Hello stm community,
I am working with the STM8S001J3 processor on the ST Visual Develop Toolchain.
And I use the TIM1 and the TIM2.
The Tim1 is enabled via the external port when the D port is active. It is used to work synchronously with the 50hz/230v side to switch on the system in the 0 pass. The Tim2 should simply give a pulse out of a port when it is turned on. But somehow they block each other. The configuration etc. I think that everything is correct.
If the code is not enough, then I send more lines- Thx (:
Here is the config in the main:
void TIM2_setup(void)
{
TIM2_DeInit();
TIM2_TimeBaseInit(TIM2_PRESCALER_16, 5);
TIM2_ITConfig(TIM2_IT_UPDATE, ENABLE);
}
void TIM1_Testsetup(void)
{
TIM1_DeInit();
TIM1_TimeBaseInit(160-1, TIM1_COUNTERMODE_UP, 400 ,0); //984
TIM1_ITConfig(TIM1_IT_UPDATE, ENABLE);
}
Here is the code for the INTERRUPT_HANDLER
INTERRUPT_HANDLER(EXTI_PORTD_IRQHandler, 6)
{
if(GPIO_ReadInputPin(GPIOD , GPIO_PIN_6))
{
TIM1_Cmd(ENABLE);
}
}
INTERRUPT_HANDLER(TIM1_UPD_OVF_TRG_BRK_IRQHandler, 11)
{
if(!GPIO_ReadInputPin(GPIOB , GPIO_PIN_4))
{
TIM2_Cmd(ENABLE);
GPIO_WriteReverse(GPIOA, GPIO_PIN_3);
}
if(GPIO_ReadInputPin(GPIOB , GPIO_PIN_4))
{
GPIO_WriteLow(GPIOA, GPIO_PIN_3);
}
TIM1_ClearFlag(TIM1_FLAG_UPDATE);
TIM1_SetCounter (0);
TIM1_Cmd(DISABLE);
}
