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.
Missing comment
Correct adc silence threshold for 1x/2x. Correct ADC BITLEN for CIC_STAGES*log2(OVERSAMPLE_RATE)
This is not the right fix. Investing then will commit the right fix.
Horrible screeching on *2, I think down to this
Added another file needed to build
Add some unused stuff to the qsf
Prepare for 1.29 release
Added volume for SIO DATA and ADC
Only reset serial port on initmode (thanks for detailed bug report to phaeron). This needs testing against real pokey on the harness when I get time, but applying the simple implementation for now.
Flip sign for spdif. When adc silenced revert back to mixing sio data a bit.
Increase ADC volume. Try to decrease ADC noise by digital methods: FIR filter of problematic frequencies, silence ADC when nothing playing. Disable ADC for models that do not fit these features (M02/M08 with sample memory)
Fix for 10M16 flash
Do not overlock keyboard io expander so much!
