main local Lib with Clock control, creating 'long term ±0.1 sec accurate Arduino clock'
|
|
|
|
tested hardware:
|
|
-Arduino Nano 5V ATmega328P
|
|
-see local *.h files for other hardware
|
|
|
|
main functions:
|
|
- Sync RTC with GPS in UTC using interrupt
|
|
- LED blinking in sync with GPS PPS, to check accuracy
|
|
- LED ON if RTC synced in last hours
|
|
- Convert to Local Date/Time
|
|
- Setting flag for printing new time to display, using interrupt
|

/***** Notice *******************************************
|
|
!! GPS & USB use the same serial port !!
|
|
you will have to disconnect the Arduino RX pin 0 from
|
|
the GPS TX pin, to upload a new sketch over USB
|
|
->remove GPS PCB or Nano PCB from main PCB/breadboard
