03f974c9b9 Implement functions to allow for DMA usage in audio driver. 
- Add tud_audio_n_get_ep_out_ff(), tud_audio_n_get_ep_in_ff(),
tud_audio_n_get_rx_support_ff(), and tud_audio_n_get_tx_support_ff()
- Change get_linear_read/write_info() to return linear and wrapped part
at once
- Adjusted affected code in audio_device.c and tested with
audio_4_channel.

9b2ddd9cc6 Generalize audio driver for 3 audio functions plus a lot more. 
- Audio format and parameters are parsed from descriptors thus user no
longer needs to give them explicitely

- Tested for 4 channel software type I PCM encoding with 16 bit with 1
channel per FIFO and 2 channels per FIFO (this is I2S specific)

2ace98e943 audio_device: Update explicit feedback support 
Feedback can be specified by the user code and will be
sent at feedback endpoint specified interval.

759d530506 audio_device: Allow one FIFO for N channels 
This allow to build with single FIFO for devices with multiple channels.
Having just one FIFO greatly reduces time needed to feed endpoint.

This change also allows to have one FIFO with 24 bit samples that
is not rounded up to 32 bit elements.
CFG_TUD_AUDIO_RX_ITEMSIZE and CFG_TUD_AUDIO_TX_ITEMSIZE can be manually
defined. This allows to use FIFO more efficiently when 24 bits samples
are already using 3 bytes, in this case there is no need to put them
into FIFO one by one.
For 8, 16, 32 bits samples size efficient FIFO access is always used
when single FIFO is selected.

This also changes FIFO element size to 1, FIFO usage was confusing
in some place it treated content as byte base in other it looked like
ITEM size is to be used. Also bufsize that in most (maybe all) cases
was really meaning item count.
bufsize now mean buffer size in bytes so there is no confusion.

5ad2f8efc6 audio_device: Fix inline function specifiers 
Having just inline keyword for function specified in header
may not be enough to generate code for function.

Adding static solves this problem.
static inline is used in all other inline functions in TinyUSB.

338e96fa82 Remove tud_audio_n_write_ep_in_buffer() as long as ISO EPs are not RBs. 2020-09-03 18:09:46 +02:00
Reinhard Panhuber
8f0693346c Allow epin_buf to be written directly into in case no TX FIFOs are used. 
This is helpful if you have already encoded audio data and want an
efficient way to send it. However, this approach is NOT THREADSAFE so
far and works realiably ONLY IF tud_audio_n_write_ep_in_buffer() is NOT
called form an interrupt!

b1f0d6f57e audio_device: Change CFG_TUD_AUDIO_TX_BUFSIZE to CFG_TUD_AUDIO_TX_FIFO_SIZE

condition while in other places CFG_TUD_AUDIO_TX_FIFO_SIZE is used.
