I’m working on a project using Zero.
I used some buttons and led for gpio pin test in advance, but I thought there was no big problem at that time.
And even if you pull-up to make the pull-up state now, it doesn’t work.
Not only that, but I’m also curious about how to operate the pwm, so I’ll upload my source file and settings additionally.
I remember making an error that the pwm is not initialized when the Python code is used and the operation is performed.
In other words, I have two questions below.
Is zero pull-up possible? And is there an impossible pin?
How do you use the pwm of Zero? Python code, please!
