There are no new unread posts for this topic.   I notice that the sonar sensor returns distance in inches, is it possible to use metric instead? I live in the US, but I just find so many things easier to do in metric! I've been poking around, searching forums and sample code but haven't run across anything yet. Thanks. Is it possible to use metric?

There are no new unread posts for this topic.   This is very peculiar. Notice that Fingers where f is an "int" type. This will give me 0 x,y,z reading every other read/send. Then, I put in the constant instead in the "read.." and "send..", things will start working again. So, I have to do a silly workaround. Although there is a workaround, the reference of Fingers .s should work though. I2C bug?

But it gives me errors at compilation. Isn't bitfield supported by RobotC? Another question : how to know the size of memory used by variables (if I am near the 15k !!) and even by code? thanx, Bichon. bitfield and size optimization
