Testing for bits in EasyC
 

my team wants to use the USB chicklet with the x-box360 controller

in the FIRSTwiki it explains how to test an individual bit in MPLab
I would like to make sure that code like the following is supported in EasyC

#define BUTTON_5 ((~p1_wheel &0x80)!=0)
I think it should work but there might be some obscure reason why it might not

Confirmations with reasons or denials would be great! Thank you in advance!

Paul recommend we use

dpad_top = (GetOIAInput ( 1 , 3 )&1<<7)?0:1 ;
dpad_bottom = (GetOIAInput ( 1 , 3 )&1<<6)?0:1 ;
dpad_left = (GetOIAInput ( 1 , 3 )&1<<5)?0:1 ;
dpad_right = (GetOIAInput ( 1 , 3 )&1<<4)?0:1 ;

left_top = (GetOIAInput ( 1 , 4 )&1<<7)?0:1 ;
right_top = (GetOIAInput ( 1 , 4 )&1<<6)?0:1 ;
left_trigger = (GetOIAInput ( 1 , 4 )&1<<5)?0:1 ;
right_trigger = (GetOIAInput ( 1 , 4 )&1<<4)?0:1 ;


I'm not sure how to properly define this so the compiler does barf but if you can do it in C you can do it in easyC

edit: I got it to work I think...

Click on the projects tab and paste:

#define BUTTON_5 ((~GetOIAInput ( 1 , 3 ) &0x80)!=0) // same as p1_wheel

Into UserInclude.h

Also the Xbox controller itself isn't the best unit the thumbsticks stick and don't recenter well. The Logictech "PS2" like controller works better.
