LoPy - oscillator frequency

[m.toriello]

Hi there,
is there any chance to set in code the internal oscillator frequency of the LoPy4?

Thanks in advance

Ok, thank you!

Best regards

Thanks @m-toriello

The LoPy4 uses a ESP32 microcontroller where the clock is driven from an external crystal. If you program it directly in C (using ESP-IDF) you can select different clock speeds at configuration (80, 160, 240 Mhz) but - because of the many timing critical peripherals implemented - in MicroPython this isn't currently supported and the clock is fixed at 160Mhz.

Hi @jmarcelino ,
I mean the microcontroller's oscillator. For example the Microchip PICs hve some registers to set the internal oscillator properly (typically it's called INTOSC). I was wondering if there is something like this in LoPy.

Thank you

Hi @m-toriello
Which internal oscillator do you mean exactly?

Thanks
