2021-05-10audio_device: Fix build errorJerzy Kasenberg
ep_in_as_intf_num was incorrectly used to access out interface which is defined for 'in' interface. Code related to 'out' endpoint should use ep_out_as_intf_num instead.
2021-04-30Remove n from tu_fifo_get_write_info() and fix bug in vendor classReinhard Panhuber
2021-04-30Remove variable n in tu_fifo_get_read_info()Reinhard Panhuber
2021-04-30Change read infos to pointer typeReinhard Panhuber
2021-04-28temporarily fix include recusrive loophathach
2021-04-23Change tu_fifo_get_linear_write/read_info() to return a structReinhard Panhuber
Compilers always complain that variables set by function via pointer might be uninitialized so to avoid that return values are now delivered via struct.
2021-04-23Init len_wrap = 0 to fix compiler complains.Reinhard Panhuber
2021-04-23Implement functions to allow for DMA usage in audio driver.Reinhard Panhuber
- 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.

2021-04-03Generalize audio driver for 3 audio functions plus a lot more.Reinhard Panhuber
- 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)

2020-09-28audio_device: Update explicit feedback supportJerzy Kasenberg
Feedback can be specified by the user code and will be sent at feedback endpoint specified interval.
2020-09-28audio_device: Allow one FIFO for N channelsJerzy Kasenberg
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.
