I recently updated the test release of BricxCC with additional support for the
NXT. In conjunction with the latest beta of NBC you can now write programs that
target the standard NXT firmware in three different text-based programming
languages. NBC continues to grow its library of API macros which significantly
simplify writing programs. Playing a file, for instance, is as simple as
calling the PlayFile macro function like so:
PlayFile('mysound.rso') // play a sound file
or
PlayFile('mymelody.rmd') ; play a melody file
BricxCC now includes support for a very simple 5-line declarative programming
language called NPG which lets you write, compile, download, and run simple NXT
Programs using a text language. The commands that can be used in an NPG 5-line
program are EmptyMove, Forward, ForwardFive, BackLeftTwo, TurnLeft, TurnLeftTwo,
BackRight, TurnRight, TurnRightTwo, BackLeft, PlayToneOne, PlayToneTwo,
Backward, BackwardFive, BackRightTwo, EmptyWait, WaitForLight, WaitForObject,
WaitForSound, WaitForTouch, WaitTwoSeconds, WaitFiveSeconds, WaitTenSeconds,
WaitForDark, EndLoop, and EndStop. RPG programs require the RPGReader.sys
executable to be installed on the NXT. The original RPGReader.sys NXT program
is ~14.3kb in size. A smaller RPGReader.sys replacement can be downloaded from
the NBC samples page. This replacement implements a very similar functionality
as exists in the original RPGReader.sys but it is only ~2.5kb in size. The NXT
Explorer in BricxCC can execute and stop RPG programs now as well.
BricxCC also now supports a very early test release of the NXC programming
language. NXC is built into the NBC compiler. It is extremely limited at
present, but it will develop rapidly over the next few weeks. Here are a few
sample NXC programs:
#include "NXCDefs.h"
int move_time, turn_time;
task main()
{
while(TRUE)
{
move_time = 6000;
turn_time = 4000;
// move_time = Random(600);
// turn_time = Random(400);
OnFwd(OUT_AC, 75);
Wait(move_time);
OnRev(OUT_A, 75);
Wait(turn_time);
}
}
-----------------------------------------------------
#include "NXCDefs.h"
task main()
{
OnFwd(OUT_A, 75);
OnFwd(OUT_B, 75);
Wait(4000);
OnRev(OUT_AB, 75);
Wait(4000);
Off(OUT_AB);
}
----------------------------------------------------
int x, y, z;
bool p, d, q;
mutex myMutex;
char c;
unsigned short s;
sub Weird()
{
Write(z);
}
task main()
{
x=-130;
// z = 10;
z = 40+(10-16)/3;
while (x < 10)
{
/*
z += 2;
*/
Weird();
z -= 4;
if (0) { continue; }
Wait(500);
x++;
}
Cls();
s = 500;
Wait(s+500);
for (z=0; z < 10; z++)
{
Weird();
if (z < 0) {
break;
}
Wait(500);
}
Wait(3000);
}
BricxCC also has improved support for the NXT via its main Watch window and the
NXT Explorer window now supports dropping files from any explorer window on the
NXT pane.

| John, THANK YOU so much for this. I cant wait to have a few minuites to myself (sans wife/kids/work) so I can download and play. if I grok your C code fragments for NXT via BrickCC, then I just might have a programmed robot yet. Thank you for your (...) (17 years ago, 24-Nov-06, to lugnet.robotics)
