Customer:
Is it possible to get a PPS signal from your GNSS breakout with easyC? If so, how? What is the UPDI pin for, as I cannot find any information about it?
da li je moguće dobiti PPS signal sa vaše GNSS pločice sa easyC? Ako da, kako? Čemu služi UPDI pin pošto ne mogu pronaći nikakve informacije o tome?

The easyC breakout board provides all functionality described in this example: Soldered-GNSS-L86-M33-Arduino-Library/examples/easyC/L86_M33_easyC_Full_Example/L86_M33_easyC_Full_Example.ino at main · SolderedElectronics/Soldered-GNSS-L86-M33-Arduino-Library · GitHub
It already decodes the PPS signal and finished GPS data can be read from it. For the PPS signal, there is an LED on the board that will light blue when the PPS signal is being received via the antenna. This takes about ten seconds after powering on the board, and requires a good antenna and good signal reception.
The UPDI pin is for programming the ATTINY microcontroller that reads and decodes data from the GNSS chip. It sends this data to the main microcontroller via I2C (easyC) communication.
ta easyC pločica omogućuje sve funkcionalnosti koje su opisane u ovom primjeru: Soldered-GNSS-L86-M33-Arduino-Library/examples/easyC/L86_M33_easyC_Full_Example/L86_M33_easyC_Full_Example.ino at main · SolderedElectronics/Soldered-GNSS-L86-M33-Arduino-Library · GitHub
On već sam dekodira PPS signal i s njega se mogu pročitati gotovi GPS podatci. Za PPS signal, postoji LEDica na pločici koja će svijetliti plavo kada se PPS signal dobiva putem antene, za ovo treba desetak sekundi nakon paljenja pločice, s dobrom antenom i dobrim prijemom signala.
UPDI pin je za programiranje ATTINY mikroupravljača koji čita i dekodira podatke s GNSS čipa. On putem I2C (easyC) komunikacije šalje te podatke na glavni mikroupravljač.
