## PhotonTimingTest.ino
/*
Measurement of the FastLED.show() routine.
Soft SPI is only supported till now on the Photon.
However non-SPI pins seem to be 140us faster then when using the SPI pins.
Using those SPI pins in hardware design might be interesting for future compatibility
when hardware SPI gets supported.

Below the timing test of different pin combinations. The APA102 is updated at 16Mhz.

## udpTimeOut.ino
/*
When no packets are received Udp.parsePacket() takes 997us (about 1ms)
When a packet is received it takes 17us.

I think there is a timeout. It would be nice if we can set that with a function like: setTimeOut (like on Arduino with the Serial port).

I'd like to set it on microsecond level.

You can try this script by sending for example OSC data (I used TouchOSC).
When you receive data it displays a '/' (first character in an OSC string).
