auton variables

Technical Programming
1

I am trying to create an autonomous program. Currently I just have everything where it says “add your autonomous code here” however I would like to change it. What I want to do is have some variable like say slow which I could put in my autonomous to make the motors drive at half speed. From what I have read I have to define my variables in the user routines fast.c file like this

/*** DEFINE USER VARIABLES AND INITIALIZE THEM HERE ***/
#define slow

however I don’t understand how that would know to set pwms 14 and 15 to 190. I am missing a large portion of the puzzle.

I’d declare my variable like this:

/*** DEFINE USER VARIABLES AND INITIALIZE THEM HERE ***/
int slow;

and further down:

void User_Autonomous_Code(void)
{
slow = 190;

and then even further down:

/* Add your own autonomous code here.*/

pwm14 = slow;
pwm15 = slow;

I’d suggest starting at the beginning and doing some reading on basic C. There are a bunch of whitepapers: http://www.chiefdelphi.com/forums/papers.php?s=&categoryid=6&perpage=10&direction=DESC&sort=date

These look like good candidates:

Thanks for your help, I had already read some of those white papers, however I was confused by them. Also how do you add the code quote to your posts?

code]printf(“Hello, world!”);

 (without the first space) yields

printf(“Hello, world!”);
