Got Earthmate USB GPS, now what? Options

[lwong]

I took the plunge and got the Delorme Earthmate USB GPS.

The 6000 recognize it right away as "Delorme USB Earthmate". dmesg says something about

USB HID v1.00 Pointer [Delorme Publishing Delorme Earthmate] on usb 1.27.0

Now what do I do? I installed qpegps but the defualt path is

-p /dev/ttyS0 -s -4800

Is that for connection through serial cale? What should I change it to?

One good thing about the setup is that the Z can power the GPS all by itself. The bad is that if qpegps is run in 640x480 mode, it looks skewed.

Please help me set this up.

Thanks

The 2.4 kernel required patches to use the custom version of gpsd at http://trans.civil.northwestern.edu/~jay/gpsd.html

Where?

This:

The patch is retiring. Please take a look at the kernel mode driver by Lonnie Mendez. The driver is working and it is only a mater of time for it to go into the official Linux kernel tree.

Looks like he's talking about a module, however it appears that it's for 2.6.x.

This:

To use this GPS, we have two choices. The first one is to write a kernel module for this USB2Serial chip. However the current ( upto kerenl 2.6.5 ) usb2serial framework need to be patched in order to support interrupt transactions. The other approach is to utilize the USB DEVFS interface and communicate with the device directly from user space. The later method turned out to be easy.

seems to give two options:

1. patch the kernel to get over the difficulties caused by the usb2serial framework. I don't know whether this problem exists in 2.4.18, I don't know whether the code even exists in 2.4.18. I also don't know where one would find a patch (it seems to me that you would have to patch it yourself).

2. Use USB devfs (I don't know whether this is even supported on 2.4.18), even if it is, I'm afraid I'm not set up to build a kernel for anything other than a c7x0 atm anyway, however someone else may well be able to do so.

I imagine that libusb uses the USB (dev)fs so you will probably have no use for it.

Here (http://geocities.com/i0xox0i/), I read this:

There is also the EarthMate Userland Library project located here: http://emul.berlios.de
for people using Linux 2.4.x/2.6.x, Mac OS X/Darwin, and BSD.

Note the 2.4.x part.

I have provided the emul lib, and gpsd patched to use it. I've no idea if it'll work or not I'm afraid, but you can only try it out.

So you said you compiled it for OE, so what should I be using? OZ 3.5.3, Opie or GPE?

OZ 3.5.3, probably Opie, though GPE is an option - depends on what you want by way of apps, or whether you want to use an existing Qtopia (Sharp ROM) app (which will require Opie).

Take a look in the feeds and see if anything catches your eye, or ask on #openzaurus.
