Manufacturing test
This design will use a Bus Pirate v3 to check the output voltage of the boost converter.
- Final version should measure MCLR after VPP!
HVP Self Test Utility
Description
HVP selftest utility is intended for manufacturers to test and verify the voltage output level at the assembly line. This one should calculate the actual voltage (>12volts passes test) (49K/10K resistor divider, 3.3volt reference) taken from the Bus Pirate voltage probe measurement.

-------------------------------------------------------------------------
Usage:
hvpselftest -p device
Example Usage: hvpselftest COM1 -R
Where: -p device is port e.g. COM1
-s Speed is port Speed default is 115200

Note about this Utility
This simple selftest utility sets the buspirate to enter the binary bitbang mode first, then configure the pins as output by sending '01000000' to it, and then send '1100000' to set the power on, and send '00010100' for the voltage probe measurement, and take a reading from the 2 bytes reply.
It then power off the unit for the next test.
