IO25 Issue when using External RTC 32.768kHz Crystal
Hello, I am using Arduino V1.0.6 SDK With ESP32 WROOM 32. I am currently facing issue of false interrupt in deep sleep on IO25, when external crystal is used. Is IO25 Used for external crystal debugging, or frequency output? how to disable this functionality, and use IO25 as interrupt to wakeup from...

ESP32-C6 Pin Selection Support
Hello, As, ESP32-C6 is new, we didn't find more information about pinout selection, We are using ESP32-C6-WROOM1 Module in our Project. We have a query regarding using Strapping Pins. 1) As per the Modules's Datasheet, MTMS : Floating MTDI : Floating GPIO8 : Floating GPIO9 : Pull-up GPIO15 : Floatin...

ESP32 External 32.768kHZ Crystal for RTC
Due to inaccuracy of internal RTC, I want to implement external 32.768kHZ Crystal.
So, how to implement this in Arduino code.
From Searching I found I need to recompile some libraries, but these posts are old, so, Is there any update to do this.
Thank You

Re: ESP32 External RTC crystal Component Selection
Can we use ABS25-32.768KHZ-T ?
Which value for R4 is recommended? 5M or 10M?
