Les,

OK. Let me try to say it another way

My STEP_LIST is a sequence of the available steps: 2.5, 5.0, 6.25, 10.0 etc.

The structure vfoa.step that I am reading from and writing to corresponds to 0x00, 0x10, 0x20, 0x30 etc.

So I'm thinking that somehow I read the value, divide by 16 and then display it in the settings tab.
Then if the user changes the setting, it get multiplied by 16 and get written back.

Do I make sense?

Jim

If STEP_LIST is a sequence of the radio memory values 0x0, 0x10, 0x20, etc., then
map(lambda x: x/16, STEP_LIST)
will return a sequence [0, 1, 2, …]
Is that what you're looking for?

What do you need to do?  If you are writing software and you need to convert
0, 1, 2, 3 ... 14 to 0x00, 0x10, 0x20, 0x30 ... 0xE0 then just multiply by
16.

0 x 16 = 0 = 0x00
1 x 16 = 16 = 0x10
2 x 16 = 32 = 0x20
3 x 16 = 48 = 0x30
.

14 x 16 = 224 = 0xE0

Is that what you need to do, or do I misunderstand your question?

Andrew,

I want to use this in a scenario similar to this to create a menu setting item for 'step'

            rs = RadioSetting("vfoa.step", "VFO A Tuning Step",
                              RadioSettingValueList(STEP_LIST,
                                                    STEP_LIST[self._memobj.vfoa.step]))
            vfopresets.append(rs)

The structure 'vfoa' has 'step' in it but the above doesn't work (out of range) because of the difference between the 0, 1, 2, 3 ... 14 vs. the 0x00, 0x01, 0x02, 0x03 ... 0xE0 (or 0, 16, 32, 48 ... 224).

This is probably simple to implement but right now I can't see the forest for the trees.

73,
Jim
