* Add HW and SW flow control option
* Fmt + warnings
* changelog entry
wrong unstable macro
* address reviews
* get away with using 1 pin only
* unnecessary function call
* Address reviews + use "byte" instead of misleading "character" (at_cmd)
* RMT: simplify/avoid a few cfg attributes
* RMT: factor address calculation into new function channel_ram_start()
* RMT: don't repeatedly read *ChannelInternal::memsize()
Moving this into separate variable greatly increases readability of the
code. It also avoids unnecessary repeated volatile reads of the
corresponding register.
* RMT: rework SingleShotTxTransaction offset calculation
This is not a big simplification yet, but will help will help with
simplifying the somewhat obscure `ram_index` calculation.
* RMT: rework SingleShotTxTransaction offset calculation, part 2
This removes the somewhat hard to parse
let ram_index = (((self.index - memsize) / (memsize / 2)) % 2) * (memsize / 2);
calculation, by resorting to the ping-pong method also used by the idf
code.
Importantly, even with the previous code, ram_index cannot in fact assume any
possible in-range value in channel RAM, but only either 0 or memsize / 2
(except at the end of a transaction, when there's no data left).
Thus we can update it via
ram_index = memsize / 2 - ram_index
such that will alternate ("ping-pong") between 0 and memsize / 2.
* RMT: error out on config.memsize == 0
* RMT: fix bogus cfg attributes
This is inside of a #[cfg(any(esp32, esp32s2))] block, so esp32s3 can
never happen: The result of nested cfg attributes was still correct, but
writing it like this doesn't make any sense.
* RMT: remove unnecessary integer literal type annotation
* RMT: remove spurious code from clear_interrupts()
- update() is known to be a no-op here
- For other chips, resetting pointers and setting mem_owner is not done
in clear_interrupts(), but in start_rx. clear_interrupts() is only used in
situations where either the channel was unused before (i.e. should be
stopped), or we explicitly called Self::stop() before. Thus, match
other chips here.
* RMT: clear mem_owner in start_tx
While I haven't seen this happen, it appears to be possible that one of
the subsequent channels (or even the current channel) was used for RX before.
Thus, ensure that mem_owner is set correctly for TX.
* RMT: small refactoring
There should be no functional change, but this should make it even more
obvious that the return value is exactly the number of codes written.
* RMT: in SingleShotTxTransaction, improve error handling
I haven't seen any error here in practise, but it seems that this could
have locked up in the `while !is_threshold_set()` loop before in case of
an error or early stop code in the data.
* RMT: avoid one register access
* RMT: update HIL tests to use wrapping and extended RAM
* RMT: address review regarding data-writing loops
Make the code less startling by performing writes to the hardware in a
more imperative style via the for-loop; slightly refactor slice
splitting.
