Having downloaded a copy of swan_test.zip which contains the latest test release
of BricxCC and NQC you can use nearly all the new and enhanced features in the
Swan firmware. You can view the "official" API built into NQC by executing the
following command line:
nqc -api > api.nqh
This file can be loaded into BricxCC and you can use the Procedure List and the
Code Explorer to browse through the file looking at all the various constants
and functions. Most of the new Swan API is near the very end of the file within
a #if defined(__SWAN) section.
The 1 ms timer routines are defined as follows:
#define MSTimer(n) @(0x160000 + (n))
__nolist void ResetMSTimer(const int n) { Set(MSTimer(n), 0); }
__nolist void WaitMS(const int &v) { asm { 0x47, $v : __ASM_SRC_EXT}; }
So if you want to use the 10 millisecond wait you use Wait(n) and if you want to
use the 1 millisecond wait you use WaitMS(n). If you want to read the 10ms
timer you use FastTimer(n). If you want to read the 100ms timer you use
Timer(n). If you want to read the 1ms timer you use MSTimer(n).
task main()
{
int x = 1;
for (x = 0; x < 100; x++)
{
SetUserDisplay(x, DISPLAY_USER);
WaitMS(1000);
}
}
This short program will update the display with the value of variable x one time
each second.

| Okay, okay, bad form responding to my own post. I got the new firmware on my RCX, downloaded the latest version of BricxCC, and NQC. But I can't figure out how to use this SetUserDisplay command? I want to show a variable on the display. I have no (...) (20 years ago, 6-Feb-05, to lugnet.robotics.rcx.nqc)
