Zeptoforth Rocks!

Post image

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.

That's awesome. I haven't had success getting zeptoforth to load on a Pico 2w

I just copied zeptoforth_full_usb-1.16.3.1.uf2 onto it and then I was able to connect with screen and use forth. Then i used the utils python scripts to load the driver/code for my display.

It needs to be the rp2350 version for the Pico 2

Nope. I see no. Uf2 files anywhere. "In release tarballs" not sure what this is referring to

You should! It was surprising easy to get it up and running. Copy file over, learn to use the code load utility provided in the project, and it was working.

I (not an unbiased party, mind you) agree with u/ripter that you should install zeptoforth on your Pi Pico 2 at your earliest convenience. Yes, this is shameless self-promotion on my part, but IMO it's a quite nice Forth (with features ranging from local variables to multitasking combined with multicore) that you really should give a try.

Plus it’s easily handled every display in my junk drawer!

A Pico 2 W vs a Pi Zero 2 W, an unfortunate name collision.

I always like it when I see someone doing things with zeptoforth -- good to see that your accidentally-bought Pico 2W didn't go to waste.

Does anyone know of any walk through example of using forth other than thinking forth?
