Thank you all for the replies, i'll try each method and see which one fits best (probably the lookup table method). The sole reason I can't just lcd.print the codes is that the lcd has 3 seperate screens, they get cycled through every 3 seconds, lcd.print'ing all the variables would kind of wreck this system so i've got a queue of what is displayed instead.</p> <p>Thanks guys! </p> http://forums.leaflabs.com/topic.php?id=10445#post-23945 Wed, 27 Mar 2013 14:07:50 +0000 ventosus 23945@http://forums.leaflabs.com/ <p>You could also use a lookup table, gives much "nicer" code, IMHO</p> <p><code><br /> const char *timbre_lookup [] = {<br /> "sine wave",<br /> "square wave",<br /> "sawtooth wave",<br /> ...<br /> };<br /> </code></p> <p>and then just look your value up in the code</p> <p><code><br /> char *timbre = timbre_lookup[timbreread];<br /> </code> </p> http://forums.leaflabs.com/topic.php?id=10445#post-23943 Wed, 27 Mar 2013 11:35:32 +0000 mlundinse 23943@http://forums.leaflabs.com/ <p>You can simply declare timbre as a pointer to a char array.</p> <p>char * timbre;</p> <p>Regards,<br /> Magnus </p> http://forums.leaflabs.com/topic.php?id=10445#post-23942 Wed, 27 Mar 2013 11:25:49 +0000 siy 23942@http://forums.leaflabs.com/ <p>Variable 'timbre' in your code should be pointer to char, not char. </p> http://forums.leaflabs.com/topic.php?id=10445#post-23940 Wed, 27 Mar 2013 11:06:00 +0000 bubulindo 23940@http://forums.leaflabs.com/ <p>Using strings... </p> <p>Instead of saving this to a variable, why doing something like lcd.print("XXXXX wave"); ? </p> http://forums.leaflabs.com/topic.php?id=10445#post-23938 Wed, 27 Mar 2013 10:18:49 +0000 pyrohaz 23938@http://forums.leaflabs.com/ <p>Hey guys, I wrote a sketch on my arduino using a switch statement to determine what will be written to an LCD, it looks like:</p> <p>switch(timbreread){<br /> case 0:<br /> timbre = "sine wave";<br /> break;<br /> case 1:<br /> timbre = "square wave";<br /> break;<br /> case 2:<br /> timbre = "sawtooth wave";<br /> break;<br /> case 3:<br /> timbre = "triangle wave";<br /> break;<br /> case 4:<br /> timbre = "random wave 1";<br /> break;<br /> case 5:<br /> timbre = "random wave 2";<br /> break;<br /> case 6:<br /> timbre = "random wave 3";<br /> break;<br /> }</p> <p>The variable timbreread is merely a number between 0 and 6 to select the correct timbre. The value timbre is stored as a String. Since I don't get strings on maple, how can I implement this snippet of code? I've tried using char and it just doesn't seem to work.</p> <p>Thanks,<br /> Harris </p>
