Hi guys,
after dozens of attemps and hours spent to understand why SIOC/OC4BA doesn't read my Overhead Panel's encoders properly, I try to ask here in the forum about my new issue.
I'm using the rotary encoder linked below (FLT ALT and LAND ALT rotary encoders):

https://www.sabdel.com/shop/electronics ... ray-scale/

It's a 2-bit gray type encoder as you can see. Encoders are connected to an Opencockpits "Input connection + Encoders" Card like this:

http://www.opencockpits.com/catalog/inp ... Path=21_27

Encoders are connected directly to the card's standard inputs.
I try to test the script below, but it doesn't work properly. The digit display seems to be crazy!!! I think there's a problem on SIOC encoder reading.

Here's the script I tested:

Var 0598, static, Link IOCARD_ENCODER, Device 30, Input 108 Aceleration 3, Type 2 // Encoder input for FLT ALT
{
L1 = &FlightAlt
L0 = 500 * V0598
&FlightAlt = LIMIT -1000 ,42000 ,L0
L2 = &FlightAlt
IF L2 > L1
{
IF &PRESS_F_ALT_K = 0
{
&PRESS_F_ALT_K = 1
}
ELSE
{
&PRESS_F_ALT_K = 0
}
}
ELSE
{
IF &PRESS_F_ALT_K = 8192
{
&PRESS_F_ALT_K = 8193
}
ELSE
{
&PRESS_F_ALT_K = 8192
}
}
}

I tried to change aceleration number, but nothing different happens.
Thank you in advance for responses.
Best regards

Hi Marco

I wrote a new compact script for the flight and landing altitude. Adjust encoder inputs to your setup and then it should work:

// Flight and Landing Altitude

Var 2700, name PRESS_F_ALT_K, static
Var 0598, Link IOCARD_ENCODER, Device 30, Input 126, Aceleration 3, Type 2 // Encoder input for FLT ALT
{
L0 = -50 * V0598
&FlightAlt = LIMIT -1000 ,42000 ,L0
&PRESS_F_ALT_K = 0
IF L0 > 0
{
&PRESS_F_ALT_K = 16384
}
ELSE
{
&PRESS_F_ALT_K = 8192
}
}

Var 2701, name PRESS_L_ALT_K, static
Var 0599, Link IOCARD_ENCODER, Device 30, Input 128, Aceleration 3, Type 2 // Encoder input for LAND ALT
{
L0 = -50 * V0599
&LandAlt = LIMIT -1000 ,42000 ,L0
&PRESS_L_ALT_K = 0
IF L0 > 0
{
&PRESS_L_ALT_K = 16384
}
ELSE
{
&PRESS_L_ALT_K = 8192
}
}

Please let us know if you succeeded.

Hi Marco

I made a short review and found an even simpler solution . Try this:

// Flight and Landing Altitude

Var 2700, name PRESS_F_ALT_K, static
Var 0598, Link IOCARD_ENCODER, Device 30, Input 126, Aceleration 3, Type 2 // Encoder input for FLT ALT
{
&PRESS_F_ALT_K = 0
IF V0598 < 0
{
&PRESS_F_ALT_K = 16384
}
ELSE
{
&PRESS_F_ALT_K = 8192
}
}

Var 2701, name PRESS_L_ALT_K, static
Var 0599, Link IOCARD_ENCODER, Device 30, Input 128, Aceleration 3, Type 2 // Encoder input for LAND ALT
{
&PRESS_L_ALT_K = 0
IF V0599 < 0
{
&PRESS_L_ALT_K = 16384
}
ELSE
{
&PRESS_L_ALT_K = 8192
}
}

Works perfect in my cockpit.

Hi Urs,
after hundreds of attempts, finally I decided to use Opencockpits CTS288 type encoders for FLT ALT and LAND ALT:

http://www.opencockpits.com/catalog/enc ... p-100.html

Encoder central pin is connected to GND, and the other pins to two consecutives inputs in the same Input card group. No encoders' push button implemented.
Are your scripts good also for CTS88 type encoders?
I tried running scripts you suggested me, but encoders work fine only in one direction (e.g 0,500,1000,1500 and so on).
Numbers can't decrease as I rotate encoders in opposite direction.
Any suggestions?
Best regards.

Marco

Hi Marco

Please check the following:
Be sure that the two consecutive inputs from encoder are correct and not shifted by 1 up or down. Sometimes numbering is confusing...
Then verify by sending commands from IOCP console, that the values 16384 and 8192 change the altitude up resp. down in your setup.

Best regards
Urs

Hi Urs,
after 9 months I finally solved my problem!!! Input connections were OK, I simply replaced your script with Roar script:

Var 0598, static, Link IOCARD_ENCODER, Device 30, Input 108 Aceleration 3, Type 2 // Encoder input for FLT ALT
{
L1 = &FlightAlt
L0 = 500 * V0598
&FlightAlt = LIMIT -1000 ,42000 ,L0
L2 = &FlightAlt
IF L2 > L1
{
IF &PRESS_F_ALT_K = 0
{
&PRESS_F_ALT_K = 1
}
ELSE
{
&PRESS_F_ALT_K = 0
}
}
ELSE
{
IF &PRESS_F_ALT_K = 8192
{
&PRESS_F_ALT_K = 8193
}
ELSE
{
&PRESS_F_ALT_K = 8192
}
}
}

Your script didn't work for me, Urs.
BUT another problem comes out!
When both encoder inputs labels are green in SIOC monitor, all inputs belonging to rotary encoders' inputs group start flickering without any reason.
When only one encoder input label is green, everything is OK.
When both encoder inputs label are white, everything is OK.
Any suggestion?
Best regards.

Marco

Hi Marco

Verify that flickering is off with each of the two inputs switched (one or the other green). --> if not, check corresponding input wire for short circuit. If yes,check ground wire of the group
Does flickering appear also when another encoder of the group has both inputs green? --> check ground wire of the group

Best regards
Urs

Hi Urs,
problem solved! I'm using an Opencockpits "Input connection + Encoders", not a simple Opencockpits Input card.
I hadn't feed card with 5V!!!
Thank you anyway for your cooperation Urs.
Best regards.
