Re: Two FV1 sharing a common EEPROM?
If you are going to use a micro to control the clock, why not expand on the micro to also control the program changes, that way I think you could use one EEPROM for both FV-1's by introducing a delay into the program read of each FV-1.

Re: Microcontroller and FV1 in parallel
You will first need to make sure your microcontroller is a 3.3v device, if you use a 5v device like an Arduino Nano it is a 5v micro and will need to have 5v-3.3v level shifters. Easier to use a 3.3v Micro so no need for level shifters. Thanks for the reply! I'll use a microcontroller chip directly...

Re: 2 FV-1 ICs and number of EEPROMs
Right - the EEPROMs are not all that expensive, but in order to use more than 8 programs, I need to enable and disable every other EEPROM, which takes more digital pins on the Arduino to do so in the event of 4 EEPROMs versus 3 EEPROMs, thanks, BC Not really, If I understand your situation correctl...

Re: FV-1 not recognising EEPROM?
Just to add to what Frank has mentioned. If the internal programs work correctly with T0 at 3.3v but when T0 is switched to GND and you confirm T0 pin does in fact have the correct voltage when set to GND for EXT programs. I would check the EEPROM is working, which you say it does in another pedal t...

Re: Spring reverb
Hello everyone Theres a comment within the program that says reverb time could be added, i've commented this ; Chirp out in ACC - add dry, and output it ;mulx pot0 ; reverb level, use whatever pot is free So that reverb volume is maxed and freed pot1 to have a decay control, ive tried: ; Do reverb ...

Re: Clicking noise when changing certain programs (pot)
I spend more time in the DSP section of diystompboxes.com than I do over here, so to the extent that I'm going to support SpinCAD, that's the place to ask. Of course, SpinCAD just creates SpinASM, so you should be able to get some level of answers here by just posting your code here. I haven't even...

Re: Serial connection
Frank, thanks! Does anyone have any information on the first question? Have you tried connecting several FV-1s in series? Yes..You can connect FV-1 DSP's in series or parallel. For your purpose I would consider just 2 FV-1 chips as 2 of the effects can easily be programmed on 1 FV-1 and give enough...

Re: Timing for switching banks or patches
Hi Mark, from your description it sounds mode like you have a bypass switch pop noise when switching between effect and bypass rather than noise from effect changing (Sx). I would look at your bypass switching first to see if you have a problem there.

Re: FV-1 Pot Inputs - Using Digital Pot or DAC?
The best way is to connect the 3 pots to the uC analogue inputs then PWM the uC output to the FV-1, if you use a 5v uC you will need to make sure the PWM output is converted for 3.3v.
EDIT - I see Sweetalk has suggested the same above.

Re: Variable bit depth
I don't know if this will help you but it is a program published by 'Slacker' some time ago and it uses the pot SKP routine to select bit depth. It was shared public so I don't think Ian will mind me re posting posting it again. ;Digifuzzer ;Pot0 - Sample rate reduction ;Pot1 - Bit depth reduction a...

Re: Function of T1 pin?
Frank mentioned before that the T1 pin was used in production process and has no function for the end user IIRC.

Re: Experimental Noize - SKRM-C8-eTap2: For Piets echotapper
Hi Tom, Mick here, I have never had any schematics on the Stanley website as far as I can remember but I made available schematics of public FV-1 circuits on the Diystompbox forums a long time ago. There are some new schematics made available over there which have been posted by a few different memb...

Re: Some things I've learned about the FV-1
Hi alsag, You have described that you have noise until you touch your guitar strings, this would suggest that you might have a grounding/wiring problem with your guitar. This type of grounding problem may be apparent as buzz. Of course you may also have other issues but ditching development of the F...
