- Tue Oct 21, 2014 5:51 am #1802 HI All,
I have a bunch of sensors I'd like to be able to monitor and I've been looking at these little wonders and would like to know: Does it have the resources to:
a) Have an Interrupt configured detect a GPIO transition
b) On receiving the interrupt, make an HTTP call to a server?

Thanks in advance

I don't want to be human! I want to see gamma rays, I want to hear X-rays, and I want to smell dark matter ...
I want to reach out with something other than these prehensile paws and feel the solar wind of a supernova flowing over me.

Where would I start looking to understand how interrupts are handle on the chip? I can't see any examples thus far.

Thanks,

AB

- Fri Oct 31, 2014 9:17 am #2097 I played a bit with the commands but was not able to enable the interrupts.
Thats the reason I am currently have a timer set up which is polling the pin... NAAAAH!!!

I did some research on that and found:

I haven't had the time to try those commands but maybe someone wants to do it and post an explanation?
Seems like there is just one GPIO interrupt handler and that you have to figure out what happened in the ISR, but this is just speculation, I look forward to get some Infos on that

For sending some HTTP on an event you might want to check my AT-example mod code
