6e0acd7cd4 WM8904: Don't use MSEC2TICK in timeout calculation 2014-08-08 11:02:45 -06:00
Gregory Nutt
c9661ad5a7 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors 2014-08-07 18:00:38 -06:00

8065ab73a4 WM8904: Add reset logic to put the part back in its initial state after playing each WAV file. Base samles per second on frame length, not bits-per-sample. Use a different frame length for 8-bit and 16-bit data 2014-08-04 19:26:43 -06:00

dc8b040573 WM8904: Correct calculation of bitrate (I am not sure why this is correct). LR clock divisor is now a constant 32-bits per frame. Conditioned out interrupt logic; it is not being used. Also added some FLL lock interrupt/poll logic (which was subsequently disabled). 2014-08-04 15:08:20 -06:00

678c0aac8d WM8904: Tried disabling the SYSCLK while updating the FLL. Didn't help but is still probably a correct change 2014-08-03 18:44:51 -06:00

72b739fbcb WM8904: Add logic to analyze BCLK setup 2014-08-03 17:11:38 -06:00

b9384ced60 WM8904: Various updates to get BCLK/LRCLK correct. Acutally worse the parent, but I think is on the right track 2014-08-03 13:28:20 -06:00

3e1e15b04a WM8904: Can't reset the WM8904 unless we also reinitiailize all registers. Try to get a saner timeout based on sample rate, bits-per-sample, and buffer size. 2014-07-31 19:14:41 -06:00

e214382264 Audio: Change how the end of the audio stream is detected by the leaf audio component. This used by be done by looking for the first partial buffer. That does not work with the in-place sub-sampling performed by the PCM decoder: That always reduces the size of the buffer so that all buffers only partially filled by the time they get to the leaf. Now, a flag is set in the audio buffer flags set to indicate the final buffer in the stream. 2014-07-31 16:36:09 -06:00

d7a9633dcd Rename pcm_decode.h to pcm.h since it will hold more than just decoding definitions. Fix some porting errors like idbg should auddbg, etc. Add wav file header and a few low-level wav utilities. 2014-07-22 15:54:56 -06:00
