poor little newbish programmer needing help
 

Hi, I am new to programming and I don't know much about it but I am slowly getting it and first I would like to know if there is a guide that goes more in detail about programming in the buttons on the joystick, I probably have something but I have hundreds of pages of stuff and have no clue on what I need to know.
But my major problem now is putting in the new code in the....robot controller, ya thats is!, I hold down the prog button on till the program state led is orange and click download. it finishes and a window pops up....now I have no clue what it is, it had a ton of x=0 and y=0 stuff scrolling down, we left it going for about 5 minutes and still going, Which might be our problem I never found anything on it so I wasn't sure what it was supposed to do or if it was of any importance. We got out of it and followed the instruction in he "2004 Full-Size Robot controller Reference guide" that I got from FIRSTS website or maybe here I don't remember, we tried it 3 times and it still won't upload the new code. But all we are trying to do is put a 2 joystick drive into 1. Which was on an older code and I put in that code part for 1 joystick which I checked that thing a million times and saved it. and I made sure I was loading the right code, but it still won't go! I brained my hurt. :confused:
So please excuse my bad spelling and grammar and Thanks in advance for any help. I hope I typed it in a readable manor.

EDIT Hey theres a spell check button

Re: poor little newbish programmer needing help
 

go to the FIRST website and in robotics section there is a specific guide to programming.

Re: poor little newbish programmer needing help
 

There is a vast amount of programming information availibe to you either

through this website, the IFI website or various other members personal websites dedicated to programing (Kevin Watson comes to mind)

here are a few links i found just searching the Programing Forum here on CD

http://www.chiefdelphi.com/forums/sh...ad.php?t=30976 (a programmers guide so to speak)

http://www.chiefdelphi.com/forums/sh...ad.php?t=32870 ( the 2005 automode scripting manual)

and last but not least http://www.chiefdelphi.com/forums/se...earchid=447110 ( a search of the site using the terms progamming the RC)


I hope that helps,

Hey Josh, welcome to the wonderful world of programming. The learning curve is a little steep at first, but once you get started , it comes faster. The document you already have is a great help and does have info on setting inputs to outputs and or actions. It is not really detailed, but pushes you in the right direction.

The window that popped up is a terminal window. It is displaying the data that is being sent to it by a "printf" command. You can probably find the line calling it in the user_routines.c file in the "Process_Data_From_Master_uP" function. It will be somewhere around line# 190, depending on what modifications you may have made to the file.

I think what your saying is you are trying to set up the drive system for single joystick drive, correct? If so, the default code already handles it. Look near line 240 of the default code. There is a comment block that describes how to hook up the drive motors and the code that mixes the X and Y axis of port 1. It's all there already for you.
Hope that helps.

Re: poor little newbish programmer needing help
 

Thanks yall.
But we had it set to 2 joystick and we are trying to load the 1 joystick code but the thing never...uh well downloads. It goes through the download process the terminal window pops up and then thats about as far as we can get it. We followed the instructions in the paper I mentioned earlier but it doesn't like me :(
Sorry if I am being vague But I can't help it :(
But we MIGHT have 2 people helpin' us tomorrow I hope they show up. :D
EDIT: And I allready went to the FIRST web site. I downloaded that long video and it helped a bit but didn't help me to much
But thanks for that autonomous mode thing. I will have to play with that for next year :D

Re: poor little newbish programmer needing help
 

are you the only person doing pogramming on your team?

Re: poor little newbish programmer needing help
 

Unfortunately Yes, our old programmer graduated and....well he said he wasn't going to help us....But supposedly he is going to be there tomorrow but well see. We do have a few mentors who can help us but I didn't think I would have the problem loading in the code :(
And I am going to try and go through everything I have to see if it can help me before out meet tomorrow. Sometimes I REALLY don't like computers :D
EDIT: And we have only 6 current members 2 are more on the PR side so they aren't relay knowledgeable in much of the robo stuff, we have 1 who is doing a lot of the design and 1 electrical. The 4th is our Friend who we kinda dragged into this :D but he has some decent tool knowledge. And we have 2 mentors helping us on alto of the build. But we were kinda amazed at how many people were on the other teams. Seeing 90 people to our 6 kinda makes me think that I really do live in a "farming community" to say it nice :rolleyes:
EDIT 2: Man I have bad grammar
EDIT 3: I like your pancake bunny

Re: poor little newbish programmer needing help
 

How are you so sure it never downloads? If the program state led turns green, it probably did download correctly. If the terminal window pops up, that probably also means that it worked. Did you actually try moving the joysticks to see what they do?

Re: poor little newbish programmer needing help
 

...ya know, you might just want to check that the file you are selecting in the IFI loader window is really the file you WANT to load. I can remember times of loading the frc default file by accident - all the while thinking it was our modified version. ...just one of those silly things... :rolleyes:

Re: poor little newbish programmer needing help
 

We tried moving the joysticks everytime and the samething happened.
And I am almost positive that I was loading the right file. That was something I thought of and checked it out many times.

Re: poor little newbish programmer needing help
 

Josh

I am confident that the code is getting downloaded to the RC correctly, and that there is some other problem with your setup.

Since you're seeing the "x = 0 y = 0", try this...find the line in your code that is doing the console print. It will look something likeChange the "x = " to "x2 = ", recompile and download your code. This time if you should see "x2 = 0 y = 0" scrolling on your console you know that your code is being downloaded correctly. (When you're done with this test, don't forget to change the x2 back to x)

Moving on, here is a list of things you may want to check...

1. Do you have the joystick in the right port? I think that the default code uses port 1.

2. Do you have the motors connected to the right outputs on the RC? The default will send the right drive signal to PWM13 and PWM 14 and the left drive signal to PWM 15 and PWM16.

3. PWM outputs 13-16 are a little different than 1-12 in that the user has to specifically generate the outputs. This is called as follows and should be found in the Process_Data_From_Master_uP function after the call to Default_Routine.4. Is your robot enabled? Most teams create an enable/disable switch so that the robot can be safely disabled while debugging. If you aren't using one, I would highly suggest making one for your safety and the safety of anyone within arms reach of your robot. Plans can be found here

If you're still having problems after checking the above things, post your user_routines.c and we can take a closer look as to what your program's actually doing. (Don't forget to put it in a code block if you do)

By the way, Mark McLeod started a pretty good thread about starting to program FIRST robots. You may want to take a look here.

Re: poor little newbish programmer needing help
 

Well I am going to check everything cause I am about to go to my robotics meet in a few secs, but first
1. Ya we check the controllers in all the slots and it was the original code.
2 I am not personally sure but the person doing electrical says it in the right ones.
3I'll check this as soon as I can. My laptop didn't have the correct port to program into the bot so I had to use a different one so I am going to see If I can borrow it till after the competition.
4 I don't think we are using one but I'll talk it over with my electrical guy to see if we can do it.
I'll try and use a different code this time as well. Cause the code for the robot is the one from out last composition so he might have dint something different to it and I'll get a clean one from the website.

Re: poor little newbish programmer needing help
 

OK, We got it fixed! A guy named Jason and Flo...Not sure how that is pronounced or if that is even right, I'm kinda tired and hyped up on caffeine. There wasn't anything wrong with the programming :D. Jason said the terminal window having all 0s had to do with the controller. Apparently something was wrong with one of the victors or the wiring and it runs now! ITS ALIVE!!!!
So thanks for the help guys. And know it looks like after seeing Jason work with the programming, he added some stuff and cleaned it up a bit, we will have another programmer :eek:
Thanks y'all!

Re: poor little newbish programmer needing help
 

Glad to see you fixed up your problem.
