Can someone show me how to use delay in program ? I want to activate LCD. I printed my void and put it in "Printing". I use "delay(1000);" but it don't works. There are no receivied packages. Without delay it works, but with mismatch and values on LCD are false...

You can't use a delay(1000), in this period the processor is doing nothing, thus not receiving or calculating anything.

In this project, the precise timings are everything.

Try this:
in the loop function, line --> if(data == 0b00100100){
after the function valid_packet() put your function print_lcd (avoid the use of delays here)

Try to print only one line in the lcd, if you have success then try to print the second line in the lcd.

remember, no delays in the print function!!!

LCD now looks like that.

It works, I checked by serial monitor and (GPS simulated by NMEA generator, and don't have servos yet) I have about 4-5 mismatch at 70 packages. I think it will not disturb.

I think I can add also buzzer when lipo <9V.

Thanks for Your solve, but earlier I found solution


static uint32_t time;

if(millis() > time) {
time = millis() + 2000;

here is all function for LCD

}

Very cool with the LCD!

You should set it up so that if signal is lost it stores the last known GPS coordinants.
Another useful function would be to have 4 characters on the LCD reserved to display the current heading in degrees, this could also be "saved" in the event of complete signal loss, it looks like there's space after the longitude to put this in.
