If you make the value of smooth in this line larger you will get less pitch bending try different values up to 1. equ smooth 0.001 ;Smoothing coefficient, adjust to change speed/zippernoise or just delete these lines rdfx ping_addr, smooth ; Smooth it : (target - current) * C + current rdfx pong_add...

Here's a very simple one, that will work with either a PC serial port or a USB to serial converter.

Yeah just an emitter follower, I stick a 100k resistor between the FV-1 output and the base of the transistor but may not be needed. Something like this example, pretty much any NPN will work, adjust resistor value to taste. https://www.mixdown.ca/redmine/attachments/download/129/emitter_follower.gif

If you just want to display the program number you don't need a micro controller. There are 7 segment display controller chips you could use. Have a look at this for some examples. http://www.electronics-tutorials.ws/combination/comb_6.html You would just connect the inputs of the chip to the S0, S1...

I've done this be putting 2 resistors in series between the wiper of the pot and the pot input on the FV-1. One side of the momentary switch then goes to the junction of the two resistors and the other side to 3.3 Volts. This stops the switch shorting out the pot but doesn't affect normal operation....

Like Frank says it looks like it's reading something in the file as code that it shouldn't be. I had similar problems trying to run spinAsm using Wine in Linux, unfortunately I never got to the bottom of it. Any chance you could post a copy of your spn file so someone can download it and see if it w...

I ran your hex file through Igor's online disassembler and the first difference in your hex file seems to be why pot1 isn't doing anything. The last line of this bit of code from the spn file multiplies the value from pot1 by 0.001. rdax pot1, 1.0 ;read pot1 mulx pot1 ;square value, range = 0 to 1 s...

Have you compared how it works to the built in flanger program (program 1) it should be the same as far as i know. I don't know if this is the cause of the problem but the hex file you posted has two lines that are different to the hex file I get if I build the rom_fla_rev.spn code. The top row in e...

There's some useful examples of manipulating pot inputs, including nice graphs to help visualise whats going on in the knowledge base.

Thank you :) I am curious how to go about this, if anyone has tried or knows of some info on how I would send the data from the micro controller or how the eeprom of the fv1 gets its address read. I would assume I need to use a few digital pins of the micro i2c and find a way to have it emulate an ...
