Re: read protect eeprom
As Frank said, No. It is not possible to protect the code stored within the 24lcXX EEPROM but it is possible to protect your code if you wanted to do so. Sort of. You would need to use a microcontroller with internal EEPROM space to send the programs to the FV-1 in place of the normal 24lcXX EEPROM,...

Re: Stereo effects in general + overload delay ram
For Stereo Reverbs you could have a look at the reverbs in the 'Free DSP programs' section on the SpinSemi website, there are some stereo reverbs by 'Harmon Grold' to download and try. If this is the type of thing you are looking for you can use the code and optimise it to what you would prefer for ...

Re: Reconfiguring the FV1 1313A Reverb chip - Absolute noob needing help
No need to worry about the 1313A markings on the chip it is just the manufacture date code, made in 2013 so it's an older 7 year old IC. The Spin Software only connects to the Spin FV-1 Development board, if you have a pedal with the FV-1 in it you will need to use a programmer to send a .hex file (...

Re: Mid Reference Capacitor
it is just dataheet stuff, the main datasheet suggests 1uf for both but the dev board dataheet has 10uf it doesn't make much difference. I use 10uf in both positions.

Re: JAM
As far as I know the latest SinASM is 1.1.30.0 that may fix your compile issue.

Re: Program Selection Options
I am using a small 8 pin PIC12F615 for this, it still has 2 pins available which could be used for a bypass but one pin would be the switch and the other could control the bypass relay. It would be better to use a bigger PIC for LED and mute outputs if you wanted to have both bypass and program sele...

Re: Pops when changing programs in a second eeprom
FV-1 is a typical CMOS process so anything above 0.7*VDD is a "1" and below 0.3*VDD is a "0" Have you looked at all the signals for a glitch? Personally I would ignore everything else until I tracked down with a scope where the pop is originating. Is it on the power line? A glit...

Re: Program Selection Options
I use a small pic chip to output the 3 bit binary code needed to switch s0-2 the pic is directly connected to these pins but if you take this route you must use a micro that is 3.3v otherwise you may damage the FV-1. The 8 position switch is set up as a resistor divider which connects to the ADC of ...

Re: Pops when changing programs in a second eeprom
Hi, I'm also one of the members of this project, the Arduino is a NANO which uses the ATMega328p which is a 5v device but we have level shifters in place between all FV-1 pins. I can dig out the full schematics as requested if I am able to send PM.

Re: Spring reverb
Great reverb, good job! It’s a pity on one of the regulators that is responsible for the tremolo (vibration) you can hear how it works incorrectly, then an effect appears, then it disappears, I tried different values, but so far it didn’t work out, but it's temporary) It's worth it. Could you expla...

Re: Reading pots noise
I have just had a quick look at the schematic and the board and it looks to me that you have the pots connected to the FV-1 in the normal method and also connect the wiper to the micro, would it not be a better idea to read the pots into analogue inputs on the micro then send to a PWM output which d...
