Re: Eeprom switch bck1001
But it doesn’t work, that’s why I’m here! In that case, I would suggest you wire the encoded up on breadboard using LED's on the output and note down the truth table when each LED illuminates, check that the encoder is actually working correctly as per the data sheet. If the encoder is working corr...

Re: Eeprom switch bck1001
It’s a 16 position rotary switch not 8, and I don’t think I can connect it where the mode pot is, it has 5 lugs A B C D E and the mode pot only has 3 Ok, that is not a switch as such,it is a 4 bit grey code binary encoder. Take a look at the SpinSemi docs for similar configs, you will be able to re...

Re: Eeprom switch bck1001
http://www.pedalpcb.com/docs/Octagon.pdf This is the schematic of the circuit I’m trying to add the rotary switch to, after removing the attiny85 nothing else seems to be connected to s0 s1 s2 but the mode pot still affects the rotary switch somehow, mode pot needs to be fully ccw to get the above ...

Re: Eeprom switch bck1001
I see that you are swapping between EEproms by switching power to pin pin1, the best way is to change state of one of the address line pins. that may work better.

Re: write internal programs
order several thousands FV-1 with your custom internal programs, as electro-harmonix did Yeah, as igorp said, have your programs burned into die of the FV-1 which would mean ordering a lot of them. The other optoion if all you are worried about is your IP not being copied by others just reading the...

Re: can you 4 eeprom
You cannot use a 24LC256, you must use a 24LC32A Frank, I have used other EEPROMS like a 24lc64 and a 24lc256 without any problems as long as you start each program at the correct address for the FV-1, of course you can still only address 8 effects directly this way using S0-S2. Using a larger EEPR...

Re: can you 4 eeprom
Yes you can you up to 8 EEPROMS if done correctly, Each EEPROM has 3 addres lines which are used to select the active chip so you will need to make a switching circuit around the A0, A1 and A3 which are pin 1,2,3 on a DIP 24lc32a. Switching the active chip can be done many ways from a simple switch ...

You can delete these references as well: equ lp1 reg1 equ lp2 reg2 wrax lp1,0 wrax lp2,0 lp1 and lp2 are never used beyond being cleared to zero at init time. Call me crazy but I generally skip clearing my filter registers at init time. I suppose it might cause a pop under some circumstances but I ...

Thanks, Ice-9, I'm looking for an approach that will work whether the input is 5V or 3.3V. Would the level shifters do that? Hard to say really if that would work reliably, but it would be quick enough to test out on breadboard. you would need to use two level shifters, one for SDA and one for SCL,...

Symptom Clip LED always on I have found that this is usually down to two things. 1. The oscillator is not working, this will always produce a constant clip LED on. Try some flux solvent to make sure everything is clean. 2. if the FV-1 is set to ext. EEPROM an the EEPROM is empty or not fully making ...

I asked you for help because I do not have much information about the codes and i need And I need those codes All the info you need to learn how to edit the codes is in this document along with some other documents on the main Spin Website. http://spinsemi.com/Products/datasheets/spn1001-dev/SPINAs...
