That's great - thanks for all the debugging work!
When JavaScript code isn't minified, it runs more slowly - so that explains how the HD44780 starts working I guess! I'll have a look at the driver, but your
digitalPulsesolution seems pretty good.For now, anyone having this problem could change the 'Module Extensions
item in the Web IDE settings from.min.js|.jsto.js|.min.js`. That'll then load in unminified modules, which should be slow enough to make the LCD start working.
