Hi! i would like to know how to make a counter that finish counting at 1, and takes X seconds to get there.

Thanks!

You could use the switch code from my tap tempo program http://www.spinsemi.com/forum/viewtopic.php?t=302&start=45 If you make the "count" parameter much smaller, you will have to hold the switch down for longer before it changes. The "latch" register in that code changes be...

Thank you Slacker, i've tried it but i does not work. Led is always on. I'm trying to understand the code but im lost. I don't think there is an easy way to use the sine. It should be possible to replace the ramp with a counter something like this. equ ledramp reg11; put this at the top of the code ...

Hi! Is there a way to use a Sin for controlling the led rate indicator instead of a ramp? The thins is that i need that ramp for another line in the program. Thanks! ;Taptempo rate indicator, creates a square wave at the tap tempo rate sof 0,0.064 wrax rmp1_rate,0 ;set rmp1 rate to 1Hz cho rdal,rmp1...

Hi, i would like to know if this issue was solved. I have my circuit working for 2-3 minutes, then a strong white noise appears. I replaced the chip with another one and stills the same.

If someone is having the same issue, i had DC in the pot taper. Putting a capacitor solved the problem.

They should be identical. The ROM programs were made with an old, never released version of the assembler and a few of the mnemonics were different. I updated the code for the website to work with the released assembler so it is possible I made an error in updating the code. I will try to take a lo...

Regarding this limiter code, is there any way to make the threshold variable with a pot? equ sigin reg0 equ avg reg1 rdax adcl,0.5 rdax adcr,0.5 wrax sigin,1 mulx sigin ;square rdfx avg,0.001 wrax avg,1 ;average log 0.5,0 ;[square exp 1,0 ;root] log -1,-0.125 ;[1/X, set thresh @2 bits (2/16ths) exp ...

Hi! When i run the fv-1 internal program rom_pt_echo from the fv1 internal memory, i don't hear any zipper noise from the pot.
But when i load it into an external eeprom, it makes a much louder noise. Is there any reason for this to happen?

Hi, i would like to know how can i reach lower delay times in this example. If i lower the minimun time with SOF 0.997,0.03 (1s to 30ms) i does not work well.

Hi folks, is it possible to access pot 1 and pot2 alternative parameters by pressing a momentary switch for more than 3 sec on pot0 input? Any ideas on how to start with some code? Bye bye!

Hi! I having some scratching noise when adjusting the mix control from this typical application circuit. Pot works fine outside the circuit.

I'd agree with Sweetalk. On the FV-1 based pedals I've built I use buffered bypass with the input of the FV-1 permanently connected to the output of the input buffer. This way its always processing so when engaged there's no delay in hearing the effect. Buffered bypass also allows you to do "t...

Hi! i'm working on a FV1 pedal, and trying to find out the best way to bypass the effect signal. I've used the opamp configuration showed in page 3: http://www.experimentalnoize.com/wp-content/uploads/2013/04/SKRM-C8-R02.pdf What i do to bypass is to put a simple toggle switch between the TO MOD and...
