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

Hello, I am working on the Project in which I am using ESP32 WROOM 32E and this Project will be Battery Operated.I want to implement external RTC crystal feature. As shown in attached image, R4 resistor value in the range of 5M ohm to 10M ohm. So how to choose proper value, can suggest specific valu...

Can we use ABS25-32.768KHZ-T ?
Which value for R4 is recommended? 5M or 10M?

Hello, I am working on the Project in which I am using ESP32 WROOM 32E and this Project will be Battery Operated. So my question is regarding using of External Crystal (RTC) and for that as per the Datasheet i have made connections of Crystal Oscillator and its Components. As you can see in attached...

We have developed battery operated product using ESP32-WROOM-32E. when device goes into deep sleep around 8-10uA current are flow normally. During Testing of product we face an issue which is described as below. During deep sleep of ESP32-WROOM-32E we removed battery from device so now slowly- slowl...

Hello, As ESP32 have 2 wake external source : 1. external 0 interrupt (only 1 pin and level High or Low both available) 2. external 1 interrupt (Multiple pins but All Low or any High available) I need to use Multiple Pins External Interrupt Detection with Active Low Configuration. but In external 1 ...

Hello, I disconnect both TX and RX pin of USB TTL and ESP32. But I test my issue in below cases : 1) Connect Only TX Pin(ESP32) to USB TTL RX - Have Issue 2) Connect Only RX Pin(ESP32) to USB TTL TX - No Issue 3) TX and RX both Connected to USB TTL - No Issue 4) Disconnect RX and TX both and pullup ...
