No. The FV-1 is a Spin chip and the FXCore is an EN chip. Chips are targeted at slightly different market segments, the FV-1 is a great, all-in-one chip for basic effects and is in full production. FXCore is being designed to address some areas that FV-1 cannot do (higher resolution math, more POT ...

COMPARE PREVIOUS VALUE
Hi, i'm wondering how to code an if fuction. Let's say If the value of a pot is different than its previous value then go to an specific part of the routine.
I tried using the SKP function but it has no such condition (if ACC is not equal as PACC).

AM MODULATION
Hi, is there any way to use the LFO with a higher frequency than 30HZ without changing the crystal. Im working on a tremolo algorythm and i want to do some AM sounds. Thanks!

You will need to ask Piet over at echoTapper, he made the filters as part of the overall emulation of tape based delay. Frank, besides the emulation effect, my question is: if i'm going to feed my effect with a guitar (Bw from 80hz to 10khz) is it a good practice to restrict the BW of the input and...

Input and output filtering
Hi! I see on this schematic that the input and the output are filtered by two second order opamp filters. Is it necessary to use them on a guitar pedal design? Is SNR improved with this method?

Input muting
Hi! Is there any way to mute the input of the FV1? I tried to connect one leg of the input capacitor to ground but it cause noise at the ouput of the chip.

OUTPUT FILTERS
Hi! I'm running this simple program: rdax adcr,1 wrax wrax dacr,0 Circuit is: Input Buffer=>FV1=>Output buffer Im feeding the input with a sinewave 1vpp, and at the output of the FV1 the signal is slightly weaker (10% or 15% less tan the input). Is this normal? I've noticed that the datasheet sugges...

INPUT RESISTOR
Hi! I would like to know if it's possible to increase the input resistor (1k) to avoid input clipping from hot guitar pickups. Let's say 2k2.
Thanks.
Thanks.

The sof will not work in this case, also you cannot pass sof the address of a register. Try an RDAX. Ok so i tried this, but led is always off. I assume that mi increment is rounded to zero again: equ counter reg1 equ increment 0.00001 ;this coefficient turns the led on in 2 secs.) rdax counter,1 r...

sof only accepts a S.10 bit value for the adder so 1/327680 is getting rounded to 0. You will want to clear the acc then OR the value into it since you will need 19 magnitude bits to represent 1/327680 then add the current count value. Frank, i tried your suggestion but Asm says: <0000>[ Pass 2] [ ...

Just increment a register every time through the code and when it hits the value you want do what you need. Since it will increment every sample period the time it takes will be (1/samplerate)* count seconds. Frank, this is my code for turning a led to its full bright in 10 seconds. Dacl it is atta...
