FxCore is great

Hi gents

This fxcore part is great. I'm having a nice time with it. I'm porting some of my fv1 reverbs to the fxcore dev board and it just sounds so much better. The asm is a little more complicated, but the instruction set is way more powerful. I'm going to need to up my game to use up all these cycles.

I wish someone was working on a board for this!

There is, Matthew Farrow of Disaster Area Designs/Alexander Pedals and I have been working towards an open source PCB/pedal design/assembler, the Sandbox FXCore. Assembler is done and online https://fxcore.sandboxpedal.com/ , Matthew released the first pass of the PCBs and he should have them back soon for testing. Basically the same idea as he did for the FV-1 Sandbox pedal, assembler at https://fv1.sandboxpedal.com/ and the PCB files are in github at https://github.com/DisasterAreaDesigns/Sandbox-FV1.

FXCore PCBs will be released to github once they are proven. If using a chromium based browser (i.e. Google Chrome) you can assemble and write to the boards directly (EEPROM on FV-1, internal flash on FXCore), I've even done it as a test to an FXCore dev board from my Pixel cell phone using chrome.
 
Hi, are there any PCBs and Gerber files for the FXCore project? I believe there are open-source, shared files available, but I haven't been able to find them.

Hello Have the PCB files been released?

As I said, once they are proven. First pass is just arriving this week so need to build and test, watch the github link as they will be posted there when ready. Web based assembler is done and posted and should work with the existing dev board via WebHID (use Chrome or Edge browser), the firmware for the RP2040-zero board is done so just need to test/complete the boards.
 
Forgot to mention that the official tool set (assembler/preproc/GooeyCore) will support the Sandbox pedal so you can use any tool (web or computer based) with both the dev board and the Sandbox pedal. This updated tool set will be released when the PCBs are released.

You're amazing, Frank, I have great respect for you and your team. I think Fxcore will be exactly the same as Fv-1 in every aspect, meaning it will be able to read all the effect files that Fv-1 projects can read, right? Also, I hope there will be a video introducing the programs and how to load effects in Fxcore, because that's what everyone is waiting for. Best regards, Frank.

FXCore has been in production for several years and as far as I know it has no compatibility at all with Spin FV-1 source code. I would have liked that as well, but they had other things in mind.

As Digital Larry mentioned, the FXCore is already available but it is not source code compatible with FV-1. FXCore uses a different processing structure, etc. so making it source compatible would have limited the chip. But it has all the functions to replicate the instructions of an FV-1 it just may take 2 to do it. For example SOF in FV-1 is (ACC*C)+D which does not exist in FXCore but we offer multiplication and addition so you can build the equivalent instruction with 2 instructions and have extra features as SOF in FV_1 uses 2 fixed values while there are multiplication and addition instructions in FXCore that allow you to use registers (MULTRR and ADDS) so you can change C and D within the code. Or to just make a working SOF equivalent use MULTRI and ADDSI. Really it gives the programmer more choice, adding extra instructions just to be source compatible would have limited the chip or made it more complex. If someone really wanted to they could try to write an FV-1 to FXCore source translator, things like LFOs and SKP might be a pain but but other things should be straight forward or easy like SOF to MULTRI/ADDSI pair.
 
Necro thread started by me 3 years ago.

I think the sandbox pedal idea is great. Hope this community gets a lot of use out of that. I did end up making my own board for the fxcore a few years ago but that product didn’t work out.
