Here is my log as requested. https://drive.google.com/file/d/0BywyT2cDCiRoR2pPa2ZSYk1WdlU/edit?usp=sharing

Thanks mulbin for the info.

also, here is something in the log that has to do with the IODemo

OK so for some reason it can't detect the arduino, it is on COM3? Try increasing the handshake delay in the settings .xml file in the gamedata folder

You also seem to have quite a few mods installed, can you try it on a fresh install?

You can also try the new version of the plugin and arduino code in post 317.

[Mulbin]

Try

float drainPerSecond;
float chargePrevious;
...

drainPerSecond = (VData.ECharge - chargePrevious)/VData.deltaTime;
chargePrevious = VData.ECharge;

Ok, sorry, newb questions again.

I assume I put the floats in the list with the existing floats... but where do I put this?

drainPerSecond = (VData.ECharge - chargePrevious)/VData.deltaTime;

chargePrevious = VData.ECharge;

I can't find anywhere to put it that doesn't just throw errors back at me about them not being defined.

[thatsmessedup]

Thanks. I reinstalled the game and used the updated arduino code. It works great now! Iv reinstalled my plugins and save folder and it is still working so It must have been the code I was running or the ksp install was broken.

If you put the declarations in the main tab with the rest of the variable you should be able to put the calculations anywhere.

Alright cool, I thought you found yet another annoy bug.

[Mulbin]

Sorry, still don't understand. What do you mean by "declarations and "Variable", I'm not a coder so don't know the jargon.

I have put the floats in StructVesselData so it now looks like this...

struct VesselData

{

byte id; //1

float AP; //2

float PE; //3

float SemiMajorAxis; //4

float SemiMinorAxis; //5

float VVI; //6

float e; //7

float inc; //8

float G; //9

long TAp; //10

long TPe; //11

float TrueAnomaly; //12

float Density; //13

long period; //14

float RAlt; //15

float Alt; //16

float Vsurf; //17

float Lat; //18

float Lon; //19

float LiquidFuelTot; //20

float LiquidFuel; //21

float OxidizerTot; //22

float Oxidizer; //23

float EChargeTot; //24

float ECharge; //25

float MonoPropTot; //26

float MonoProp; //27

float IntakeAirTot; //28

float IntakeAir; //29

float SolidFuelTot; //30

float SolidFuel; //31

float XenonGasTot; //32

float XenonGas; //33

float LiquidFuelTotS; //34

float LiquidFuelS; //35

float OxidizerTotS; //36

float OxidizerS; //37

uint32_t MissionTime; //38

float deltaTime; //39

float drainPerSecond;

float chargePrevious;

But still can't find anywhere that I can put this...

drainPerSecond = (VData.ECharge - chargePrevious)/VData.deltaTime;

chargePrevious = VData.ECharge;

...without just getting errors.

I either get this...

output:1: error: expected constructor, destructor, or type conversion before '=' token

output:2: error: expected constructor, destructor, or type conversion before '=' token

Or I get this...

utput.ino: In function 'void output()':

output:9: error: 'drainPerSecond' was not declared in this scope

output:9: error: 'chargePrevious' was not declared in this scope

[thatsmessedup]

Got my LCD Displaying some data WOOOHOOO!! Just wanted to make a shout out to the creator of this plugin. Thanks for doing all the dirty, under the hood stuff. That would have been very difficult for a hobbyist like myself. I get jealous looking at all these different control panel mods. I just need to figure out what I want and get the pieces together. OOO, and Im still not quite sure how I am going to hook everything up with just my one uno. I will probably need to do research. I want about 15 buttons/switches with leds and a few lcd... possible an rcs thruster joystick.

[Mulbin]

Could you look at my code and tell me what's wrong? you're not making it very clear where I put the two separate bits of code and it's still just throwing up error messages. I know it's a pain having noobs trying to understand your plugin but I'm not a coder so things you might assume are intuitive to me really aren't Thanks for being patient!

