Re: Suggestions for LCD Please

That's what confuses me

How do you do characters on a graphics display ?

If it was character based it would have to be many lines

Suggestions for LCD Please

Hello

We track balloons and I would like a text style LCD to show

Identity
Latitude
Longitude
Distance
Direction
Lock ?

Suggestions for a Pi compatible HAT that would fit a Pi that can be programmed in Python or perl ?

Re: Building a GPS tracker with Raspberry Pi

I have a GPS tracker for my car

It used a GPS / GLONASS USB GPS /dev/ttyUSB0

I use perl to open /dev/ttyUSB0

I use a 3G Wifi / Mobile cell router and let the pi camp on it

or just use my iPhone

The perl script sends lat and lon to several servers
