Zeptoforth running on the Pico 2 W. I have the displays and SD card drivers loading from the SD Card. Everything accessible in Forth over USB.

Still lots left to do. A case and battery is next. WiFi and Bluetooth support will come after that.

Rose disappeared around Talcott Notch Rd and Waterville Rd on Sunday June 28th 2026.
She is elderly and partially blind and deaf.
It’s not like her to wonder off, she love people and disappeared during a grill when there were lots of people around.

I got a second display running! This one gave me a lot of issues. It was a lot harder to setup and get working than the smaller OLED display.

The ST7789V driver has no preset for the non-standard 76×284 resolution, so I had to manually discover the correct axis swap (MADCTL), buffer initialization, and col/row offset math.

I accidentally bought a Pico 2 W instead of a Zero, so I tried Zeptoforth and it worked great. I was able to quickly get it running and even displaying on my tiny screen.
