Just in case any of you like reading Arduino code, for fun or functions to copy-and-paste,
the code for my PCB that combines an ATMega328p with an Adafruit GPS and
16x2 LCD to display GPS info as it sends the PPS out the DB9 DCD is at GitHub.
It’s not exactly, say, measuring oscillator cycles (yet... ) but it’s perhaps
a good introduction for someone who’s never ever before used anything Arduino.
(And now that I’ve done more PCBs with Cypress and FTDI chips, I wish I’d put
that straight on my board instead of as a future daughterboard, but, feature creep.)
