I tried to synchronize Master HR timer from T1 TRGO. But cant get result.
void TIM_config(void)
{
RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);
TIM_TimeBaseStructInit(&TIM_TimeBaseStructure);
TIM_OCStructInit(&TIM_OCInitStructure);
/* Time base configuration for TIM8 and TIM1 */
TIM_TimeBaseStructure.TIM_Period = 2000; //2 * PWM_PERIOD50;
TIM_TimeBaseStructure.TIM_Prescaler = 0;
TIM_TimeBaseStructure.TIM_ClockDivision = 0;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_CenterAligned1;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Asymmetric_PWM2;
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM2;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OCInitStructure.TIM_Pulse = 1000;
TIM_OC1Init(TIM1, &TIM_OCInitStructure);
TIM_SelectOutputTrigger(TIM1,TIM_TRGOSource_Update);
TIM_SelectMasterSlaveMode(TIM1,TIM_MasterSlaveMode_Enable );
TIM_Cmd(TIM1, ENABLE);
}
void HRTIM_synchro(void)
{ HRTIM_SynchroCfgTypeDef pSynchroCfg;
pSynchroCfg.SyncInputSource=HRTIM_SYNCINPUTSOURCE_INTERNALEVENT;
pSynchroCfg.SyncOutputPolarity=HRTIM_SYNCOUTPUTPOLARITY_NONE ;
pSynchroCfg.SyncOutputSource=HRTIM_SYNCOUTPUTSOURCE_MASTER_START;
HRTIM_SynchronizationConfig(HRTIM1,&pSynchroCfg);
}
Can somebody help ?
Thank in advance
