Here you can post examples, fixes, etc for the
NXC Help File. Hopefully, John Hansen will update the help file to accommodate your improvements.
For example,
ex_SetVMRunState.nxc, contains the following at the moment this post was written:
Not too helpful, eh? Try your hand at improving it. This is a little better:
Code: Select all
SetVMRunState(UI_VM_IDLE); // stopped
*Disclaimer: I don't really understand what this code does.
There's many of these types of "examples" ** out there:
Could be improved to:
Code: Select all
float a = ceil(3.01);
// a == 4.0
float b = ceil(3.14);
// b == 4.0
float c = ceil(3.99);
// c == 4.0
float d = ceil(4.0);
// d == 4.0
** Not critisising anyone, least of all John.

Switch the descriptions of
UI_VM_RESET1 and
UI_VM_RESET2.

I will certainly take these contributions and use them to improve the NXC help. Thanks!
It might also be helpful to email me replacement sample code files (e.g., ex_FUNCTIONNAME.nxc) directly or post them as attachments that I can simply download and rename from .txt to .nxc or something like that.

[This post provides an example, and also defines the format for future posts of example files.]

Notes:
This program example [and variations] can be used in more than one API call example.
[Optional code snippet.]
ex_SetLongAbort.nxc:
Code: Select all
task main()
{
// Set exit button to end program only if it is pressed for longer than 2 seconds
#ifdef __ENHANCED_FIRMWARE
SetLongAbort(true);
// is equivalent to
SetAbortFlag(BTNSTATE_LONG_PRESSED_EV);
#endif
while(true)
{
ClearScreen();
// Display on NXT Screen: "Press the exit button longer (for 2 seconds) to exit"
TextOut(0, LCD_LINE1, "Press the exit", 0);
TextOut(0, LCD_LINE2, "button longer", 0);
TextOut(0, LCD_LINE3, "(for 2 seconds)", 0);
TextOut(0, LCD_LINE4, "to exit.", 0);
// Display number of times the user has pressed the exit button (for less than 2 seconds)
NumOut(0, LCD_LINE8, ButtonPressCount(BTNEXIT), 0);
// Wait until user presses and releases exit button before continuing loop
while(!(ButtonPressed(BTNEXIT, 0)));
while(ButtonPressed(BTNEXIT, 0));
}
}
