[chirp_devel] Need help with UV-5R reading/writing

[Les Niles]

Jim,

In that case, what I suggested won't work.  Especially if the mapping is non-uniform, that is, the freq steps are all integer multiples of the smallest step.

Maybe you just need to divide the index by 16 when you access STEP_LIST: 
>> RadioSettingValueList(STEP_LIST,
>>                                                     STEP_LIST[self._memobj.vfoa.step/16])


Or maybe a dictionary rather than an array would work better:
	STEP_LIST = {0x0: 2.5, 0x10: 5.0, 0x20: 6.25, … }

It's hard to tell what the best method would be, without seeing all of the related code.  And no, I'm not asking to join the UV-5R driver team. :)
