<h1> How to make a program against ticables library </h1>
<hr>
<pre> <em> </em></pre>
You will find in the <i>test</i> folder of the library source archive a
test/example program which uses this lib.<br>
Below is a light version (most error management has been removed) of this
program to make it clearer:
<pre># include <stdio.h>
# include <string.h>
# include <glib.h>
# include <ticables.h>
static void print_lc_error(int errnum)
{
char *msg;
ticables_error_get(errnum, &msg);
fprintf(stderr, "Link cable error (code %i)...\n<<%s>>\n",
errnum, msg);
g_free(msg);
}
int main(int argc, char **argv)
{
CableHandle *handle;
int err, i;
uint8_t buf[4];
// init lib
ticables_library_init();
// set cable
handle = ticables_handle_new(CABLE_SLV, PORT_1);
if(handle == NULL)
return -1;
ticables_options_set_timeout(handle, 15);
ticables_options_set_delay(handle, 10);
ticables_handle_show(handle);
// open cable
err = ticables_cable_open(handle);
if(err) print_lc_error(err);
if(err) return -1;
// do a simple test with a TI89/92+ calculator
buf[0] = 0x08; buf[1] = 0x68; buf[2] = 0x00; buf[3] = 0x00; // RDY
err = ticables_cable_send(handle, buf, 4);
if(err) print_lc_error(err);
// display answer
memset(buf, 0xff, 4);
err = ticables_cable_recv(handle, buf, 4);
if(err) print_lc_error(err);
for(i = 0; i < 4; i++)
printf("%02x ", buf[i]);
printf("\n");
// close cable
ticables_cable_close(handle);
// release handle
ticables_handle_del(handle);
// exit lib
ticables_library_exit();
return 0;
}
</pre>
That's all !<br><br>
<strong>NOTE</strong>: for this example to work, you probably have to add compiler options related to the include path and library path, e.g.
<pre>gcc -I/usr/include/tilp2 -Os -g -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -Wall -W ticables.c -o ticables -lglib-2.0 -lticables2</pre>
or better
<pre>gcc -Os -g -Wall -W `pkg-config --cflags --libs ticables2` ticables.c -o ticables</pre>
