I’m planning to build a controller to control Ma-Lighting GrandMa OnPc software. Therefore I need 32 pot inputs and 160 button inputs. As far as I can see, that isn’t possible with one standard core-module. But will it be possible on a Core_STM32? How many DIN modules can be handled by the STM32 core?
Is it worth waiting a few months or does it take a while before the STM32 core is ready?
32 pots and 160 buttons is well possible with a pic based cored. Search for “matrix” 
Chaining up to 16 DIN SRs is a physical, and not a software limitation.

However, beside of the possibility to use a button matrix with the old PIC based solution (1024 buttons or even more buttons? no problem) with MIOS32 it’s much easier to scan a second DIN chain with less programming effort because of the flexible framework (e.g. generic SPI access functions) and C as a programming language instead of cryptic assembly code. It’s definitely worth to wait for the public release (some people are already using the MBHP_CORE_STM32 module)

Oke, thanks! I think when I’am ready soldering al those buttons, etc., the public release of the STM32 module will be done I’m not very experiensed with programming en soldering, YET
