Hid Usb Products Posted on: 13.03.2009 by Lisandra Cassanova Hey, i'm kinda new to this....i've got a controller design i'm working on that has 50 potentiometers (8 sliders and a bunch of pots).The USD HID interface i've found is the U-HID http://www.u-hid.com/index.php?optio...tpage&Itemid=1 Except the U-HID will only allow 16 potentiometers, so does anyone know of any other solution that are cheaper and have more inputs? Any ideas? Thanks in advance | |

| Latia Pfleider 19.03.2009 | hey guys, hi scrambled. I am using the u-hid on a controller that im still working on. I bought it before I knew that it was limited to 8 analog. It is limited because the device shows up as a windows gamepad/joystick and windows limits to 8 axis (analog). There is also the u-hid nano that has 8 pins so you could get 6 from those (6 pins + power + ground) I still like the u-hid because it should work well with the program I want to use to convert from windows hid to midi. I am going to use glovepie. Im also looking for something cheap that will get me a few more pots. If I stay with hid then the windows gamepad is going to limit me to 8 per board no matter if its the u-hid or not, and if I go with a midi hardware I will need to know more about midi signals. I read the umc32 manual and it seems like doing analog ports should not be very hard with it. So far on my device I have 5 slide pots wired and I am working on some lights and waiting until I can afford some rotary encoders for my jog wheels. Also the u-hid is very easy to config. |

| ezequiel tapia 18.03.2009 | looks like the arduino options are shaping up, the (yet to be released) arduino mega appears to have 53 points of IO - via via via |
| Lisandra Cassanova 17.03.2009 | thanks for the link, their alot more expensive than arduino but lucky i'm a good programmer. thanks alot for the help |
| Joesph Vincze 15.03.2009 | Arduino is nice, but if you don't know basic programming skills it can be frustrating. Look at the HALE http://www.halemicro.com It only has 32 inputs, but you can use two devices yo reach your 50. |
| Lisandra Cassanova 13.03.2009 | cool, thanks for the push in the right direction. i'll do some research and you know how i get on, thanks again! |
| ezequiel tapia 13.03.2009 | first, i'd recommend that you go arduino rather than U-HID if only because arduino has a very active and supportive community and improvements to hardware, shields, the IDE and libraries are being made constantly. even with the arduino you have a limited amount of analogue/digital IO, the usual suggestion is to multiplex, read this arduino community
thread and checkout the I2C Expansion page for some further info on how to do that. also worth mentioning, the wiring hardware boards (if i remember correctly, wiring was the original (taking many of the concepts developed in processing and applying them to hardware) and defined the spec, arduino was a bit of an offshoot, implementing the spec) have quite a lot more IO, 43 digital pins, 8 analogue, 6 dedicated (and 6 digital capable of hardware - you could still do PWM in software on digital pins) PWM -- so you might also want to take a look at that. so regardless of what you choose as your hardware platform, i believe you'll want to dive into multiplexing your IO. |
