Is there any documentation or folk wisdom about the interrupt handling performance
of Mongoose on the ESP8266 ? I've been experimenting with this in init.js with limited
success, but it would be easy enough to move it to C if that would help.
Suppose I have handlers on a couple of GPIO lines, and I want to watch all the transitions.
I can attach the handler, but when it gets invoked I don't know the sense of the transition so I have to call GPIO.read.
How much latency am I likely to see between the transition which causes the interrupt and the read ?
If a couple of interrupts happen in close proximity, what happens ? What does close mean here: ms, us?
Thanks in advance.
