Two Arduinos in serial connection

Former Member

Hi There

 

I want to send over a large integer over from one Arduino to the other through a serial connection. I know how to do this with a char, but a number like 234 and still having it as an integer on the Arduino send to, confuses me a bit. If someone could assist me with the code to do it, I'll appreciate it!

 

Thanks

    Hi Andre

     

    If you have read the numeric characters - 234 in your question - , into a character array - call it numChar, then you can use the C++ standard library function atoi() to convert to an Integer - numInt = atoi(numChar);

     

    If the numeric characters have been read into a String Object, you can copy them to a character array using the standard Arduino function string.to CharArray() and then use atoi().


    I struggled with this problem myself. Hope it helps
