start/stop command for the output of the advanced timer TIM8

(inverter modulation).

{

DCAC_Error_t nRet;

nRet = DCAC_ERROR_INVALID_COMMAND;

if (cmd == DCAC_Start)

{

nRet = DCAC_ERROR_ON_SEND_COMMAND;

if (DCAC_GetStatus() != DCAC_Running)

{

LocalDevice.State = DCAC_Running;

// TIMx enable counter

TIM_CtrlPWMOutputs(TIM8, ENABLE);

nRet = DCAC_ERROR_NONE;

}

else

if (cmd == DCAC_Stop)

{

nRet = DCAC_ERROR_ON_SEND_COMMAND;
