outputs problem

[B763]

Hi everybody. I have a strange problem with my Opencockpits outputs-card. The card is connected via USB which is feeding +5V for card itself, an additional +5V is coming from PSU which is feeding actual outputs. When i test the card with software everything is ok, leds are illuminating and average +4.3V are coming from each output.

However when i run the board via SIOC, Lekseecon & Level-D lights turns on as meant to be, but are very dim??? Looks like it is not a hardware problem, connections, jumpers etc are ok. Could there be a line in the script that affect and dim my leds?? The script what i am using and editing is "Mick's LD767 code for Sioc" Other opencockpit cards connected now are, 2xmaster, 2xdisplay, 1xoutputs..

Regards

Anybody? I am pulling my hair right now..:-(

I don't personally deal with sioc. But the most common reason i know for this is if an output pin is set as an input. Due to the physics the leds will light but only dimly

Hi

It's probaly some in the SIOC script which dims the light. Have you tried with some simpel lines in SIOC, perhaps
only one LED and see how it light up ?

Hi,
Are you aware of the fact that the outputs at a USB outputs card share a common +5V? IOcards of Opencockpits (http://www.lekseecon.nl/iocards.html#USBOutputs)

If you measure +4.3V at the output, it means a '0' if you measure 0V it means a '1' and the led should lit.

If that does not help, please post the SIOC script that you are using.

Hi. Yes common +5V. The card works perfectly when i use "test outputs" or "sioc monitor", +4.3V . When i run it in sim led is very dim and 0.1V is coming out from an active output???:?: I am using Mick's LD767 script from Lekseecon file library (sorry i can not attach whole script here, too many characters). Here is part of it (Vor2). Vor2 panel works (displays, encoders, buttons) but output led for "auto/manual button is very dim:

Hi,
0,1V for an active output seems OK to me. If an output is active it will be around that value.

Ok. Thank you.

Hi, I did not like the sound of this statement, I hope that they are only related by a common 0v?
"Vcc" or 5 volts is whatever it is measured at e.g 4.99v from USB and 5.5v from elsewhere, so alarm bells ring when you mention 4.3v and "dimming".
Power from different sources is fine but only one reference 0v is required. Do make sure there is no inter-action between sources.

Good luck.

Yes, that is the case with the Opencockpits cards, no worries.

The difference between leds having a "common 5 V" versus a "common 0v" is only a local card issue; it tells you to connect the + of a led to the right wire. So it is only a local polarity issue.

Both type of cards work well in my sim.
