 | | Rotation sensor bug found (maybe!)
|
|
I think I might have found a bug in the ds_rotation_handler (direct-sensor.c). The problem arises when the STATE_0_VALUE is checked using the IN_RANGE macro. As STATE_0_VALUE is 1023U<<6, which is about the max value for an unsigned, adding to it (...) (25 years ago, 17-Apr-99, to lugnet.robotics.rcx.legos)

As far as reserving an address for IPC that would be fine. We could reserve 00000b for IPC and (...) (25 years ago, 17-Apr-99, to lugnet.robotics.rcx.legos)
