rodneon Posted January 9, 2005 Report Share Posted January 9, 2005 First off, I'm new to this project and I think it's amazing! I can't wait to build my own MIDIbox.I was wondering if it's possible (and feasible) to build a MIDIbox and a 2-input merger using the same core module. Also, can the DIN module be used for MIDI input or is it only designed for buttons, rotary encoders, etc? Quote Link to comment Share on other sites More sharing options...
Duggle Posted January 9, 2005 Report Share Posted January 9, 2005 Hi,Midi-in generally requires a hardware UART. Unfortunately the Core has only one. The exception to this is the Midimerger application which uses all its CPU power to implement a second UART. The answer (not eligant but works) is to integrate a second Core board into your Midibox, configured as a dedicated merger.cheers Quote Link to comment Share on other sites More sharing options...
AndrewMartens Posted January 9, 2005 Report Share Posted January 9, 2005 It might be possible to use an I2C or SPI UART for the second merge port, instead of just bit-banging one of the digital IO lines as in the original merger design. A MAX3100 (iirc) chip would be useful for this.However, that would require a lot of tinkering with MIOS to make it work. Quote Link to comment Share on other sites More sharing options...
rodneon Posted January 10, 2005 Author Report Share Posted January 10, 2005 I figured it might be possible but would require a lot of reprogramming of the MIOS... I was just curious. It's not that expensive to build the merger anyway, so I might just implement a merger along with my MIDIbox project.Thanks for the replies.
