Posted on March 02, 2017 at 19:58Hello there,
I am having problems with Timers 6 and 7 configuration in STM32F0 device. What I am trying to do is to implement a way to start a timer, restart it (make it count from 0 without stopping) and stop it. Each of those actions should not trigger the update event. As for a test, I have setup my timer prescaller and period to 0xFFFF both. this should give me about 90 s time before the interrupt would trigger. I am resetting and disabling the timer in the meanwhile and even though I am getting an interrupt. What Am I doing wrong? Those are my restart and stop timer routines:
/*
* @brief Resets the rx timeout timer for specified generic struct
* @param uart: generic struct pointer
* @return HAL_OK if all ok.
*/
HAL_StatusTypeDef mbg_ResetRxTimer(mbgUart_t* uart)
{
assert_param(uart);
assert_param(uart->rxQ.toutTim);
HAL_StatusTypeDef retVal = HAL_OK;
retVal += HAL_TIM_Base_Stop_IT(uart->rxQ.toutTim); // turn off
uart->rxQ.toutTim->Instance->CNT = 0; // reset counter
retVal += HAL_TIM_Base_Start_IT(uart->rxQ.toutTim); // turn on
return retVal;
}
/*
* @brief Turns off the rx timeout timer for specified generic struct
* @param uart: generic struct pointer
* @return HAL_OK if all ok.
*/
HAL_StatusTypeDef mbg_DisableRxTimer(mbgUart_t* uart)
{
assert_param(uart);
assert_param(uart->rxQ.toutTim);
HAL_StatusTypeDef retVal = HAL_OK;
retVal += HAL_TIM_Base_Stop_IT(uart->rxQ.toutTim); // turn off
uart->rxQ.toutTim->Instance->CNT = 0; // reset counter
return retVal;
}
I would appreciate all help
