(...) That's where your completely wrong. I can see the error, calls to motor power should be set out like this motorPower128(1) = MyVariableName; in this example the constant "1" means set the power to output B to the value specified by (...) (19 years ago, 20-Jul-05, to lugnet.robotics.rcx.nqc)

(...) * Maybe I wasn't too clear, but really there isn't much to say: it is the SetMotorPower128 command that causes the error. * Another question is: why costants MTR_A or MTR_B don't work at all? Here's the code(all the code): task main{ (...) (19 years ago, 20-Jul-05, to lugnet.robotics.rcx.nqc)

Hi. I've installed new NQC and BRICXcc to test new functions in fast firmware by Dick Swan. I wanted to see if the new 1/1000th second resolution could let me drive a servo. When I try to use the SetMotorPower128 command, compiler is ok, downloading (...) (19 years ago, 19-Jul-05, to lugnet.robotics.rcx.nqc)

(...) Hi John I've fixed the problem. I tracked it down by commenting out parts of my program. Luckily I started on the function containing the problem So I found it very quickly. Solving the problem took longer though. As you can see below I've (...) (19 years ago, 16-Jul-05, to lugnet.robotics.rcx.nqc)

I also have trouble believing variations in parts (except the motors themselves) will cause this much difference. Ralph (19 years ago, 14-Jul-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)
