My master card is working, and I found 30 odd common cathode 7 segment displays I can use for my displays.I just can't seem to get it to work...I have breadboarded 2 7 segment displays and connected them to the displays II card. I'm 99% sure I have them hooked up correctly. What I'm not sure about is the jumper settings, and how to test the card with the software...The 4 jumpers next to each other- I have only 1 display card, where do I set this jumper? Which connecter should this card be plugged into on the master card?There is another jumper right above that one- What is it? Do I need connect 5V to this card or not? I have 5V connected to the master card.In the software- How should I test my displays. There is a box that is looking for a number from 11-55. What the heck is that? What do the other buttons do?Any help would be appreciated- the documentation is not helping me at all.

Hi>The 4 jumpers next to each other- I have only 1 display card,>where do I set this jumper? Which connecter should this card>be plugged into on the master card?Up to 4 DisplayII cards can be connected to a Mastercard. The jumper is there to give it a unique number and thereby defines the numbers of the 16 7-segment displays controlled by the card. I would suggest to set it to the first position.>>There is another jumper right above that one- What is it? Do>I need connect 5V to this card or not?

What the heck is>that? What do the other buttons do?If you would have read the documentation, you should no that...First press the Start button, at the right hand bottom cornerIn the IN/DPLAY you type the ordinal number of your 7-segment. It's probably 11 if you started with jumper section 1, and you took the first 7-segment display. Ottherwise just try. In the Digit (0-9) filed you type the number you want to be displayed. 0-9 are normal numbers, 10 = blank, 11 = - >>Any help would be appreciated- the documentation is not>helping me at all.Don't see you point. There's plenty of documentation in the English language. Just take your time to read it carefully. I and a lot of others managed to do that as well...RT[F]MNicowww.nicokaan.nl

Thanks for your help.I am finding the website is organized terribly, and much of the documentation is out of date.I certainly can't find anything that would tell me why the first display is number 11 in the software? It's not in the software manual.It's just sloppy. I am a programmer, and this single line is a real gem:"Just remember that the IOCard program will read the file configuration (iocard.dat) stored in its same path. We can have several configurations but we have to rename it to iocard.dat if we want to make it active"So, the program can't remember which file you want to load? That would take less than 10 lines of code to accomplish.I like the IOcards- but the software and the documentation are bad. When I finally do get a grip on the software, I will offer to rewrite the English manual for them.I have to add: Maybe the non-English manuals are great, but the English manuals are almost worthless. I've read the documentation. It answers almost none of my questions.

Hello !Sure you have many informations, only need a little time to read.In www.opencockpits.com, you have a section for each card.(left of main page) For IOCard DisplayII multiplexed :http://www.opencockpits.com/modules.php?na...showpage&pid=31And in this section you have this diagram for locate your displays and connections :http://www.opencockpits.com/uploads/displa...multiplexed.pdfIn Download section->IOCards Manuals->English you have a step by step manual for Master and display card. (Annex I,II,III and IV).Those manuals has been writed or translated by english users.IOCard program is for easy configurations and newbie users.If you are a programmer, you can use SIOC software, because you can program your scripts and you have total flexibility with IOCards. Also you can select your file program without rename ;-)A problem for the new user arrived to project IOCards is the entry to a new world with many cards, software, electronics knows, manuals, works of others users... Only need... Be patiente ;-)

>So, the program can't remember which file you want to load? >That would take less than 10 lines of code to accomplish.If there would be such a need, yes, but there are probably more important functions to program... >I like the IOcards- but the software and the documentation>are bad.

The documentation could be improved, I agree... But don't forget that OpenCockpits is not a commercial company. They are people that are willing to share their work with others. They are Spanish people and they do their best to translate their documentation into English. One may expect some "coulance" (a French word). >I have to add: >the English manuals are almost worthless. I've read the>documentation. It answers almost none of my questions.Well, again, I had no problems, not at all... and neither Spanish nor English is my native language... Why don't you try to learn some Spanish? ;-)Nicowww.nicokaan.nl

One may expect some>"coulance" (a French word). I understand it's not a commercial venture, and I am willing to forgive them :) I don't even know if the problem is "lost in translation"- the manuals simply don't explain enough.For example:In programming land, and in FSUIPC- the NAV and COM frequencies are read/written to the sim as BCD (binary coded decimal). Basically, 2 four bit numbers put together instead of one 8 bit. Naturally, you have to do a bit shift to read/write the numbers as decimals.I spent about an hour wondering what "functions" were in the config software. It finally dawned on me that these "functions" were simply the BCD encoding/decoding.Why didn't they just say that! One line like "There are special functions to translate FSUIPC's Binary Coded Decimals into normal decimals that will display correctly".I have no idea what the other functions do- the documentation just says something like "we use special functions here as explained earlier".So, although I don't blame them for this, I would like to see them improved.While I am here, I am now having trouble with this:Since the COM and NAV frequencies don't display the preceding "1". How can I have one of my displays show a static "1"?

>Why didn't they just say that! One line like "There are>special functions to translate FSUIPC's Binary Coded Decimals>into normal decimals that will display correctly".Again, that's because English is not their mother tongue. So don't put your expectations too high, buy try to adapt, ....>Since the COM and NAV frequencies don't display the preceding>"1". How can I have one of my displays show a static "1"?? well, well, peculiar, about that topic you may find dozens of examples of how to do that with plain IOCards in the manuals and in the Opencockpits Forum, just search....And if you want to use SIOC instead of plain IOCards, it's even easier: just add 10000 to the final value you send to your display...Nicowww.nicokaan.nl
