igotu2gpx

How much memory does the logger have?

Asked by Rob Fisher

When I run igotu2gpx info I can see: Number of points: 1110. Is there a way to tell the total number of points that the device can store? (Oddly, neither the MobileAction website nor the .chm manual have much to say about this.)

Trying to answer my own question now; hope you don't mind.

Looking at IgotuControlPrivateWorker::purge, there seem to be a number of blocks of 0x1000 bytes (?). The GT100 has 0x80 of these (so 512KB), the GT-120 has 0x200 (so 2MB) and the GT-200 has 0x100 (so 1MB) of memory.

Looking in igotupoints.cpp, records seem to be 32 bytes long. That gives:

GT-100: 16,384 records
GT-120: 65,536 records
GT-200: 32,768 records

I've made a few assumptions so I can imagine being out by a factor of 4 or by a few blocks (if not all of the blocks are used for records).

Does that sound about right?

By the way, the availability of this open source software is the whole reason I bought this device. I hope the manufacturers are thankful. I am!

Not sure where you were looking on the Mobile Action site. The below values are taken from the specs on the website:

GT-120:
Build-in memory 16Mb
Waypoints 65,000

GT-200e:
Build-in memory 64Mb
Waypoints 262,000

Thanks - I don't know where I was looking either.
