I have put together a small system of a ESP32-S2 TFT and a DS3231 RTC.
I am using Arduino 2.0.0 on a MacBookPro M1 running Monterey.
If I load and run the I2C_Scan example it returns the following information. 0x68 is the address of the DS3231.
16:51:23.100 -> Adafruit I2C Scanner
16:51:23.100 ->
16:51:23.100 ->
16:51:23.100 -> Default port (Wire) I2C scan: 0x0, 0xB, 0x68,
16:51:26.232 ->
16:51:26.232 ->
16:51:26.232 -> Default port (Wire) I2C scan: 0x0, 0xB, 0x68,
16:51:29.363 ->
16:51:29.365 ->
16:51:29.365 -> Default port (Wire) I2C scan: 0x0, 0xB, 0x68,
But if I run DS3231 example it can't find the ds3231.
16:47:24.133 -> Couldn't find RTC
16:48:37.771 -> Couldn't find RTC
Restarting and rebooting everything does not resolve the problem. The one thing that confuses me is that there are multiple RTClib files available. I have tried several of them with no difference. Which RTClib should I have installed?
Thanks, Phil Ershler
DS3231 is found by I2C_Scan but not by DS3231

Can you post clear photos showing your connections/soldering?
