Software updates

[Ted Edwards W3TB]

As I read of updates -- and one specifically saying K3S -- is there going
to be a difference coming between what applies to K3S and the K3 itself?

Thanks!

Ted,

There already is a difference.  K3 Utility figures out which you have
and loads the matching firmware when there is a difference.  It should
be seamless whether you have a K3 or K3S.

Hi Don,

Hold on a second. Up to this point the firmware for the K3 and the K3S has been exactly the same. The firmware figures out at run time which features are available whether it being in the K3 or the  K3S and behaves accordingly. Is there something changed here? That would really complicate things.

Knut,

The functions of the K3 and K3S are the same, and will likely remain the
same.  The differences are in the hardware, so a 2nd MCU file has been
in place for some time to allow for a change in the microcontroller used
in later K3s and the K3S.
I can envision this being expanded, not to change the functions, but to
support minor differences in the hardware.  Part of the Elecraft
"magic", such things are transparent to the user.

My point is that K3Utility sorts it all out, and does not have to be
visible to the user, because the same steps to update firmware are used.

The differences between K3 and K3S firmware features are very minor, all having to do with hardware addressing. For example, the K3S has a second attenuator section. Other than this, there is no difference in functionality.

The reason there are two different .hex files in the load package is that older K3's had a different display controller. This affects so much of the code that I build it two different ways. K3 Utility detects the controller type and loads the associated image.
