Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Forum Index : Microcontroller and PC projects : FAQ / overview of CSUBs on CMM2?

Hi all,

Does such a thing exist? I'd love to have a crack at writing some CSUBs but don't know where to start. I'm a not-very-experienced programmer, but I have written (and successfully compiled!) simple c / c++ programs in Visual c++ on windows.

It's just what happens between the c/c++ code and the Cortex-M7 hex string that appears in a CMM2 basic program that's stumped me.

Any tips gratefully received!

Thanks in advance

John

Hi John,

I don't think there has ever been much beyond posts on the forum, try this Google search "site:https://www.thebackshed.com/ csub".

In a bout of enthusiasm last year I captured some useful links here:

https://github.com/thwill1000/cmm2-sptools/wiki

but life is too short for me to keep it up to date.

Best wishes,

Tom

This refers to the ArmmiteF4 but summaries a few things from the original CMM2 thread.

Hi John,
CircuitGizmos had 4 excellent modules on understanding CFunctions, circuitgizmos.com/projects/ . These are a good start.
In just re-checking the link for some reason I get an error when trying to select the module links, not sure what the issue is.

Many thanks all, I'll digest this lot and hopefully make some progress!

John
