Blink status led if there's no input in more than (2 * NUM_INPUT) ms. That's
useful to show the user that the program is working, but not receiving proper
input.
That code for serial configuration was not really setting TXSTA register, since
the selected bank is 2. Looking at the datasheet, it seems that we were
actually messing with a register named VRCON (full name "VOLTAGE REFERENCE
CONTROL REGISTER").
This is probably a leftover from a copy/paste, since the same is done (in the
right place) previously.
This patch adds the assembly source code for the PIC firmware responsible for
processing PWM input from the RC Receiver and pushing the values to the serial
output.
