This commit adds the allow(unused) attribute to functions and constants
that are not currently used. There is one warning remaining but
https://github.com/embassy-rs/cyw43/pull/23 attempts to address that
one. The constants have been moved into a module to allow the attribute
to be applied to the module as a whole.
The motivation for this is that it will hopefully make it easier to
spot new warnings that might be introduced by new, or updated code.
This commit adds constants intended to be used with the `cmd_word`
function.
The motivation for this to (hopefully) improve the readability of the
code.
This commit comments out two Timer::after calls which look like they
go together with previous instructions, but those instructions are
currently commented out, so it looks like these calls are not
currently needed.
This commit adds a comment to the setting of the iovar `bus:txglom`.
The motivation for this is that I had not heard of 'glom/glomming'
before and having a comment might help others that are not familar with
the term.
This commit add two constants and updates the comment about ALP.
It was not easy to find the definition of ALP but after searching I
found what I believe is the correct definition in section 3.3 "Clocks"
in the referenced document below.
Active Low Power (ALP):
Supplied by an internal or external oscillator. This clock is
requested by cores when accessing backplane registers in other cores
or when performing minor computations. When an external crystal is
used to provide reference clock, ALP clock frequency is determined by
the frequency of the external oscillator. A 37.4 MHz reference clock
is recommended.
