including custom-switch support in Deviation

robca:
here is the patch I use. You will likely either need to use gcc 4.8 to build (or you can disable the standard mixer) as code space is pretty tight right now.

I have found a solution that enables run-time configuration of the switches with minimal additional code. I need to do some testing of it, But it seems to work ok for my 3x2 setup.

Note that no more than 2 switches can be supported.
That means you choose either the 2x2 3x1 or 3x2 solution and wire your Tx accordingly. You cannot have both the 2x2 and 3x2 modifications simultaneously.

I cannot test the 2x2 or 3x1 solutions, so after I check in the code, I'll ask for testers for it.

what is st2?

Ok, I've committed the code. there are several changes:
1) The new switches will come in as 'SW A' and 'SW B'. Existing switches will not be modified. This is different from any patches floating around
2) I've removed the usb page from the menu. I needed the extra space, and I think the page is redundant with booting with ENT.
3) to enable, in tx.ini near the top (before [modules]), set:
switch_cfg=3x1
switch_cfg=2x2
switch_cfg=3x2

I have only lightly tested it, and there were a lot of changes to shrink the code enough to fit on the devo7e (I'm not using gcc 4.8 yet, and wanted to keep the code under budget). It hasn't been tested at all with the 3x1 or 2x2 settings

Edit: I should note this is really experimental. I had to change all places where there is a spinbox dealing with channels, and it is quite possible they don't all work properly.

It is using B.6/C.6 and B.8/C.6 which are the only places you can connect to on the grid.

But I see a bug in the code that means it isn't working properly.

in target/devo7e/tx_buttons.c, change:
to
If that doesn't work, I'll give you a debug build that will just scan the buttons and print out on screen their state, which should help pinpointthe issue.

why do you have diodes on your switch? The 3x1 should not require that (and it likely explains why the code doesn't work, though not why the patch you were using does).

the only case you need diodes should be for the 3x2 switch. the 2x2 and 3x1 should not need a diode.

The code I've checked in uses different scanning mechanisms for the 2x2, 3x1, and 3x2. So the wiring for the 3x2 is irrelevant when discussing the 3x1. the 3x1 code should match the original patch, however, it does assume there are no diodes on the switch.

I can make it work with the diode mod you have too, but I have no idea why it is there.

I see it in cmpang's 2x2 tutorial, so I guess that is why it is there. I have no idea why he put it there though. The diode shouldn't be needed on the 3x1 or 2x2 mod. Funnily enough, looking at cmpang's post, I see I provided the patch that enables it with the diode too...go figure.

I'll provide an update that should work regardless of if the diode is there or not for the 2x2 and 3x1. For the 3x2 it is definitely needed

Ok, I just checked in new code that will hopefully get your switches working.

Note. there is a big change here.
I have created a new file 'hardware.ini' that contains all of the hardware modifications. the transmitter will not overwrite this file.
You need to move the switch settings and module settings to this file, otherwise they will not work.

There is an example version included, but also note that I changed the name of the switch parameter.
The parameter is now:(also allowed are 3x2 and 2x2)
