On TimerCameraX, RTC and camera are connected to ESP32 using different I2C buses, this means ESP32 uses two different I2C master for RTC and camera.

I'm trying to use Timer Camera X with RTC wakeup.
By enabling RTC by TimerCAM.begin(true), it resuls in camera initialization error. This problem is also reported on GitHub's issue.
By reading library source codes, this seems to be caused by I2C driver, where camera uses I2C as SCCB, while RTC also uses I2C.

Any advises?

I'm using MicroPython on UI Flow 1.3.0 beta. It seems to MicroPython is now based on 'officical' MicroPython, not on LoBo-version as in UI Flow 1.2.3.
I used the module of "wifisetup" and "machine.rtc" in the previous version, that is not available on UI flow 1.3.0's MicroPython.
Is there any plan to import these modules to UI flow's MicroPython?
I may use "network" module instead of "wifisetup", however, I have no idea what to use instead of "machine.rtc"...

@m5-docs Thanks, mine's version is: "MicroPython ESP32_LoBo_v3.2.24 - 2018-09-06 on M5Stack with ESP32", that is distributed for UI flow 1.2.3.
I burned UI flow 1.3.0-beta, and found machine.lightsleep() is available.

No, my question is NOT solved yet...

@m5-docs No, I'm using the newest MicroPython on M5stack, but "machine" has no member of "lightsleep()".

@kat Thanks, this seems to be software-counting clock in main loop. I'm looking for background-counting clock...

We can use DeepSleep mode on MicroPython as described here:
https://github.com/loboris/MicroPython_ESP32_psRAM_LoBo

Is there any way (modules) to handle light sleep mode in MicroPython?
Other version of ESP32's MicroPython provides machine.lightsleep().

In MicroPython, we can use built-in RTC as clock, such as NTP clock.
Is there any way (library) to handle built-in RTC as clock on ArduinoIDE?
