Getting Long Data

How do you get a Long (signed or not) from the FRC to you?

I'm currently using printf() in a way so that, basically:

Code:

void printl(long Num)

{

 //Print Bytes

 printf("Long %d %d %d %d\n", (int)(Num>>24)&0xFF, (int)(Num>>16)&0xFF, 

     (int)(Num>>8)&0xFF, (int)Num&0xFF);

 

 //Print Words

   printf("Long %d %d\n", (int)(Num>>16)&0xFFFF, (int)Num&0xFFFF);

}

The problem is that the thing seems to want to increment higher sections to soon. In a pattern.

Code:

:confused:
(or:

Code:

...

0 8

1 9

...

) :confused:

The other option is to use 4 user bytes. but we only have 6. well, 4 User + 2 LED + 1 UserCmd.

Can anyone offer suggestions? This little bug really affects results. (bland understatement)

The problem is that you're printing out each byte of the long as a base-10 number. Try using %x instead of %d. That way, you'll get the right numbers out, but they'll be in hex. If you want it in decimal, your best bet is to modify printf_lib.c (specifically the printi function) to accept long arguments.

I just put some routines here http://www.chiefdelphi.com/forums/showthread.php?t=26529 that do this.

You can just call the one routine that prints decimals without changing any of your own printfs.
