I read somewhere here to use an SDK call for getting a CPU timer, but fail to find it again. Anyone remember this post?

I found the following on https://github.com/esp8266/Arduino/blob ... ference.md:

Code: Select allESP.getCycleCount() returns the cpu instruction cycle count since start as an unsigned 32-bit. This is useful for accurate timing of very short actions like bit banging.

Does that help?

Yep that's it, thanks! I forgot where I saw it.

Will try the coming week to replace the current pulse-timing using micros() with getCycleCount and test if this makes my code more reliable in receiving 433Mhz pulse trains.

I tried the fuzzilogic code for the reception of 433 mhz rf remotes. I didn't get the example ShowReceivedCode (RemoteSwitch) to work.

Same result here, did not work for me either. Attached my RF receiver to ESP8266-GPIO2 and changed the sketch accordingly.

Update 25-07-2015.
After installing the Latest Stable release (dated 23 jul 2015) from ESP8266-Arduino I re-tested the ShowReceivedCode (from RemoteSwitch) and this works now!!

Also tried the ShowReceivedCode example (from NewRemoteSwitch) but had no success there (yet).
