Re: Questions and wish list about Pyboard D

I'm not in a position to answer this definitively but I suspect it still isn't implemented. Some years ago a user built an I2S skin and attempted an I2S implementation for the Pyboard. Alas he never completed it to the point where the code was reliable. It needs someone with C skills and a good und...

Re: ESP32 PIN.OUT voltage

The bottom line is that you can use the MCUs pins to operate switches not for supply power to drive things.

The MCU needs to switch on the power supply to your pump not power your pump :)

Re: 5x5x5 Rubik's Cube solving robot

I have optimized the robot a lot more and now have it solving the cube in 4:45mins, as far as I am aware it is the fastest 5x5x5 solving robot anyone has built so far see https://www.youtube.com/watch?v=sD4bG8hPYLQ&feature=youtu.be I have uploaded the code that drives the robot to githuib see https:...

Re: i2s compatibility

Lobo port has had some I2S stuff for a while. I did play with it a bit back when it was first released. He had a couple of nice features like using the I2S to feed the DAC via DMA to pay a WAV file with a simple amp and speaker, this is the amp that I used https://www.ebay.com/sch/i.html?_from=R40&_...

Re: 5x5x5 Rubik's Cube solving robot

Slowly making it more effient and also smoother so that I can go faster

My first attempt took over 14mins, I now have it down to 7mins. https://www.youtube.com/watch?v=dQmz-K5 ... e=youtu.be

Re: 5x5x5 Rubik's Cube solving robot

I have got my robot to the stage it can solve a 5x5x5 Rubik's Cube although it is a little slow. I will next work on optimizing all the movements.

Re: ESP32+ Waveshare 7,5" B/W E-Paper

You should be able to just download the driver with extension .py and put it on the flash storage of the board your running MP on then just simply import the module :)

Re: Help writing SPI library (FT813 lcd driver)

@OutoftheBOTS_ I saw multiple libraries and studied all of them, but that does not help me . They are following the datasheet my problem is how to implement that on micropython. @loboris I saw your port, my initial goal was to implement the library in python, instead of C with bindings, so it would...

Re: Help writing SPI library (FT813 lcd driver)

I have a screen here with this chip on it but haven't had the time to play with it yet. I do believe the creator for Gamedunio is a bit of an expert on the chip and although his tutorials and blogs are for programming it with Ardunio I assume you maybe be able to find answers for what you need or ma...
