Axoloti software with Nucleo F411RE board

#1

Hi, I'm quite new to DIY synth, and the maker world, and I'm wondering if I will be able to use Axoloti software with a Nucleo F411RE development board which has the STM32F4 microcontroller.

I've just ordered the Nucleo with the hopes of making a dedicated, stand-alone, midi controlled synth. I would very much like to have the patching capability of the Axoloti software.

The board does not have midi input hardware, so I am guessing I would have to try building the circuit using the same configuration as the Axoloti (from schematics). Hopefully I can manage to figure that out without too much trouble.

Would it run natively with this board, or would there be a lot of work porting the code (which would be beyond my current capabilities).

Any help or advice would be greatly appreciated,
Andre

Expect a lot of work to port the code, the F411 has less than half the amount of SRAM compared to the F427, you'd need to strip a lot of functionality, reorganize the memory map, rewrite audio codec code. And it has around half the clock speed...

Hi Johannes, thank you very much for the quick and clear response.

Given the that most of the issues you mention are due to the lower capability of the F411, would it be feasible using a board with the F429 instead?

How much experience do you have, and how much time do you intend to invest in the port?

And what's wrong with Axoloti Core? I believe it would fit your application nicely...

I agree, the Axoloti would be great, but my goal is to learn more about circuit building and coding along the way. I am looking for manageable challenges, as opposed to instant outcomes. Currently I would describe myself as novice: I understand the principles, but have limited experience implementing them.

At some point I will likely get an Axoloti Core to play with, but for now I think I will improve my skills with other builds (Goom, etc.) and then come back to this idea with a better understanding of the work involved.

Thanks again for your input.
