(...) Cool! I wonder if you could daisy-chain NXTs using this technique, and if so, how many you could connect? ROSCO (17 years ago, 4-Jan-08, to lugnet.robotics.nxt)

| | Hi-speed port communication
|
|
I've been getting a number of emails from some people who want to know how to use the hi-speed RS-485 port 4 functionality in the NXT using the standard firmware. With John Barnes' help I now know how to get it to work correctly. Here is a simple (...) (17 years ago, 4-Jan-08, to lugnet.robotics.nxt)

(...) Indeed, this 180mA limitation is the one of the 4.3V power supply, that feeds the sensors and the motor position encoders. The motors themselves can receive a much higher current, limited by their own thermal protection and by the maximum (...) (17 years ago, 31-Dec-07, to lugnet.robotics.nxt)

| | NXT iterate files
|
|
I wrote some NXC code that runs on the enhanced NBC/NXC firmware. It demonstrates how to iterate files on the filesystem. Let me know if you have any questions.

Dear all, For those interested, I have been exploring the use of rapid prototyping technology in building new parts for the NXT. I attempted to build a propeller brick in combination with a more powerful motor. Read my results on (...) (17 years ago, 30-Dec-07, to lugnet.robotics.nxt)

I've tried to install Bricx and NXC but when I try to compile a simple program I get an error like "Unable to find include file: "NXCDefs.h".
