Re: MicroPython running "bare metal" in the browser via unicorn.js

Let me tell you a story. I have worked in embedded systems all my life, mostly in assembly, sometimes in C (with inline assembly) or FORTH. Some of my designs have gone into production at a rate of 100,000 per hour. For those projects that have lower volumes. over time I have migrated from the 6502/...

Re: Large color LCD?

Re "I don't understand your application, but on the face of it, it would seem simplest to do the editing on the Pi and communicate the resultant text to the Pyboard via a UART."
