Basically I was trying to cast an int to a char</p> <p>int a = 5;<br /> char b[] = char(a);<br /> char c[] = "String 1";<br /> char d[] = "String 2";</p> <p>Serial1.print(b+c);<br /> Serial1.print(c+d);</p> <p>c + d worked b + c did not.</p> <p>I will try out the methods you guys suggested when I get home from work. Thanks again for the help. </p> http://forums.leaflabs.com/topic.php?id=9142#post-20225 Mon, 08 Oct 2012 11:05:27 +0000 gbulmer 20225@http://forums.leaflabs.com/ <p>If the requirement is to 'print' a float or double into an array of characters, then their is the Open Source newlib, which has a set of functions which do those conversions<br /> <a href="http://sourceware.org/newlib/" rel="nofollow">http://sourceware.org/newlib/</a></p> <p>If you want to do it yourself, there is a <code>printFloat</code> member function in Print.cpp which converst a double to a characters and prints them. It would give you a template; replace the use of <code>print()</code> with storing the character into the <code>char</code> array. </p> http://forums.leaflabs.com/topic.php?id=9142#post-20212 Sun, 07 Oct 2012 20:57:34 +0000 crenn 20212@http://forums.leaflabs.com/ <p>I'm going to go on a limb here and suggest you want a string stating the value of a float or integer rather than just a character representing the float/integer value.</p> <p>There is 2 methods I can suggest to fixing this issue, making your own function to convert it to a string or using sprintf. </p> http://forums.leaflabs.com/topic.php?id=9142#post-20208 Sun, 07 Oct 2012 17:27:08 +0000 gbulmer 20208@http://forums.leaflabs.com/ <p>Ron - what have you tried?</p> <p>When you write "cant figure out how to covert or cast a float/double/int to char and concatenate it to another char." What are you trying to do?<br /> Usually it is print a float/double/int as an array of characters, but you appear to be trying to convert a float/double/int to a single char. Would you give some examples of what you have, and what the value should look like. </p> http://forums.leaflabs.com/topic.php?id=9142#post-20207 Sun, 07 Oct 2012 16:26:40 +0000 rons 20207@http://forums.leaflabs.com/ <p>So I just got my maple board and I have been trying to send sensor data to a serial lcd (ezLCD301). But I cant figure out how to covert or cast a float/double/int to char and concatenate it to another char. Ive tried a bunch of things but nothing works.</p> <p>Any help would be appreciated.</p> <p>Thanks<br /> Ron </p>
