2021-05-02some text fomarting, update unit test to test get buffer info for fifohathach
2021-04-30Remove n from tu_fifo_get_write_info() and fix bug in vendor classReinhard Panhuber
2021-04-30Comment cleanupReinhard Panhuber
2021-04-30Remove variable n in tu_fifo_get_read_info()Reinhard Panhuber
2021-04-30Remove all remainings with peek_atReinhard Panhuber
2021-04-30Remove offset feature from fifo.cReinhard Panhuber
2021-04-30Change read infos to pointer typeReinhard Panhuber
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.
2021-04-23Implement 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.

2021-04-07remove tu_fifo_backward_write/read_pointer APIhathach
since it is illegal from fifo perspective

2021-04-06refactor _ff_pull_n() with const addrhathach
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)

2021-03-23Fix bug in writing to constant src/dst address.Reinhard Panhuber
Copying has to be conduct in full words (at least for STM32). Renamed copy function to tu_fifo_write_n_const_addr_full_words()

2020-09-26Change modulo substitute to while ( idx >= depth) idx -= depth;Reinhard Panhuber
2020-09-25Fix wrong comments, rename pos to offset, rename overflow().Reinhard Panhuber
2020-09-23Fix bug in modulo substitute.Reinhard Panhuber
2020-09-23Change maximum depth to 2^15 which allows for a fast modulo substitute.Reinhard Panhuber
Thus, however, overflows are detectable only for one time FIFO depth.
