 | | Electronics Prototyping with the LEGO NXT

|
Hi Folks, I've been exploring various ways to use the LEGO NXT in enhancing electronics through Robotics and I've just posted a short video on the subject matter at my blog (URL). I'll be writing an eZCIRCUITs application note on the construction (...) (17 years ago, 5-Sep-07, to lugnet.robotics.nxt)

(...) I wasn't aware of this firmware limitation. I could not duplicate it when using the ROBOTC firmware. I've done three different test runs of 500K messages each with perfect results each time. Each test run used a different sensor. The delay (...) (17 years ago, 5-Sep-07, to lugnet.robotics.nxt)

(...) Nearly all of the speed test numbers on Steve's page are wrong. That's because Steve's loop boils down to "how fast can you reliably read the LEGO Ultrasonic Sensor". You can't reliably read a value from that device faster than about once (...) (17 years ago, 2-Sep-07, to lugnet.robotics.nxt)

My bad. When I fiddled with the pbLua code I forgot to turn on the motors and neglected to change the Motor A speed. So when you ran the program, the motors didn't move.

Hi, do you think pbLua needs an IDE/GUI for development ? Normaly, pbLua just needs a working terminal emulation for development... BUT, I've learned from Lego-NXT-Users: that's not enough, NBC/NXC has "bricxcc" !!! pbLua has more than ONE GUI for (...) (17 years ago, 31-Aug-07, to lugnet.robotics.nxt)
