Hi
Thanks for all the info - very much appreciated.
I can confirm that:
- I've been adjusting the SDA and SCL in the pins_arduino.h file
- I've selected the NodeMCU-32S device
- I'm running the same ESP32 version (1.0.6)
- I'm running the RTC library that you provided in the ZIP file
The RTC chip still can't be found.
I've attached the output of an I2C scan below:
21:53:09.314 ->
21:53:14.298 -> Scanning...
21:53:14.298 -> I2C device found at address 0x22 !
21:53:14.343 -> I2C device found at address 0x24 !
21:53:14.343 -> I2C device found at address 0x3C !
21:53:14.343 -> done
21:53:14.343 ->
It's finding the 2 PCF8574 chips and it's finding the SSD1306 display.
Normally I would expect the DS1307 RTC chip to also be listed, with an address of 0x68 but it's not showing up.
I've tried removing the SSD1306 display but in this scenario it just shows the 0x22 and 00x24 devices.
If I connect the SSD1306 display via the IIC Header and it works fine via that as well.
I tried uploading the .bin to the A6 using the esptool that comes with the Arduino IDE, but after successfully uploading it, the A6 went into a continuous reboot cycle.
I tried the BIN file again and managed to get it working.
It returns a "Couldn't find RTC" message.
