Re: Pico Micropython overclocked twice (250MHz) works fine

That firmware was linked in the opening post in this thread. Your suggestion solved the issue, thanks! (interestingly, it works for generic firmware: for firmware.250MHZ.uf2, machine.freq expects no arguments, i.e., can only be used to read the clock rate, not to modify it). Thanks again for your he...

Re: Pico Micropython overclocked twice (250MHz) works fine

Programs are indeed running x2 faster with firmware.250MHZ.uf2. Thanks for providing this! One observation: this is true if the program is launched from Thonny (Thonny can then be closed and the program keeps running fast). However, the same program saved as main.py and launched by just powering the...

Re: method __missing__ not working for dictionary in Conway's game of life

For reference, I solved the issue by dropping __missing__ and using instead

Code: Select all

    def __getitem__(self, key):
        return self.get(key,0)
A similar approach with __missing__ did not work. Whatevs.

Re: method __missing__ not working for dictionary in Conway's game of life

PS: in another forum someone tested the code against CPython, and the error was not reproduced. If this is micropython specific, why is there no complain when invoking the __missing__ method, but instead it just does not work? Unfortunately the information about micropython's treatment of dictionari...

method __missing__ not working for dictionary in Conway's game of life

Apologies for my ignorance, I am completely new to micropython. As such my first foray is trying to implement code for Conway's game of life on a Raspberry Pi Pico using an 128x128 oled. I figured out how to do this using "brute force" (i.e., 128x128 matrices) but the optimized speed, even overclock...
