(...) D'oh... I'm posting this because I'm sure I'm not the only one who missed this: I didn't realize there's a drop-down when BricxCC starts up, to select "Swan" instead of "RCX" when making the first handshake with the brick. After doing that, it (...) (12 years ago, 19-Jul-12, to lugnet.robotics.rcx)

(...) (snip) (...) BrixCC doesn't recognize "wait1Msec", and when I try to download a program with it, it just gives me an error. That's kind of what I was getting at with the motor power stuff; I can tell the RCX can handle more motor powers, but (...) (12 years ago, 18-Jul-12, to lugnet.robotics.rcx)

| | Faster Firmware/Motor Control
|
|
Hi all, One of the common ways I like to control the speed of a gearmotor (in NQC) is by introducing a loop, for example, like this: while(true) { OnFwd(motor); Wait(a); Off(motor); Wait(b); } I often do this as a motor approaches a setpoint (say an (...)

(...) Initially (at least) the Pi comes without a case, so I expect it is just a matter of building around it so it doesn't rattle too much. I haven't received mine yet, but I'll take a moment to see how well a pure LEGO case can work. It feels a (...) (13 years ago, 13-Apr-12, to lugnet.robotics, FTX)
