Spin Semiconductor

I need a pot to be able to sweep through values from -1.5 to 1, is this possible to do through some SOF commands? I cant seem to get it to work when I do that. any help would be appreciated! thanks

I'm assuming you have one leg of the switch connected to power, the other connected to the pot input. When you have the pot turned all the way down you are essentially connecting the pot input to ground, and when you hit the switch you are connecting power to the pot input which is connected to grou...

so if i tied all to ground would that select program 0?

is there a best practice when it comes to unused switch pins? should I tie them to ground via 10k resistor or to 3.3v? or does it make no difference (other than the program number)

I was wondering if this would be an ok configuration for using two spins - input buffer-->fv1A-->fv1B-->output buffer would you need any buffering between the chips or is that not necessary? also would i be able to drop the output resistor and capacitor of the first fv1 and the input resistor and ca...

to do an arbitrary number could you not do a mask then scale and offset it to your needs?

Great thanks. I'm not sure I notice much of a difference but it saves me a line of code so I'll take it. Thanks a lot frank

aha! got it! thanks a million frank

ok Ive got this and im still having the same problem. no sound with pot1 turned all the way down lldax ADCL rdax fbk,1 mulx pot1 wra delayl,0 cho rda,RMP0,REG|COMPC,delayl cho rda,RMP0,,delayl+1 wra temp,0 cho rda,RMP0,RPTR2|COMPC,delayl cho rda,RMP0,RPTR2,delayl+1 cho sof,RMP0,NA|COMPC,0 cho rda,RM...

thats what im trying but when I have the knob controlling the feedback also controls the effect level when I try that heres the relevant part of the code im working on ldax adcl rdax fbk,1 wra delayl,0 cho rda,RMP0,REG|COMPC,delayl cho rda,RMP0,,delayl+1 wra temp,0 cho rda,RMP0,RPTR2|COMPC,delayl ch...

trying to make a feedback loop - connect the input to the output. It can be done with hardware I know but I would like to do it with code. any idea? looking to have one of the pots control the level of feedback.

thanks!

excellent! thanks for the tips!

is there much risk in having the voltage go slightly above 3.3v? should i have to worry about resistor tolerance when calculating the voltage divider or is the chip able to handle that sort of inconsistency?

What would be the best way to use a sequencer's cv to control a pot input on the fv1? dont want to exceed 3.3v but the sequencer I have puts out 5v. Im worried that a voltage divider will not supply a constant 3.3v depending on the dc adapter the pedal is plugged into.
