Re: New cheap OLED screen

I have it, it's a TFT. An OLED display of this resolution (and color!) would need much more electronics on the back to generate by the high voltage necessary to drive a whole row of LEDs. While the low-resolution mono OLEDs get away with a simple charge pump, and only need external capacitors, somet...

Re: New cheap OLED screen

That is not an OLED, it's a regular TFT, the same as https://www.adafruit.com/product/3787

Re: Camera integration

CircuitPython is Adafruit's modified version of the MicroPython software. It isn't "more powerful" - its intention is to be easier for newbies. Where performance is paramount it's probably best to use mainline MicroPython. Where performance is paramount it is best to steer clear from MicroPython an...

Re: smallest, basic devices

Well, if you want to use ESP8266, then ESP-03 (and ESP-07) are pretty small, and have more pins than ESP-01. Also, cheap. If you don't care about the flavor of MicroPython, you can use Adafruit's Trinket M0, which runs CircuitPython, or do what I do, and just use the SAMD21 chip directly, it only ne...

Re: smallest, basic devices

That would probably be the espruino pico.

Re: Frame buffers

1) Fast SPI transmission rate. The ESP32 is capable of 80MHz SPI rates though I'm not sure if we can achieve that in MicroPython today. If my back-of-the-envelope math is right at 80MHz a complete frame ought to take less than 10ms (100fps!). It's more complex of course - the ILI9341 I intend to us...

Re: PYB Nano V2 mini board

That looks like a much more reasonable form factor than the original PyBoard.

Re: LCD UI - M5Stack and the ILI9341

With such a large display, you are likely to have problems with memory if you use the naive approach of just drawing your ui on the display. However, if you can redesign your UI so that it can be represented as a tiled grid of similar images and some sprites, you could make use of my "stage" library...

Re: Micropython Workshop in Zürich

I'm actually not using UART anywhere in that workshop, with a library or without, and that is because MicroPython's support for UART on the ESP8266 is atrocious and certainly not anything I would recommend to beginners.
