I used to just use screen on my mac, which now seemed even more tempting since i don't need a cable anymore. "Just talk to the chip", basically, seems really cool to me.
So far (a year ago) I just pasted the minified js code and saved it. Using addCached for the Modules. Worked fine. Saving is an
awesome feature, too.
However on the original Espruino pasting worked fine with flow control/buffering for me. The new one stops somewhere in the middle when pasting larger code pieces
since it's going via serial lines: Do we have/can we expect to have a functionality to send. Checksummed code, maybe in chunks, and join them on the board again? Or is there already something that works with the Web IDE that can be re-used? While it mostly worked fine there was always that bad feeling that something could have been changed during transfer. I could use echo to check each input, but that seems a bit to much feedback.
For the current problem, I have no idea. I ripped everything apart and talked to both sides vie USB-UART. Then reassembled. Then it worked. Bad wiring/breadboard, can't really say.
Something bordering on esotericism was to draw RST explicitely to Vcc. Of course it worked without that as well afterwards. So... At least the bug was expelled.
