Hello Cypress
I am using a Timer Counter with a clock of 1 MHz. My frequency is 20 Hz (50,000 counts). When its unitl a value it trigger an output and after it needs to change the output again. But what it is happening is that is not restarting again and Ive programmed it as continous. My interrupt is trigger just once.
here is my code of initalizing the timer:
Cy_SysInt_Init(&Triger_ISR_cfg,&TimerTreatmentInterruptHandler);
NVIC_EnableIRQ(Triger_ISR_cfg.intrSrc); /* Enable the core interrupt */
__enable_irq(); /* Enable global interrupts. */
/* Start the TCPWM component in timer/counter mode. The return value of the
* function indicates whether the arguments are valid or not. It is not used
* here for simplicity.
*/
(void)Cy_TCPWM_Counter_Init(Counter_1_HW, Counter_1_CNT_NUM, &Counter_1_config);
Cy_TCPWM_Enable_Multiple(Counter_1_HW, Counter_1_CNT_MASK); /* Enable the counter instance */
/* Set the timer period in milliseconds. To count N cycles, period should be
* set to N-1.
*/
Cy_TCPWM_Counter_SetPeriod(Counter_1_HW, Counter_1_CNT_NUM, cycleTime - 1);
Cy_TCPWM_TriggerStart(Counter_1_HW, Counter_1_CNT_MASK);
the interrupt function code:
o++;
DBG_PRINTF("Enter how many time %x\r\n", o);
/* Clear the terminal count interrupt */
Cy_TCPWM_ClearInterrupt(Counter_1_HW, Counter_1_CNT_NUM, CY_TCPWM_INT_ON_TC);
/* Toggle the LED */
if (triggerValue == TRIGGER_LOW)
{
DBG_PRINTF("TriggerValue %x \r\n", triggerValue);
triggerValue = TRIGGER_HIGH;
Counter_1_SetCounter(dutyCycleOn);
}
else
{
DBG_PRINTF("TriggerValue %x \r\n", triggerValue);
triggerValue = TRIGGER_LOW;
Counter_1_SetCounter(dutyCycleOff);
}
if (treatmentActive == ON)
{
Trigger_Write(triggerValue);
cycleCounter++;
if (cycleCounter >= 2* onCycles){
treatmentActive = OFF;
cycleCounter = 0;
DBG_PRINTF("Treatment finsih at: ");
CtsPrintCurrentTime();
DBG_PRINTF("\r\n");
}
else if (cycleCounter == 1)
{
blickControl = ON;
}
if ( blickControl == ON)
{
Treatment_On_INV();
CyDelay(100);
}
else
{
Treatment_On_Write(LED_OFF);
}
}
else
{
Trigger_Write(TRIGGER_LOW);
Counter_1_SetCounter(0);
treatmentActive = ON;
blickControl = OFF;
}
there is a method to restart the Timer?
