[Hardware, Plugin] Arduino based physical display + serial port io+ tutorial (24-11-19)

[stibbons]

Glad you figured it out in the end. But CKAN definitely has the most recent plugin; I switched from my local development build to the CKAN version as soon as hakan updated the entry. Have you updated your local registry recently?

[ArduinoProblem]

I have a few problems :

I dont know where i must put the plugin in the KSP-folder and i dont know how which code of the four of the demo is the right one....

please help

(Sorry for my bad english...)

The plugin goes into the GameData folder, similar to other mods.

For the Arduino code, if you open KSPIODemo10.ino (and you are using the Arduino IDE), you should see other "tabs" that contain the other ino files. When you compile and upload to the Arduino, they are all uploaded.

I'm having trouble getting the tutorial code to work from the first post. When I go to the launch pad, the RX LED on the arduino will start rapidly blinking. It says "Starting serial port COM3" at the bottom right corner of the screen and the log says: KSPSerialIO: Handshake received - 314. But none of the 3 LEDS ever turn on.

This is how it's connected up:

I've confirmed all 3 LEDs work using the basic Blink arduino sketch.

Any ideas what's going on?

Good to see you got it working! For future reference, if you are getting the handshake reply but not getting any data, it usually means you found the right COM port, everything is working but there is something wrong with the packet. This is typically caused by plugin and arduino code version miss match. This must have happened 3 or 4 times in this thread, I should probably put something in the first page.

Based on the circuit diagram in the first post of the thread by zitronen, where in the diagram is the input from the computer? All the inputs on the arduino controller seem to be connected to LCDs

[stibbons]

Comms with the computer happens over the Arduino's USB connection.

Is there any date on when the ability to go to map view might be added in?

EDIT: And maybe the ability to see what celestial body i am on/above/orbiting

I would love to be able to change this.

I think map mode is a pretty long way ahead, if it had been uncomplicated it would have been here long ago. SOI is just a matter of zitronen deciding whether we get a number or a name.

I'm waiting for 1.0 to hit before making any more changes. I have a feeling that lots of things will need changing.

[zitronen]

Good news everyone! The plugin seems to work OK from preliminary tests in sandbox mode in 1.0!

[stibbons]

Great news!

EDIT: preflight checks for my panel were all solid, and I've had a few successful missions. One spectacularly unsuccessful mission as well, but we're currently blaming Jeb for that.

I was just about to ask if there had been an update about this

Great to hear!

All green on career mode as well. I am a

Ok lads, I need some help, I run the demo sketch as im a noob and the lights do what they should but the throttle stays on ?? What am i missing here? I have uploaded a video to explain more clearly :s

It's hard to see from you video, but are you using an analog pot for throttle?

If you are not, just set throttle enable to 0 in the config xml file.

[Freshmeat]

On launchpad, the rocket starts halfway throttled up. Default config is that your controller overrides iff default controls are at zero. So throttle down to zero on the keyboard and see if it helps. Then, in ..\gamedata\KSPserialIO\plugindata? there is a config file. Open it and change <int name="ThrottleEnable">2</int> to <int name="ThrottleEnable">1</int>. It disables the keyboard throttle and always uses your controller.

[stibbons]

I think that 0 might be a better default for the throttle than 2. It's the "least harm" option.

[Kerbal007]

Thats the thing, ive not edited any config files, and I don't have a throttle set up, just the keyboard, I was wanting to see if I can make the lights work first

[stibbons]

Yep, editing the config to disable throttle control by the plugin should set you straight.

[Kerbal007]

Having a look now, Thanks stibbons

:EDIT: Awesome, now to learn how to expand on that. I think next on the list is getting the Yellow indicator to turn off once the red indicator fires as it would no longer be necessary to have this on at that point

I'm pretty sure we defaulted it to 2 because someone complained that analogue throttle wasn't working .

Is any one having any problems at all with 1.0? I've started my career mode, seems ok so far. If every thing is working I will look into adding SOI names next. I'm still thinking sending full name char array, since they haven't added any new planets.

[Kerbal007]

So far so good Zitronen, I don't really know what I am doing but keen to play and learn, I think today I will look at a launch button

Hes is my amended video

[Freshmeat]

@zitronen: I am all good after a couple of hours of play, only need some recoding once I get a better knowledge of the new drag model. Looking forward to SOI names.

@Kerbal007: Welcome, share your ideas and questions, we learn a lot from each other in this thread.

Hmm, ïf you put it like that, then let me share something that's been on my heart for a little while.

I wanna learn arduino. Really bad. But i really suck at coding. All the coding/C++ i can do, is copy templates from a book into Arduino Sketch ... Oh yeah, and if there is some code, where numbers like timing and such comes in play, i do understand that quite easily, for some odd reason, but that's about it really.

But what i also have that might help, is an Arduino Starter Kit, that comes equipped, with what i can only assume is just plenty enough, to get started on my own KSP hardware, and hopefully, learn something about it too as well.

tl;dr, i'm too stupid to arduino currently, where do i start?

[Freshmeat]

Do a truckload of example sketches and try to change little things in them first. Try to guess the meaning of the words you are writing and how you can do something a little bit different. Learn how to use a switch. Then learn how to use a switch to assign a value. Learn how to use a potmeter, and how to do simple math in Arduino C so you can assign that value. Then try to change something simple in zitronens code. It is quite a road if you start from scratch, but a highly rewarding summer could await you.

I don't know the contents of the starter kit, but a breadboard, switches, a couple of LEDs and 1k resistors, and a slide or rotary potmeter goes an extremely long way.

Programming is all about breaking complex bits into simple bits, and then solve them one by one. If you read zitronens code, it is rather user friendly in form documentation on how to change simple things. And if you can ask a specific question, some of the gurus around here are very friendly and helpful.
