Issue of PWM pin as EXT wakeup
Issue of PWM pin as EXT wakeup
I took GPIO4 as both of the PWM output and EXT signal to wake up the chip from deepsleep mode.After first time boot from reset,the PWM output works well and the chip goes into deepsleep.After the board waken up from deepsleep by GPIO4 or other gpios, the PWM would have no output.The issue could be fixed by disable the GPIO4 as the EXT trigger signal.Someone know how to fix the issue?Since I NEED the same pin have both of the functions.Thanx!
