| | NQC tutorial available

In my opinion NQC is the easiest way to program the Lego Robots. But people that never programmed before seem to think it is difficult (maybe because it sounds like C). So I decided to write an extensive tutorial on how to use NQC. The tutorial does (...) (26 years ago, 29-Mar-99, to lugnet.robotics.rcx.nqc, lugnet.robotics)

I just put a Win32/i386 port of netpbm on my ftp site (ftp://ftp.phred.org...bm-e.zip). Very little documentation, but it should be easier then uploading and downloading files from a unix account.

You might find netpbm to be helpful. It contains tools to convert the PBM (monochrome), PGM (grayscale) and PPM (color) formats into just about anything. P?M are file format for images which is easy to generate. In its simplest form PGM (what you'd (...) (26 years ago, 22-Mar-99, to lugnet.robotics.rcx.nqc)

I noticed that the byte code command to implement the SetClock(hrs,min) wasn't implemented in the nqc.h file.

(...) There's a bytecode (0x30) that instructs the RCX to send the battery voltage as a response over the IR. That's what NQC and Mindstorms use to read the battery voltage.
