Xenon - UART and Performance

[ninjatill]

@rickkas7 wrote a program to test his serial port buffer. The examples/test in the library should help you test the speed. Check this post:

Particle Serial Interrupt

I published a library to do that. It’s a thread-based serial port buffer. You can choose the size of the buffer and read from it using the same methods you’d normally use for the hardware serial port. With a 4K buffer I was able to send data to a Photon continuously at 230400 without dropping a single byte.
