防反跳电路

Hello,

I want to add push button switches as a user interface in my project. So is there any protection against the switch bounce in DA14585 internally. Is there any need to add an external debounce circuit?

Thanks and regards,

Hi sr9213,

The wakeup timer as well as the keyboard scanner implement a debouncing mechanism, please have a look at the UM-B-079 da14585 586 SDK 6 Software Platform Refernce.pdf and check the functions wkupct_enable_irq() and GPIO_EnableIRQ(), those functions will allow you to set up your interrupts along with a debounce value.

Thanks MT_dialog
