Rotary Encoder on MF
Rotary Encoder on MF Posted on: 23.02.2011 by Neva Hoppenrath three questions1. will these Panasonic EVQ-WTEF2515B Mechanical Rotary Encoders work with the midi-fighter? 2. will the encoder and the switch work 3. if they do work is it posable to use 16 of them? because i want to make a midi-fighter with all of these instead of buttons here are the details: The EVQ-WTEF2515B rotary encoder by Panasonic features a shaft rotation angle: 360 | |

| Neva Hoppenrath 24.02.2011 | in your opinion what would be the best DIY midi board for me to use. Here is pretty much what i am looking to do: - i am looking to control all 4 effect banks in traktor (but still be flexible so i can use it with ableton in the future) - have 16 endless rotary encoders that are also buttons - have some LED feedback (like the brightness of the LED relates to the amount of the knob) from the software (traktor & live) - have it fit into a midi-fighter sized case (ideally the actual midi-fighter case) really in not so many words i am look to put a Faderfox FX3 in a midi-fighter, kinda? so i read the diy midi kits review on the blog and the livid brain looks like a good choice... you believe? thanks everybody for all of your input on this, RPK |
| Adolf Hit 25.02.2011 | If you want to add that many device you are probably best off just building a separate custom controller based on a DIY midi board which has native support for the encoders, unless you really want to take the hard road. If this is the case for 16 encoders I would use another micro controller to take care of decoding the encoders and then use some kind of coms protocol between the midifighter and the expansion micro. |
| Lisa Lochotzki 24.02.2011 | Rotary encoder is somehow tricky to work with. You need to poll them really often (or use interrupt-on-change) compare their actual position to their previous one. If different, and after a Xor bitwise operation, you know if you send an Inc or Dec command. I don't see how a Multiplexer could help here. What I see is OR another Microcontroller OR use an I/O expander with Interrupt line such as MCP23017, MCP23S17, MCP23018, MCP23S18 with 'maybe' some D-Type-Flip-Flop to simplify the code. HTH |
| Neva Hoppenrath 24.02.2011 | thanks Fatlimey, i can program a little in flash, so i believe i will take a stab at it. now on to the wiring of it, to run 16 of these encoders with the 16 switches would i need to do something like your "Multiplexing 8 analog inputs using a CD4051B" post? Because that is a little over my head, i believe. |
| robert chanda 23.02.2011 | So you know your HTML, bu can you program Flash? If you can, you're closer than you may believe as you already know how to use a compiler. Setting up the code to build your own version is not hard, it just neds some background knowledge in:
All of these things are covered in innumerable "beginning programming in C" tutorials so dig one out and follow it through. |
| Neva Hoppenrath 23.02.2011 | thanks midifidler, do i need to modify the code because i want to use 16 of them or just because they're rotary encoders? That word code is a little scary to me. Here is the extent of my Midi-fighter coding knowledge: I had two MF's go crazy and give me the "upper-left light of death" and every time i tried to update the firmware, to fix them, i could never get them to work again. I was using terminal and my computer is a mac. When i sent them back to the guys at DJTT they got them to work right away. that said i am somewhat tech savvy (insert air-quotes here). By trade i am a graphic designer and have a good grasp of HTML, CSS, and action-script. I also have made custom arcade sticks by hacking old PS controllers. is this something I am capable of doing myself? |
| Adolf Hit 23.02.2011 | Heya, Yes they will work, however you are going to have to modify the code to make that happen. |
