I wired it up to my "victim" espruino, and it seems to work.
There's just one problem... The espruino doesn't actually work off of the battery (which is putting out 3.8-3.9v - it's a lithium cell). The espruino freezes the moment it's disconnected from power. I disconnected the MAX1555 (I had it connected via jumpers), and confirmed that this behavior was the same without that.
The moment it tries to run off the battery, it freezes. I did a simple blink demo, and sure enough, the moment USB came off, it stopped blinking (but the light stayed on). But the battery voltage is 3.8~3.9 (the MAX1555 slows down charging past that), which should be enough to keep the Espruino alive. Gordon - any thoughts?
