Re: Compilation and RAM usage FAQ

So far the only person repeating themselves is you. Is that all you can do?

Re: Compilation and RAM usage FAQ

Is acquiring knowledge really that painful to you so you have to shy away from it and make other people do your work for you?

Re: SPI start stop latency

When you send the whole buffer all at once what happens internally is that MicroPython calls an internal C function, which does all the checks on the data types, sets up the SPI peripheral and all the buffers it needs, converts all the values it needs from Python types to C types, and then in a very...

Re: TM1640 8x8 LED Matrix

As far as I can tell, the AIP1640 is a cheap clone of the TM1640 — they are supposed to work the same way. I did some research about those chips back when the shield first appeared: https://hackaday.io/project/18120/log/60306 and I even have one, but I never got around to making a driver for it. Tha...

Re: difference in modules

I'm sorry, this came out way harsher than I intended. Of course you can start new topics! Feel free to do that when you have something new to discuss. But also try to look at the old topics first, it might save you a lot of time in the long run.

Re: difference in modules

I think that a much better plan for becoming better educated is to read the responses that are already on the forum, in the correct section, possibly using the search feature. And only if you don't find the information you look for, ask about it in a related thread. Creating your own thread should b...

Re: µGame – a Python-based handheld game console

Well done! Very nice! Let us know when it's on your tindie and I'll grab one. I'll have to start coming up with ideas for ... µGames . For now, you can build one yourself using a Feather M0 and a display module. But of course it's not as small then. The large black buttons on the V5 red board look ...

µGame – a Python-based handheld game console

I present to you a tiny little handheld game console, which you can program in Python to make your own games: https://hackaday.io/project/27629-game This is still very much a work in progress, but with the 5th iteration of the prototype I feel confident enough to show it and to ask for feedback. You...

Re: PWM on ESP8266

2 bytes is 18 clock cycles, add the protocol overhead, and you get around 32 clock cycles for this. PCA9685 works with I2C clock up to 400kHz in fast mode. That means you can do updates at 12.5kHz. That's three orders of magnitude faster than what you are currently doing.
