Spin Semiconductor

the noise is only an issue when mix and volume are maxed, it’s fine at unity gain, and I think it’s just a mixture of the things frank mentioned, I’m leaning towards a bigger box and separate boards for my next project

I currently have the screen and micro controller on a breadboard, connected to a pcb with only the fv1 circuit, the noise is coming from the connections to the pots, it goes away if I disconnect them

I’m trying to read the fv1 pots using a microcontroller but I get noise into my audio signal, is there some way to isolate the noise, tried a choke, and resistors with no luck

Build docs:

pinMode(PB4, OUTPUT); //fv1 pin13
digitalWrite(PB4, LOW); //high ext, low int

after checking with a multimeter pin PB4 is still high
must be something wrong with the pin, it wouldn't be the first time
at least I know it is possible to do, thank you

I didn’t think I needed a pullup resistor because I’m sending either a definitive high or low to pin13

Is it possible to use a micro controller to set pin 13 high or low
To access the internal programs?
I’ve tried and it always uses the eeprom

works great now thank you

not working here either

I think it’s dead, I tried sending an email to the guy that deals with conformation and got this:

I never receive a confirmation email to get into that forum, where else can I download spincad?

Finally got this working with the lorlin 16 position switch, thanks for the tips!

My point of access is the 8 pin socket that holds the attiny, it’s connected to the fv1 but it’s upside down on the schematic, so pins 5 6 7 are connected to s0 s1 s2, but on the pcb it looks like pins 1 2 3

Update: I wasn’t even going into s0 s1 s2, worked perfectly when I figured that out

I’m afraid I just have to accept defeat with this one, thank you for the info and advice anyway

But it doesn’t work, that’s why I’m here!
