"rocket surgery" = "rocket science"[0] + "brain surgery"[1]
dropping: "science brain"
I always visualized it as similar to laser surgery, only with rockets instead of lasers.

Re: ILI9225 TFT display driver

Just take one of the existing drivers, take the datasheet, and make it. It's not rocket surgery. You will probably only need to make small modification to the initialization commands, everything else should be exactly the same.

Re: OpenMV M7?

what is the point of PyBoard, other than having a few more I/O channels and pins? The price is one important difference. But generally speaking, they are two completely different systems made completely different people working at different companies. PyBoard tries to be a general-purpose developme...

Re: Drivers for OLED displays and portable GUI

In case anybody finds it useful, I wrote an article about handling the small OLED displays without a library: https://hackaday.io/page/5722

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...
