Re: Unexpected behaviour when toggling GPIO pin

@jimmo, thanks for the suggestions. Let's try again! I have posted the images in the correct order below together with the links. Hopefully one or the other will work.

Re: Unexpected behaviour when toggling GPIO pin

@jimmo. This is unfortunate! I can recreate the problem by viewing the forum on an iPad that is not linked to my Dropbox account. Unlike the 'regulars' on this forum, I do not have permission to upload images to the forum, so I used my Dropbox Public folder thinking it would do the trick. Obviously ...

Unexpected behaviour when toggling GPIO pin

I was curious how fast could a TinyPICO board toggle a GPIO pin? I flashed the following code into boot.py and main.py and attached a scope to pin 26. # boot.py: does nothing # test24.py: Basic loop timing test print('\nHello. This is test 24') from machine import Pin led2=Pin(26, Pin.OUT) while Tru...

Re: Raising documentation issues

@stijn, yes, I think opening an Issue is the way to go. Thanks for the suggestion. You asked for an example of what I had in mind. This is for the MicroPython .mpy files page: First paragraph. You should mention that boot.mpy and main.mpy are not recognised by the runtime interpreter. If you want a ...

Re: Raising documentation issues

Thanks for your reply jedie, but it seems you haven't understood what I want to do.

I do not want to change any code. I just want to offer some suggestions for improving the documentation and was asking how best to do this.

Re: Raising documentation issues

Guys, I followed your advice and failed miserably. I signed in to Github, went to micropython/micropython, selected the Pull request tab and clicked the New pull request button. I then got a Compare Changes screen with the Create pull request button greyed out. What do I do now? I don't want to chan...

Re: MicroPython Startup Time

Mike, thanks for the datapoint.

Am I right in thinking your board does not have any SPIRAM?
Do you have the startup time for non-frozen pre-compiled bytecode?

Raising documentation issues

I see that the documentation has been updated over the holiday season and is much improved. Thanks guys!

However, I have noticed a few places where things are missing or more explanation would be useful.

Is there a single place where one can post suggestions for improvements to the documentation?

Re: Problem with boot.py

I am returning to this after taking a break over the holiday season. Thanks to @dhylands for your comments and suggestion. I have simplified the scenario to two files; boot.py as below and test24.py which is copied to main.py on the MicroPython board. # boot.py: does nothing # test24.py: Basic loop ...
