Has anyone figured out how to reliably convert doubles to strings (String or char*) on the Neo? Mine locks up when I try to run the following code: Code: double x = 1234.56; String s = String(x, 2); snprintf doesn't like "%f"s either, so I'm at a loss here.
I also saw this problem on neo, see here The solution that i use for the moment is to send only int from M4 to A9 and convert it in float A9 side with c++ ...
Thanks, I didn't find that thread when I searched for the problem. I'm actually trying to write values to a file, not send them over serial, otherwise I would try your solution. I'll move on over to your thread now...
