Re: Extra pot input in stereo operation?
Nope, only 3 POT inputs. You may need to give up stereo or switch to the FXCore with 6 POT inputs.

Re: REG flag in CHO Instructions
Correct, CHO RDAL just give the current value of the selected LFO so if you read it multiple times in a program you may or may not get the same value. All LFOs are updated once per sample period but at different times for each LFO and their associated SIN and COS registers.

Re: REG flag in CHO Instructions
Simple answer, never.
The value in the register will stay there until you do a new REG so if you want a "live" value then just do a REG.

Re: Reverse engineering the auto-wah
I think one of the things that throws people is the log subtraction simply because most people have not thought about log functions in all the years since they let school and forget that subtraction in log domain is division in linear domain. LOG and EXP are really powerful and useful so a short che...

Re: FV-1 not recognising EEPROM?
1. Post link to schematic.
2. Many times power on issues are related to the crystal. Try a larger cap on it.
3. What happens if it does the strange power on thing but you change programs? Does it read from the EEPROM or internal?

Re: Reverse engineering the auto-wah
Since Keith did not like to write documentation but we did discuss the operation of the filter control I'm going to take a shot at explaining this from what I recall of the conversation. I have added additional comments in the code as well as a high level view of what that block is doing. I do look ...

Re: SPINAsm and Empty programs
There is no official NOP so any instruction that does not change the values in ACC or other registers can be used as a NOP. When comparing the 0x00000011 to 0x11000000 it could be either a typo or one is in little endian and the other big endian. But ultimately as long as the instruction does not ch...

Re: Encoder
The Nidec one you linked to is 10 position, you want an 8 position of that type. The Panasonic one is the wrong type, you want absolute position and the Panasonic one is not. You can use a 24lc64 or 24lc128 just make sure to write to them starting at address 0. The upper areas of memory cannot be ac...

Re: WRLX and WLHX coeffient equations
Next up, I am looking at the envelope/peak detector code in the auto-wah. That is one seriously dense bit of code and I even remember being on vacation in the San Juan Islands years ago when I figured out why some of it was done the way it was. Will contribute that when I get done. Ah the fun of re...

Re: POTS VALUES
Recommend to use POTs of 50K or less, too high a value can current starve the POT ADC.

Re: WRLX and WLHX coeffient equations
The information in the knowledge base and the rest of the site is not intended to teach you DSP, it is for people that have a basic knowledge of DSP to learn how to implement audio specific structures in the FV-1. It is also expected that the reader will spend a little time working out the details t...
