Right. I mis-read your post

Because of the release of Nleash and the ability to use Ndless on Touchpad Nspires, do we have the keypad mappings (or a new common.h file) for the touchpad.  In this case, we could just compile four versions of our programs (Non CAS Clickpad, CAS Clickpad, Non CAS Touchpad, CAS Touchpad) to be used on any Nspire.

Here are some text output routines. The character map is courtesy of Armael on United TI, and the routines are inspired by his, too. Right now, all I have is a function akin to TI-BASIC's text() function - pass it a string and some coordinates, and it will draw it to the designated screen buffer.
There used to be more, but no program loader -> no static variables -> a real console becomes incredibly unwieldy I thought about passing pointers to the cursor coordinates to the functions, but that's a bit too unwieldy.

File descriptions:
charmap_8x12.h: the character map.
screen.h: contains functions putChar and drawStr.
stdarg.h: variable-length argument list header.
string.h: some string functions

Do we have entry points for vsprintf()? That would make writing a printf() so much easier.

Enjoy! And remember, this is a very in-progress set of routines, so don't use them for anything fancy.

Edited the first post and skeleton.zip to include the new text routines. I've found them rather useful, despite their limited abilities, so they've been integrated into skeleton.zip for the moment.
bsl and I (on United-TI) have found how to list files. This seems useful, so dirlist.h has been placed into skeleton.zip as well.
The syntax for dirlist() is:
int dirlist(char* path, char* pattern, char** result)
path: the folder you are looking in, e.g. "/documents/examples"
pattern: a search pattern, e.g. "*.tns"
result: a pointer to a char* (i.e. a list of strings) that will store the resulting filenames

return value: the number of files found


That is a good idea. I presume Ndless supports such things at the moment, despite the lack of a program loader?

Nope, the skeleton supports the arm-elf versions only. If you can modify it to work with 4.5.0 and post it, I'll attach it to the OP (I don't have a Windows machine to test on, so I can't update it).

Updated the OP with a new skeleton.zip. filesize() should be useful for level loaders and the like.
apcalc, have you tested whether changing the Makefile works yet?

Easy ASCII input:

struct event {
unsigned int timestamp;
unsigned short type;
unsigned short ascii;
unsigned int key;
unsigned int unknown[3];
unsigned int control;
};

#ifdef CAS
#define get_event (_oscall(int, 0x100CBF78, struct event *))
#else
#define get_event (_oscall(int, 0x100CBF44, struct event *))
#endif

int getch() {
struct event event;
do {
get_event(&event);
} while (event.type != 8 || event.ascii == 0);
return event.ascii;
}
