 | | 8479 Code Pilot Barcode Analysis and Code Sheet
|
|
Dr. Soubhi Sabbagh contacted me recently to get information on Code Pilot, and collecting various sources he was able to analyse and create a PDF code sheet. " So, I decided to study the bar code algorithm and I co-operated with www.dlsoft.com until (...) (17 years ago, 5-Jan-08, to lugnet.robotics.codepilot, lugnet.technic)

Hi Ross, (...) it should be possible to use RS-485 as a bus, i.e. connect several NXTs with one cable. You need to make the cable yourself, though, and you may need some termination on the ends. Jürgen (17 years ago, 4-Jan-08, to lugnet.robotics.nxt)

(...) Thanks John. I agree that from the electrical point of view, just connecting one port 4 to another port 4 should just work with no hardware other than the cable (for short lengths, like the cables that come with the NXT). For longer cables, a (...) (17 years ago, 5-Jan-08, to lugnet.robotics.nxt)

(...) Two. Input port #4 fills up pretty quick. Should give a nice performance boost over BT though. (17 years ago, 4-Jan-08, to lugnet.robotics.nxt)

I'm having a book signing this month for my new book The Unofficial LEGO MINDSTORMS NXT Inventor's Guide (No Starch Press), and I decided to officially announce the book here on LUGNET and invite everyone who lives in the Round Rock, Texas area to (...)

(...) 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.

(...) Remove the #include "NXCDefs.h" line since recent versions of the compiler do not require that you explicitly include this file. Make sure you are running the latest BricxCC and NBC/NXC compiler. The lastest version of the compiler is (...) (17 years ago, 30-Dec-07, to lugnet.robotics.nxt)
