ESP32 Forum

Hi everyone,

I want to intergrate the ESP32-S2-MINI-1 module to my design. My design requires 18 external interrupts and looking the datasheet of the ESP32-S2-MINI-1 module I see that there are available 25 gpios. However what it is not mentioned is what gpios can be used as external interrrupts... I should assume that every gpio could be used for this purpose?

With that been said could I use any of the IO pin as external interrupt? The following capture is from the datasheet



Thanks
Nick

Anyone?

From what I can read in the TRM, yes. Each IO pin has an IO matrix entry that allows you to enable an interrupt on it.

Thank you ESP_Sprite!!

Thank you ESP_Sprite!!

use the S2 TRM for the S2-Mini instead the C3-TRM which was linked in the post

ESP32-S2 TRM

Oops. Been doing too much with the C3 I guess, when I read 'mini', I see that chip.
