Turn audio detect back on for v4.5 - silence is golden! Turn on sio data volume too. ADC at 1x is fine though (tested with 150V pk-pk from, iphone into SIO port). Correction of hex data.
Preparing for next release
Disable lowpass again, remembered the filter is explicit for spdif output (where it matters). Make spdif component explicitly have a port for left/right. Get all versions building again (some needed old dac for space reasons). Change default volume for adc and sio mixing for v4.5 (SHOULD not need the filtering there, testing now).
Allow fir and audio filter to be disabled by generics
Default lowpass to on again, think it was off by error
Added two new components: sync reset and 2nd order dither.
Use the same L/R mapping as v4. Added two new components: sync reset and 2nd order dither.
Switch on synchronous reset. Switch to dithering 2nd order sigma delta.
Just bash shebang
Synchronous reset to help with not starting sometimes
Added dithering with AIs help to reduce idle tones
Added pins for pokeymax 4.51 (tested on manually patched 4.5)
Added important note that this is broken
Disable dump transistors in fast pot scan mode. When counter is E4 reset allpot_next (it was overwritten because pot_reset_reg is 0).
Update readme with note about regulator change. i.e. should not work but not yet tested
Change regulator to a linear one that works with the io pin protection scheme
Added notes on status
Added warning
After testing 4b first run, there are a few issues. Updated to 4b2 with: Corrected L/R output. ADC bias improvement. ADC preamp out/in- corrected. Moved silkscreen name!
Added some untested kicad designs for pokeymax v4b, pokeymax v4.5, pokeymin v1 and anticmax v1
spdif seems to have left/right backwards
Incorrect clock for sio data mixing
Added audio signal detector
Break out audio detector to own module and improve. Now with zero crossing support.
