[chirp_devel] New developer for IC-V80

[Dan Smith]

Hi Drew,

> I’d like to help by working on a driver for my IC-V80 HT.  How to start?

What platform are you on? Windows? If so, get started with these
instructions:

Once you're able to run chirp directly from the source tree, you can
start work on a driver. Take a look at the template driver for a start,
which is in chirp/template.py. Also look at some of the other Icom
drivers, since they share a lot (like all of the clone code). You may
want to start by taking something similar and simple, like the ict8.py
file as a starting point. Copy that to icv8.py and change the names
within the file. Simply doing that will cause the new model to show up
in the download box.

Here is the rough set of steps after that:

1. Figure out what the model identifier for that radio is. This can be
done by trying to download it and watching the debug log to see what it
finds from the radio. Change the _model in your driver to match.

2. Figure out what the size of the device's memory is. Do this by
setting the memsize in your driver to something large and trigger a
download. The debug log will tell you what the last address was before
the radio stopped sending.

3. Capture the "end frame" from the end of the clone process in the
debug log during step 2, and adjust in your driver appropriately.

4. Now you should be able to get a clean download from the radio. Save
that to a .img file and start examining it in a hex editor. Depending on
how the radio is designed, this may be obvious, or it may require doing
a series of changes on the radio, followed by a download, followed by
looking at the hex dumps. You'll be modifying the MEM_FORMAT structure
definition in your driver file to tell it where and how the memories are
laid out.

Once you get to step 4, we may be able to help you spot some common
Icom-isms to get you started.

Make sense?
