Re: Pops when changing programs in a second eeprom

This changes the plan of attack. Do the following: Note which programs clicks happen between, i.e. click when going from 2 to 3 but not 3 to 2, etc. If this is consistent then issue is most likely with your code, you are introducing an offset somewhere in the code. If this is not consistent then pr...

Re: Pops when changing programs in a second eeprom

Frank I was wondering how the FV-1 reads the S0-S2 inputs when checking if they have changed. Does it poll them (if so how often) or does a change in any one of the inputs cause an interrupt which then tells the FV-1 to read in the three switch input? Also, having looked at the FV-1 Datasheet, I can...

Re: Pops when changing programs in a second eeprom

Hi Steve and Frank, As the firmware programmer for the project Steve has asked you about I can fill in some of the details of how I handle FV-1 program changes. Our pedal reads a 'user patch' from a separate eeprom. This contains the FV-1 program number and the pot settings for P0-P2. The program nu...

Ice9 has sent me a version from which he has removed the tremolo sections and that does assemble. I've compared the two side-by-side and I can't see any evidence that I've got two copies of Don's original code I've come across the locale settings issue with some of my own apps but I don't think it's...

I just installed SpinAsm on a different computer and tried it and it assembled fine. What is your computer setup? It's a Windows 10 OS with 16GB ram. All other SpinAsm programs I've tried assemble just fine. Ice9 tells me he's getting the same error as me after copying Don's code from the post abov...

I just tried it and it assembled fine. Not too many instructions (128 exactly), mem and equ statements are assembler directives not instructions. Hi Frank, I get an error log that says: <0000>[ Pass 1] [ 1015] Line: 250 "rdax   mono, 1       " - ERROR:Program Length Exceeds Limit - ...

Don, that was very nice of you to share your code. Sounds very good. I saw that in the code you put a question mark after "eigentone". These are the various frequencies that cause resonance in a system. Mechanical systems can have an infinite amount of resonant frequencies. In the spring ...

Re: IC EEPROM

Hello and thanks for the reply to ................................. I have a few questions: 1. Is your home (FV-1) is already 8 to program it according to what I asked PDF file? 2-for when we want more apps into the IC EEPROM programming how is that information in more than 16 states to call it thi...

Thanks slacker. I've been reading the specs of the Intel Hex files so now I understand the format. With limited memory left in the Nano's program space, I'm thinking it would be better to have the PC handle the donkey work of decoding the hex file and then sending it a byte at a time to the Nano whi...

Uploading Hex files to external EEPROM using an Arduino

Ice-nine and I are working on an FV-1 project at the moment in which we hope to have two external EEPROMs which have their address pins set so that they can be selected by an Arduino Uno. Hopefully this will allow to expand the FV-1 programs to 16. We have designed a 3.3V <-> 5V bidirectional logic ...

Start up Noise

The sound sample (see link below ) was taken from an SKRM module on power up. If I switch off and immediately back on again, there is NO noise but if I wait about 5 seconds and power up, the noise is there again. The clip LED also flashes briefly when there is NO noise but remains on longer when the...
