    Hello,

    I was trying to use Epoll pacakge for my nodejs app to detect GPIO2_5 (pin #11 rightmost). But I ran into an error after few seconds of starting the nodejs app:

    I posted an issue to the Epoll repository. But the author redirected my to espressobin forum saying it might not be related to Epoll package: https://github.com/fivdi/epoll/issues/25

    The problem maybe related to MMC. So I tried to use the GPIO’s in the left side of the board (P9). But, from what I can observe, the GPIO’s in the left side makes the board unresponsive and hangs.

    Most of the people do not wait the timeout hardware interrupt as they make the nursing assignment help UK best for getting the highest marks.
