[chirp_devel] Implementing Banks in CHIRP Driver

[Craig Jones]

I was wondering what "capacity" meant. So, if that's just the count, 
where is the actual linkage between the bank and the memories? Anyway, 
the Anytone model I'm working on right now is the same (each mem is 
limited to one bank, or none):

classAnytoneBankModel(chirp_common.BankModel):
"""
     The Anytone bank model, for the radios that support it, is that a 
memory
     channel can only belong to one bank at a time. There are 10 banks (A-J
     with no alternate names). The mapping is done in a block of bytes that
     correspond to the 750 memories (one byte per memory). The possible 
values
     are 0-9 (A-J) or 15 (x0F) for "off".
"""
def__init__(self, radio, name="Banks", num_banks=10, num_memories=750):
super(AnytoneBankModel,self).__init__(radio,name)
self._bank_bounds =range(num_banks)
self._mem_bounds =range(1,num_memories +1)
self._banks =[
chirp_common.Bank(self,i,string.ascii_uppercase[i]) fori inself._bank_bounds
]
defget_num_mappings(self):
returnlen(self._banks)
defget_mappings(self):
returnself._banks
defadd_memory_to_mapping(self, memory, bank):
self._radio.set_bank(memory.number,bank.get_index())
defremove_memory_from_mapping(self, memory, mapping):
self._radio.clr_bank(memory.number)
defget_mapping_memories(self, bank):
"""Returns a list of all memories assigned to the given bank"""
         memories =[]
fori inself._mem_bounds:
             bank_index =self._radio.get_bank(i)
ifbank_index isnotNoneandbank_index ==bank.get_index():
                 memories.append(self._radio.get_memory(i))
returnmemories
defget_memory_mappings(self, memory):
         bank_index =self._radio.get_bank(memory.number)
return[]ifbank_index isNoneelse[self._banks[bank_index]]

BTW, "scrabmler_code" is misspelled.
