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.

Hi Geoff

As done by matherp on STM32/L4 , is there a possibility to implement this functionality as well on PIC32MX170?
Maybe through CFuntion?

Thanks
Antonio

Can't be done as a CFunction - too big to load - tried and failed

just out of interest, how much flash space would it consume if it were possible to be added?

i for one would be happy to swap file system support (and double precision) for a loss of speed (ie, higher code optimization) and the moving of colour LCD support into custom functions.

of course, such a decision would be up to geoff.


cheers,
rob :-)

Around 6K flash + 1K RAM on the ARM, but ARM code seems more compact than PIC32Edited by matherp 2018-12-18

Now I'm confused.
I would have thought there would be plenty of room in the flash on a 170 for a 6k Cfunction. There's plenty of RAM too if it only needs 1k or so.

Can you elborate on this a little, as that seems doable with a 170 to me.
I have no doubt you are correct, I just would like to understand this a little more, as the figures don't seem to agree.
