Hi,

With the latest copy of RobotC and the Cortex firmware, I seem to be unable to use the digital ports 9 and 10 on the microcontroller. When I plugged in several different sonars, input first and then output, the debugger would report that the sonar reading was -1, even when flat panels were placed in front of it. Does anyone else have this problem?

Thanks for pointing this out. We spent the whole morning testing this and confirmed it. We are working on a fix.
