General • Re: Differences between pico 1 and 2, and onewire problems

$

What do we know:
1. We know that the 1-wire protocol relies on regid timing requirements.
2. We know that the default System Clock for the Pico is 133 Mhz
3. We know that the default System Clock for the Pico is 150 Mhz
4. We know that some 1-wire drivers are poorly designed in terms of handling slight variation in timing signals.

Perhaps the driver you are using is not handling differences of system clock properly.
1. So, change the clock frequency of the Pico2 to 133 Mhz, to see if that solve the problem.
2. Try different drivers, as they are not created equally regarding the ability to handle timing deltas.
