TinyDuino Processors & TinyShields / Re: GPS Accuracy

I have the external GPS antenna sold by TinyCircuits.....  Hoped for more consistent results especially when the unit is absolutely stationary.....    It's probably good enough to track cars across country but not cat/dog around yard.

My experience with the GPS shield is that it is very inaccurate.     If I leave it in one position continuously it continually updates the location data and it varies by 15 meters.   It settles down somewhat but never stabilizes on a single location. If I move to another location and come back to first location,  the location is way off.

The specs say 2.5 meters accuracy and my unit is no where near this level of accuracy.   The accuracy makes the unit worthless for my application.   I am wondering if I got a bad unit or the GPS chip specs are misleading.

Anyone else have any experience with this GPS Shield?

Can you charge Tiny Screen battery when switch is off or does the switch need to be on?

Can you use a standard USB phone charger?

Thanks

General Discussion / Re: Problem with Serial_Monitor with TinyScreen+

I found the answer in a sem-unrelated post.     

Change:
#define SERIAL_MONITOR Serial
To:
#define SERIAL_MONITOR SerialUSB

and it now works.

General Discussion / Problem with Serial_Monitor with TinyScreen+

« on: July 20, 2016, 08:41:06 PM »

I am using Arduino 1.6.9 and cannot get this very basic script to work.    I have TinyScreen+ and GPS module and am just trying to get started.    I finally found and modified a SoftwareSerial module that allowed the sample GPS code to compile but got no output. 

So,  I simplified my code to the bare minimum.   No includes whatsoever. but not output to serial monitor.

Any ideas what is wrong? 
--------------------------------------------------------------------------

#define SERIAL_MONITOR Serial


void setup()
{
  SERIAL_MONITOR.begin(115200);
  delay(100);
  SERIAL_MONITOR.print("Attempting to wake GPS module.. ");
  SERIAL_MONITOR.println("done.");
  delay(1000);
} 
 
void loop() {
  SERIAL_MONITOR.println("next done.");
  delay(1000);
}
