Using Push Buttons instead of Rotary Encoder on IOCards

[Guest Raafie75]

Hi guys,I would like to know if I can wire my IOCards to have 2 Push Button Switches instead of Rotaries. One to select up and one to select down? The switches I'm using also might be always on (on=1), so I'll have to setup IOCards to switch when they are off (off=0).Look forward to some information.Kind Regards,Brad HellerNewcastle, Australia

Hi Brad,rotaries are basically like 2 pushbuttons (Kitter principle) Of course you can do as you proposed. However you will probably need to make sure that the contacts are open when not depressed and only be on when depressed. Depending on the I/O card it could happen that as long as 1 contact is permanently closed (on) the card would stop scanning the matrix (ITRA / keyboard encoders) and hence not recognize if another pushbutton is depressed. FSBus could handle this with no problem.Hope this helpsBRPeter

Thanks for the info Pete.From what I can understand within IOCards under "SW-NORMAL" you can tell it the state (whatever it is), which is on. Eg. "0" or "1" can be on. Can anyone tell me if I'm wrong, I'm only new to IOcards.Can you enter 2 different lines in IOCards under "SW-NORMAL", one to cycle up and the other to cycle down?I've already built FSBUS boards but have changed to IOCards because of their ON737 Software soon to be released and the support provided.Regards,Brad Heller.

You'll like the idea and functionality for about 5 minutes. Depending on what you plan on using the pushbuttons for, you might be sitting there a long time pressing these buttons to change a heading bug, select a new altitude, etc... it's a lot of pushbutton events to go from a heading of 080 to 260.

The actual reason for asking the question was to find out if I could get a Knitter type output to work with IOCards. The way I asked the intital question was the easiest way I could put it without confusing someone. My intention is to use a Rotary Encoder through REDec but attach the 2 outputs to a input on IOCards. REDec basically gives an output like a knitter switch but both outputs of REDec are always on, so I had to make sure it could handle the "always on" function aswell.I've recieved an answer from IOCards that their software "SIOC" will be able to handle that problem. I'm yet to read up on the program just as yet. If I can use REDec isntead of their Encoder board, then that will save me alot of money!Everything is twice as expensive to most of you guys because we have to order in U.S. dollars and the Aussie dollar isn't that strong. I'm dreading the day I may have to order Project Magenta, the package is going to cost me around $1,000.00 Australian.Regards,Brad Heller.

If you use SIOC system, this is very easy.You only need to define a timer with value of your repeat action ( in sec/100 ).You define a condition in this timer when you have push the buttom and launch action. For example, increment or decrement value of course. It Is easy...A example of use for those operations, is EFIS of a 737-NG in MINS and BARO functions !

I was thinking more of tuning radio's?Brad.

[kiek 1,215]

Brad,You cannot connect a "Knitter" type rotary to IOCards and have it treat like a Rotary. You only can define a function for each of the separate inputs, but not the nice build in feature of the IOCards with respect to rotarie support (such as increment specification, increased increments when you turn faster, ...) like you need for radio's.You better use grey type encoders, you can connect them directly to IOCards and they work great. You can order them from FlightDeckSolutions for just 4.50 Dollor each. No encoder cards needed.I have spent some text on experiments with diffrent types of rotaries and IOCards on my web site, www.nicokaan.nl mcp page, section Rotary encoders and IOCards, at the very bottom.Best Regards, Nicowww.nicokaan.nl

Hi,I'm using the IOcard with special knobs I made. Those knobs are actually two pushbuttons operated by a knob (see attachment)I'm using the new SIOC software from IOcard and it works well.I used my specials knobs for all rotary like control and to increment or decrement faster, I'v installed a "multiplier" switch on my yoke, so when I'm holding the switch on the yoke while using the knobs, it increase or decrease a lot faster.Just take a look at my site for details.And here's the code for the SIOC software (not complete yet) but you could use it as example.Bye

Thanks Michel, just what I needed to know!Looks like alot of programming with SIOC !Is it hard to learn, do you have to know a programming language or is the manual self explanitory ?Regards,Brad Heller.

[kiek 1,215]

Hi Michael,Nice solution! I have to study the details of SIOC as well. However, don't forget that you are now putting software 'on top of' software (which is prone to erros) while there is a simple hardware solution: use gray type rotaries and connect them directly to the Master Card (of IOCards) and each rotarie individually can be defined a separate increment and speed...Remember the KISS principle: Keep It Simple (Stupid) ;-)Regards,Nicowww.nicokaan.nl

[Guest Raafie75]

Nico, its a little hard when you've already ordered Aus$207 of encoders.Brad.

[Guest CaptnKebec]

No it's not really hard, the better way to do it is step by step.I did it control by control and with trial and error.The manual is not very explicit, I had to learn by trying.I'ts not like a programming language, you just hook switch event to actions.I began with just one knob and continue to ad code until all the knobs were done.I know it's easier with encoders, but my goal is to build my sim with things I already got or at a minimum cost. I prefer building my controls instead of buying it.Of course I am a programmer so it's probably easier for me to use the SIOC software.If you want I can send you the actual code file, so you can play with it.

[Guest Raafie75]

I'd appreciate if you could send that file.Email to: bwheller@optusnet.com.auRegards,Brad Heller.
