Topic: For the want of a nail ... (Read 1 time) previous topic - next topic


I saved $8  by buying an older generation Ublox GPS module ( the module I normally use has gone up in price )  and wasted basically 20 hours just to get the thing working -  for a simple clock project !

The nornal TinyGPS library doesnt work as I think this unit is so weak that it doesnt actually manage to decode a whole sentance indoors , and the checksum is wrong ?  ( The unit will be on a roof, so it might be better.  )

The time however locks on within a couple of minutes, and I have had to write a bit of code to parse just the time.
The status byte starts of as ascii 44 ( , ) and changes to   86  ( V )  ( which is supposed to be void data ) when the time locks on.

I have written some checking functions in case the time goes wrong.

If I had bought the original ones I could have been having a weekend by now !

For want of a nail the shoe was lost.
For want of a shoe the horse was lost.
For want of a horse the rider was lost.
For want of a rider the message was lost.
For want of a message the battle was lost.
For want of a battle the kingdom was lost.   And a weekend !
And all for the want of a horseshoe nail.

45 years of editing projects with a knife and soldering iron, then I found Arduino !


So how would a nail have helped in this case :)

So is your weekend worth 8 bucks?  I bet it is next time, all very well in retrospect though, you may have got both and used the $8 down the pub.
