Hi Admin
I think I found an error in the cheatsheet document:
http://www.spinsemi.com/knowledge_base/cheat.html
The RDFX instruction formula looks different in the manual and in the cheatsheet. Which one is the correct one?
Acc + (reg-acc)*k1
Vs
Reg + (acc-reg)*k1

Idea - Audio ADC as a digital input
So I have a pedal concept where a switch parameter (on/off parameter) for the FV-1 would be useful in addition to the 3 knob parameters. The hardware I have available includes an ATTINY microcontroller (basically a small arduino) that runs on the same supply voltage (3.3V) as the FV-1 chip. My idea ...

SpinASM Output Window not appearing [FIXED]
Hi I've been running SpinASM on a windows 10 computer for a few months and today the Output Windows has stopped appearing after I build projects (Project dialog). I've looked everywhere, but I can't figure out how to enable the Output Window. I've tried reinstalling SpinASM without any luck. Have ne...

Thank you Frank! I'm driving the LED directly with the output from DACR: DACR -> Resistor -> LED -> Ground I've read elsewhere on the forum of people using a LED driver solution where DACR connects to the gate of a NPN transistor that switches the LED on or off. Is there any reasons to not driver th...

Indicator LED connected to DAC
Hey So I'm writing a program where I use DACR to display a waveshape. Everything is working flawlessly but whenever DACR outputs a value close to 1 or -1 the clip LED lights up. Is this in any way harmful to the chip? I'm guessing "no", but I always get the vibe that when a clipping indica...

hey Have been thinking about this application myself. Why not just do away with the ramp oscillator and increment and reset addr_ptr position directly? Something like this: -Set address increment size (pot ctrl) -Increment read address -If read address is beyond delay buffer length (NEG or >32768) A...

Reviving an old thread! I wrote this code that gets you 500 ms of reverse delay. The delay time, or rather the size of each reversed segment can be adjuster with POT0. The program uses a counter to increment ADDR_PTR to read though the delay buffer at double the speed of the audio samples (creating ...

Program Length / Instruction Limit Question
The FV-1 is limited to preform 128 instructions per clock cycle. Can a program contain more than 128 instructions if it's structured in such a way that no more than 128 of the instructions are required each cycle? e.g. set X negative or positive with a pot if X is negative: perform 100 instruction p...