[zitronen]

The declarations are correct, but these need to go in your inputs() function, where you do the rest of your input stuff, dials LEDs and so on

  drainPerSecond = (VData.ECharge - chargePrevious)/VData.deltaTime;
  chargePrevious = VData.ECharge;

"drainPerSecond" is called a variable, when you do "float drainPerSecond" you are declaring that "drainPerSecond" to be a variable that is of the floating point type (i.e. with decimal point), so the next time you use "drainPerSecond" the compiler know what to do with it.

[thatsmessedup]

AAAAAA!! This is what im missing. I was playing around with my pot for a good while and finally decided to search the thread for "throttle". Had to enable the the bit in the config file. Maybe add that to the comments ..

"Weekly" update 8: 0.14.1

Axes! Currently Only throttle, will add others later. You will need to go to settings file and set ThrottleEnable to 1, by default throttle is not enabled. Once throttle is enabled you will lose the ability to control it with keyboard. Connect a pot to an analog input pin 0 and that's it (see arduino.cc/en/Tutorial/ReadAnalogVoltage).

Plugin:

https://sites.google.com/site/zitronfiles/KSPSerialIO_014_1.zip

Arduino:

https://sites.google.com/site/zitronfiles/KSPIODemo4.zip

Once this has been tested I will add more axes and update the first post.

Edit: Unfortunately I'm away to Germany next week, will not be able to answer questions.

[Mulbin]

Thanks Zitronen, it's accepted the code now I'll play around with the formula for the displays later.

[BagelSoTasty]

Before anyone facedesks at me, I'm a total Arduino noob.

I can't upload the code for the LED warning lights, because it claims:

KSPIODemo.ino: In function 'void setup()':

KSPIODemo:58: error: 'initLEDS' was not declared in this scope

KSPIODemo:60: error: 'LEDSAllOff' was not declared in this scope

KSPIODemo.ino: In function 'void loop()':

KSPIODemo:67: error: 'KSPBoardReceiveData' was not declared in this scope

KSPIODemo:71: error: 'Handshake' was not declared in this scope

KSPIODemo:74: error: 'Indicators' was not declared in this scope

KSPIODemo:87: error: 'LEDSAllOff' was not declared in this scope

I have no clue what to do, and I'm amped about this plugin.

[zitronen]

Did you make sure all the files from the KSPIODemo4.zip are included in your arduino folder?

When you open the "sketch" it should include multiple tabs.

Um this is described in the first post!

[8749236]

You've just reminded me my Smart House project in school..

Pretty impressive =D

I never thought of that..

Perhaps you can use that to make your own Space Center at home!..

Another suggestion: Why not just label all the fuels with numbers, then just dispatch the remaining resource values just by numbers.. So you dont need to worry about those words or something...

I'm sure KSC will approve this =P

Duhuhuh! Thank you.

Ok, been a while since I've posted here. Been very busy lately.

Received my 20x4 LCD display and have been fighting with it for a couple of days, finally ironed out my problems and got it working (Hello World! )

And just now (as a proof of concept) had it displaying the 'vertical velocity'

Thanks again for this amazing plugin, will post back when I have something more stubstantial to reporting... Might look at the throttle next...

Any idea what rating pot would be best used to get the full range of it working? 5k? 10K? Obviously need to put it all the way to 100%, but don't want it to reach 100% when the physical throttle is only at 75%...

[zitronen]

5K 10K 100K all should work fine. You can also write some code to make it use whatever range your want.

[pantner]

5K 10K 100K all should work fine. You can also write some code to make it use whatever range your want.

ok, cool, thanks for that. Will see what is available.

[thatsmessedup]

Where did you learn about programing the display like that?

[pantner]

how are you dealing with the 'trash' characters on your LCD? ie, your speed drops from 100 to 99 but the LCD displays 990 because you didn't tell it to stop displaying the last 0 from 100...

**EDIT - also, just realised, there is no orbit velocity reading? or am I missing something?

Edited April 30, 2014 by pantner

[zitronen]

You can simply print some blank spaces where your number is before you print the number every time, or you can use a function such as "dtostrf" to print formatted strings.

I'll add orbital velocity this weekend. Anything else you want added?

[falken]

This reminds me of my SLI PRO interface for racing sims, good job!
