Why don't you use SET_CHECKED(...)?
I stil don't like this kind of changes - and not using SET_CHECKED makes
it even worse, since that further increases code length.
The idea was to have the configuration as compact, as you can see in the
receiver config section. It's a pitty that the packet config already
needs such a huge number of exceptions due to technical reasons. We
shouldn't further extend the numbers of exceptions and shouldn't extend
the number of lines for setting a reg.
Initially this function was just like
set_rx_cfg()
{
SET_CHECKED(...)
SET_CHECKED(...)
SET_CHECKED(...)
SET_CHECKED(...)
}
It should be easy,
* to survey, which chip settings are touched, if set_rx_cfg is called.
* to survey, that all params of the rx_cfg struct are taken care of.
The longer the function gets, the harder it is, to service it.
I really would be happy, if we don't go this way.
Anyway, please keep the naming convention of rf69.c:
rf69 -set/get - action
-> rf69_set_crc_enable
Thanks,
Marcus
