[chirp_devel] chirp_devel Digest, Vol 20, Issue 13

[Drew Vonada-Smith]

Gents,

 

Here is the image from my Icom IC-V80.  As confirmed by Icom's software, the
first two memory locations are filled, and contain:

 

1)  146.52, simplex.  No tone.  Label AAAAA

2)  146.76, offset minus, 600 KHz.  Tone, 88.5.  Label BBBBB

 

It appears to me that a memory channel is 16 bytes long.  The first two
bytes appear to be frequency / 5000, not three as in IC-T70.  So, I have
changed frequency in the mem structure to ul16.  The next two appear to be
offset / 5000, same as IC-T70 .   (I am aware of the IC-T70 changes to that
for oddball spacings, which I will later confirm are the same here.)  The
next 5 bytes are the memory label.  After that, I can start
setting/unsetting bits and figure out the other features.

 

Is it correct that CTCSS tones are usually enumerated rather than literal
values?  Where can I find the enumerations?

 

Also, since this radio does not use memory banks, do I have to strip out any
bank code and/or structures from the IC-T70 driver, or does setting:

 

rf.has_bank = FALSE

rf.has_bank_index = FALSE
rf.has_bank_nmames = FALSE

 

...take care of all that?

 

Making the changes noted to the data structure and bank definitions does not
result in the UI showing the correct frequency (it just says ERROR), so I am
not clear on what else I am missing.  Any tips appreciated. 

 

73,

Drew K3PA

Dan,

 

Thank you for explaining.  I also found I made an error and was using the
wrong driver to begin.  Some of the names are very close; ict7h vs ict70.
Got the new driver and set the things I already knew; model string, number
of memories, band limits etc.

 

Began again and got a memory size of 0xE80.  

 

Next thing: I know from the manual that the T70 uses ASCII channel labels
and had memory banks.  The V80 has neither.  Do you recommend I just delete
those items from the structure and try again, or how do you go about reverse
engineering the memory channel structure?

Right, and if you look at this:

 

> Last addr: 0e80

 

It's saying it stopped there. That's because the radio has a larger memory
than 0x0E80, and so the driver stopped because you told it to, not because
the radio refused a read. If you set the memsize to 0x10000 or something
else large, then you should see that "Last addr" change to the actual end.
The T70's size is 0x19E0, which is much larger than the

0x0E80 you told it to look for.

Well, that's your call, I didn't mean to scare you off. Writing a driver is
not trivial thing and it does require some study. I'm not a Windows
developer, but I did expect that even a power user would have familiarity
with the platform enough to search for files and redirect output. Maybe
that's a bad assumption on my part.

 

I won't push you, but I think you're pretty close to at least getting an
image of the radio. Once you do, all that is left is sifting through it
looking for the data and fields you need...
