Re: Multi-threading support, sponsored by Pycom

Hi guys!

Any news on this? I'm waiting for it to come to the pyboard, as I just spent weeks debugging problems which would not have occurred if I had working threads...

Ciao,
Bob

Re: Pyboard noise

@pythoncoder I can tell you the story of my all metal Asus UX303LN laptop. It is a very high end machine and very sweet. Except that the all metal housing gathers static electricity in huge quantities. So much so that I cannot put my hands on it while typing. I spoke to Asus about this and researche...

Re: Pyboard noise

@chrismas9 Thank you so much for all the work you did in trying to help me!!! I still can't imagine that you could even find my board design, let alone study it carefully and comment it! And your post is a FANTASTIC reference that I will keep separately, like Dave said! I did the tests as you sugges...

Re: Pyboard noise

I'm not quite so sophisticated as all that is described in those docs, sigh... I am not at all an electronics expert (does it show?)...

Cheers,

Re: Pyboard noise

Thanks @dbc. I also doubt that it would be possible to filter the ticks. As to my circuit, I did some more experiments without my circuit, in fact with nothing but the Pyboard and the amp cable: Configuration ⋅ A Pyboard sitting on an insulating mat, connected to the PC via USB, powered fr...

Re: Pyboard noise

Gentlemen PyBoarders, I have news to report. First, again let me thank you all for your immense help and support! I may have assumed that you knew my project, so let me give a few words of overview: ⋅ I use the Pyboard to drive a network of analog switches via spi. ⋅ These switch...

Re: Pyboard noise

Thanks for those 2 remarks. I am not recording or playing back, just making connections between 4 audio sources. These are on a pcb, into which is plugged the Pyboard. When I poll the pyboard accelerometers, I get a click in the audio signal. The same when I poll the adcs. I am really at a loss as t...

Pyboard noise

Hello again... As some may know, I am building an audio application with a pyboard. I have discovered that polling an adc or an accelerometer seems to generate a "click" which is picked up by my amplification circuit (not part of the project). Sadly, I poll 6 adc's and 2 accelerometers at ...

Re: bytecode not implemented error

I get it! I have added a dependency in my Makefile in the stmhal/scripts/ directory to handle any changes that would require a rebuild of mpy-cross. I've attached the Makefile if anyone cares to take a look. I run it from stmhal/scripts/ with the pyboard in dfu mode connected via USB: $ make deploy ...
