I am having a problem however getting the throttle to work. I am on windows 10, which may be causing problems, but everything else is working so far (SAS controls, LED warning lights, staging), so i'm not totally sure. I did try the debug tool that KingLuxor made and that wouldn't connect to the serial port. 

Has anyone else had any problems like this? It seems like things mostly work, except for the throttle and debug tool.

Are you using genuine arduino's or things ordered off amazon / ebay?

I recently ordered some arduinos, so hopefully i'll be able to make a mini control panel or something :) (Unfortunately shipping from china takes ages :( )

To make sure i understand correctly, the arduinos and computer is linked via a USB cable, right? In the posts above there was a mention of a " usb->ttl adapter", not sure what that is :( 

Expand  

Yes arduino's are connected via a usb cable but there are some issues that I'll outline below that make a usb ttl adapter needed.

A usb ttl adapter is basically a usb thing that converts usb commands into serial commands which allows you to control an arduino. All arduinos have one built in but a driver issue makes the genuine arduino not work correctly on Win10 so the question above actually matters in this case because most ebay / amazon ones tend to use what's cheaper since they're selling it for cheaper, however in this case the cheaper usb to serial adapter works better. So you're bypassing the bulit in arduino usb serial adapter for a cheaper one that works with win 10.

Ohh ok. I was worried i had to buy more hardware :/

Hmm also not working for me [on windows 7]. Looking through the log file, i see this:

The arduino sketch i am compiling is KSPIODemo13.

 

(The arduino is connected through COM13)

 

PS: for some reason i the reply box is glitched and i cant get rid of the thing quote below :(

Here is my list of suggestions for this mod (in order of importance)

-Control SAS vectoring (prograde, retrograde, etc), also send this to the arduino.

-Send info needed to dock (not sure about what's needed)

-switch between orbital/surface/target mode on navball

-time warp controls 

-send state of conection (eg whether you have a connection to KSC)

 

Thank :)

If I figure out how to compile C# code, then I would be glad to give it a shot my self. (As the plugin is open source) :)

If you read thru the 60 odd pages (and I don't blame you if you didn't :P When I first joined up it was only about 30 I had to go thru :wink: ) - @zitronen commented:

Ok so we are using 189 out of 255 bytes in the packet, so 66 bytes left. It's not a disaster if we run out of bytes, since we can just add another packet. However, since RAM is very limited on the AVR chips (255 bytes is a large chunk of RAM!), I would still avoid using too much.

Expand  

So we are running out of 'space' for what we can send / receive to the arduino and the game. 

Some of these are shortcuts which you could send as 'keystrokes' over the arduino; the others -- well, that's up for discussion with the almighty creator / curator  :D

Hi everyone. It's been a while scene I played around with the Arduino. I got everything hooked up for the warning LED demo. I can tell I am receiving a handshake (green led turns on for about a sec right before the Launch pad loads.) and I am getting a IO Awake and No Display Found notification on the top right of the screen. I am running Windows 10 and KSP 1.1.3 using a Arduino UNO. All LEDs have been tested so I know they work. I'm really running out of ideas as to why this won't talk. Any help would be appreciated. Thanks.

Didn`t  Stibbons have some vectoring stuff for his navball? Maybe he can enlighten us about it. I would like to know more too :)  

Anyway, having more stuff is always nice (docking aid would be cool, but again, it only about target vectors. Damn vectors! :D ), but having more you need more compute power and also something to show that info. Not all the time you need all the info.

Just wondering, what is ControlPacket.AdditionalControlByte1/2 ? Can't seem to find a use for it in the code. 

Anyways, i got the plugin to send the SAS mode to the arduino correctly, working on receiving the mode now; will send a pull request when i finish :)

Different vectors. I was only interested in outputting orbital vectors to display on a navball, @c4ooo is talking about changing the SAS mode. 

My stuff is... not in a working state. I declined that pull request until I've picked up a better understanding of how things work behind the scenes.

Probably Windows 10 compatibility issue.

Edit: wait you are using 1.1.3? Which version of the plugin and arduino code are you using?

They are just pace holders for things we have not implemented yet, prograde/retrograde could use them at some point.

If you can get them working that would be great. All the SAS control stuff should fit in one byte, so shouldn't be too bad for packet size.

This is 100% behavior of kspio on w10. LED turn on and off during loading and thus plugin start means your arduino recived handshake (like "hey, are you KSP Display?") but whatever reason on win10 even your display respond correctly ("yes I am KSP Display") plugin will ignore it. Sadly no permanent fix atm. Workaround 1: disable handshake and only recive data. Workaround 2: get ch340 usb-ttl convertor (1$ on ebay)

Aaaah, sad to hear. I was interested more in your work. Realy cool stuff!  

About SAS mode and etc. Here is link to topic about "same" issue. Somebody try to make keybinds. I am not expert but i belive those exact commands could be impleneted and send in packet by ksoio. Looks simple enought :)

 From what I was reading, I thought that the Windows 10 glitch was for inputs to KSP only.

@Mattew is correct, you need to disable handshake in the cfg file, and manually set the COM port in there as well, then it will work but without inputs. I probably need to add something to the first post to explain it better.

Also 18.3 is not compatible with KSP 1.1, please see first post for info.

Setting it to 1 will disable the handshake, correct? And I should set the com port to the same one the arduino software uses to upload sketches?

Do you guys think the arduino should receive what autopilot modes are available? 

Edit: setting / receiving SAS stuff works now :)

Edit 2: Pull request (hopefully) created :) [And hopefully works :P ]
