I configured a cyw20719b2 pin to falling edge interrupt, and found that the interrupt response time is 59 microseconds.
Is there and method to make the interrupt response time as short as possible?
Solved! Go to Solution.
1) At the beginning of Interrupt Service Routine(ISR), a wiced_hal_gpio_set_pin_output() set a GPIO high, at the end of ISR, a wiced_hal_gpio_set_pin_output() set the same GPIO low. And read the response time from a oscilloscope.
2)I would like to receive data from a peripheral chip.
