RPI Pico Speed

[amit_dav]

Greetings!!
How do I know what speed the pico is running (Operating Speed)? Also is there some way to change the clock speed to say 20Mhz or 120Mhz?


Thanks Amit

Both is possible with machine.freq().
machine.freq() returns the actual setting
machine.freq(HZ-value) sets the new frequency. The suitable range is 12 - 270 MHz, but not all values in that range will be accepted.

Default system clock is 125MHz.
USB+UART+GPIO works fine for 250MHz.
You can overclock to >=420MHz with GPIO still working.
My first 3 Picos maxed out with working GPIO at 426/428/436MHz.
I was able to run Pico at 10MHz, but all frequencies below did not work.

In case you overclock with >400MHz, you can produce USB output by first setting system clock to <=250MHz, then output, finally switch back to >400MHz.

Thanks for the prompt reply! It helped a lot.

Thanks again Amit
