Suloo Posted November 9, 2014 Report Share Posted November 9, 2014 (edited) Hello, i`m new to DIY midi controlers, but am interested in building a box with 16 encoders and two buttons for paging the encoders to the next or previous 16 CC messages. Also i would like to have two additional buttons for other purposes. I want to use the CORE_STM32F4 Modulehttp://www.ucapps.de/mbhp_core_stm32f4.html and two of these DIN X4_ V2 moduleshttp://www.ucapps.de/mbhp_din.html What i now am wondering about is wether these encoders would be suitable for that build and if anyone has experience further readings or anything else related to these encoders. Any help or information would be great. Did anyone of you use them in a project?http://www.cliffuk.co.uk/products/encoders/index.htm many thanks!

TK. Posted November 9, 2014 Report Share Posted November 9, 2014 Hi Mark, the encoder spec (http://www.cliffuk.co.uk/products/encoders/EncoderSpec.pdf) looks fine, it will work :) Note that MIDIbox NG allows to connect up to 16 buttons to J10A/B, see also this configuration example: http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fmidibox_ng_v1%2Fcfg%2Ftests%2Fdiocfg_1.ngc This means that you only need a single MBHP_DINX4 module for 16 encoders, the two buttons can be connected to J10A.D0 and D1, and with "DIO port=J10A emu_din_sr=5" they will be available as BUTTON:33 and BUTTON:34 Best Regards, Thorsten.

Suloo Posted November 10, 2014 Author Report Share Posted November 10, 2014 (edited) Hi Thorsten, super, thx for your response. I still wonder because of LEDs. Since i would like to use the bi-colored once. Green/Blue, i would need two additional inputs for each encoder right? Plus the switch also got its own circuit i guess. So 3 additional inputs. This wont be possible with just one DIN X4 module right? Also i found this ones here: http://at.rs-online.com/web/c/?searchTerm=tyco+encoder They are the same i think, just another vendor but located in Austria, wich is good for me, since im located in germany. Here are the specs: http://docs-europe.electrocomponents.com/webdocs/0ccf/0900766b80ccf883.pdf Would these also work? What i also wonder is if i should use the ones with a flatted or knurled shaft. Any ideas? I don`t know wich one is for what. And if i would need the vertical ones or horizontal ones. cheers Edited November 10, 2014 by Suloo Quote Link to comment Share on other sites More sharing options...
novski Posted November 10, 2014 Report Share Posted November 10, 2014 Hi suloo I once made a pcb for RGB colored encoders. You can find the compleete dokumentation in the wikipages: http://www.midibox.org/dokuwiki/doku.php?id=fadercore_-_vlr-8enc Feel free to download the Eagle files an expand it to 16...

TK. Posted November 10, 2014 Report Share Posted November 10, 2014 Can't give you a better reference project than Novski :) Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Suloo Posted November 11, 2014 Author Report Share Posted November 11, 2014 Wow, nice one! That looks awesome. I also thought about a motorfader controler for the next project. hm :) Will check that one out for sure. Thx! Quote Link to comment Share on other sites More sharing options...
