More than 64 encoders, and some buttons, too?

[Adam Schabtach]

I'd like to ask some advice for connecting more than 64 encoders to an STM32-based core. I'm wondering whether a matrix-scanning approach will not work with encoders, since perhaps contact-change events could be lost during the scanning process. I also need some digital inputs for pushbuttons, including the 64 integral pushbuttons. Those could be handled by a matrix-scanning technique, of course. I'm mostly wondering about the simplest approach for integration with the existing MIOS32 code.

Thanks in advance for any suggestions, advice, etc. If this has been discussed previously feel free to give me a link and say, "read this!" While I am new to the MIDIbox community I would humbly say that I have intermediate to advanced skills relevant to this discussion: I have already created my own clone of the STM32-based core (i.e. custom PCB, MIOS flashed into off-the-shelf STM32, etc.) and I have many years of experience developing music-related software.

Thanks--
