Posted on January 05, 2017 at 10:43Hi,
I am using rotary encoder with two input i/o and i want to read the encoder pinA and pinB values with external interrupt. I am using callback function for two input PA0 and PA1. My functions are below:
In stm32f4xx_it.c:
void EXTI0_IRQHandler(void)
{
HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_0);
}
void EXTI1_IRQHandler(void)
{
HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_1);
}
and in main.c:
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
if(GPIO_Pin == GPIO_PIN_0)
{
//do something
}
if(GPIO_Pin == GPIO_PIN_1)
{
//do something
}
}
When i turn the encoder it does not works clearly, and when i debug the code, the call back function is called more than once. How can i fix it? Any adivse...
