latency tester

This is a little Arduino gadget using the Adafruit Feather M4 Express board

It just measures the time between and stop triggers, and prints the elapsed number of milliseconds to the virtual serial port. The start trigger can be any of:

• sending the character A (upper-case A) from the host to the device over the virtual serial port (for example, /dev/ttyACM0)
• voltage on the A0 pin above 1.0v (do not exceed the chip's max voltage of 3.3v)

The stop trigger is:

• sending the character a (lower-case a) from the host to the device over the virtual serial port.
