kcanrah Geschrieben May 7, 2012 at 18:06 Share Geschrieben May 7, 2012 at 18:06 Can you make a number pad bricklet? I think it would be very beneficial for a lot of projects like alarm systems. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...

Christian Geschrieben May 7, 2012 at 20:04 Share Geschrieben May 7, 2012 at 20:04 perhaps you could realize a numberpad via io16 bricklet... there could about 16 switches connected or am I wrong?? :-) Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
batti Geschrieben May 7, 2012 at 20:06 Share Geschrieben May 7, 2012 at 20:06 No of course, you can do this. But I see the point that a special bricklet would be easier to use, Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
Christian Geschrieben May 7, 2012 at 20:19 Share Geschrieben May 7, 2012 at 20:19 yes of course. a bricklet with a 3x3-foil-Keyboard would be cool. like an access control or simmilar :-) Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
kcanrah Geschrieben May 8, 2012 at 19:20 Autor Share Geschrieben May 8, 2012 at 19:20 I think that 2 buttons wouldn't be bad to do with an IO bricklet. But a nice backlit number pad would be a lot nicer than connecting all of those buttons to an IO bricklet. If you make one and need someone to test it I will be more than happy to!

nichtich Geschrieben May 30, 2012 at 15:21 Share Geschrieben May 30, 2012 at 15:21 In the German forum I suggested a GENERAL INPUT DEVICE brick, where you can plugin in devices via USB, PS/2 and RS-232. This works for keyboards, joysticks, and handheld barcode scanners, among others. Used keyboards, joysticks and similar devices are cheap, so why not reusing this old PS/2 or RS-232 hardware? The protocol just sends key scan codes as events if a key or a button has been pressed or released, this has not changed much in the last decades. Such brick would allow easy input to your applications. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...

Xenna Geschrieben July 16, 2012 at 17:34 Share Geschrieben July 16, 2012 at 17:34 I'm not that great with housings and stuff, so my ideal device would have a nice case around it. A number pad with arrow keys and an LCD screen, come to think of it, that would be EXACTLY like my house alarm system With a nice case so that you can easily mount it on the wall and control all your Tinker stuff with it...

In some applications you may only need two buttons, in some others a number pad ... TI currently promotes an capacitive input method with their MSP430 controllers, and there is a paper on that here http://www.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=slaa379&fileType=pdf So, as an idea, just make a PCB with enough capacitive fields (at least 4x4 fields, more would be better), which could then be grouped together in software. You could add a piece of transparent material into the kit, to cover the PCB and let the user place a piece of printed paper between that and the PCB, to label the sensitive fields. Such a construction would accommodate those that just need a button or two as well as those folks that need a full number pad. If there were enough capacitive fields , one could implement anything from one large button to sliders and wheels. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
