Spin Semiconductor

1. Patches are going one after another in spin asm project. So, if you have no empty slots in project, you will have no empty patches in hex file.
2. fully empty patch contain {0x11 , 0 ,0 , 0} x128 times .
3. Not programmed area on the flash chip usually contains all 0xFF

atmel mcu have hardware pwm, but afair it's unused in arduino.
If you write own software on C , then you can use hardware pwm.

For now you can provide additional LPF on FV-1 side like : ldax Pot2 : rdfx pot2f , 0.002 : wrax pot2f , 1

Of course, square waves are wide specter, so, use low pass filter (at least RC chain of 10K resistor and 100n cap) maximum closer to arduino
And don't forget divider +5V of arduino into 3.3V of FV-1

"it safe to assume any patch starting with 0x80" - never assume this patch can start with any of commands+data. Use address offset. Patch#0 = offset 0 , Patch#1 = 0x200 , Patch#n = n*0x200 if You need compression - use popular compressors, or kind of RLE. I did kind frequency compressor (F...

Ramp LFO (DDS) is only several lines of code, then it can be mirrored to triangle, then you can use servo technique to move pointer

my ali experience was bad, chip were D-category , noisy , with lot of problems in sound.

order several thousands FV-1 with your custom internal programs, as electro-harmonix did

no flags is testing, but it working?
Great idea, thank you!

ADC could work with square waves, 20Hz and higher (you will get harmonics on input), I tested it. Square waves is ticking and clicking in audio path, because adcr & adcl pins are close to each other and square waves are rich with higher order harmonics. So you can generate sine internally via FV...

Square wave is bad idea. You will get interference on high volumes. So, make RC filter as closer to MCU as it possible. Better to use internal Sin LFO (up to 20 Hz), or do your own sine LFO , somthing like that (was previously in forum and battling LFOs patch): skp run , start SOF 0 , 0.5 ;setup LFO...

much more, than 8. Because inactive ROMs can be on same inactive address.


32lc64 and others working fine, because have same protocol (2 bytes addressing)

ok, after PM I am showing cuted off reverse part of pdx delay , as is fade envelope is not too perfect, but it was no room for more accurate one, because patch was complex.

I did, but for commertial product . declicker diagramm you can see on the photo above.

Oh, i do simple analysis like "wrax temp, 0 : skp zro , label" , but thought skp has more common way to make unconditional jump.

Thank you
