Binary string from FG to Arduino

[felipetallabs]

Hi

I am sending data from FG to Arduino in binary, using:

<binary_mode>true</binary_mode>
<byte_order>host</byte_order>

my question is, once it arrives in arduino, how to I convert it to decimal?

Thanks

By decimal, do you mean value with float precision?
Have you checked section Binary protocol parameters at http://wiki.flightgear.org/Generic_protocol?

If you do it binary I guess you must read 8 bytes and copy/shift into the variable, but I am not sure about any other need to convert the data. Perhaps you can find more info here: http://wiki.flightgear.org/Howto:Parsing_binary_data_received_via_UDP_in_C?

Hi

Thanks for the response

I guess my question is:

My XML protocol in FG is sending constant values from a node, let's say one of the values is 0.379, for example, then I receive this number in Arduino as a Binary string, does the Arduino IDE convert this number back to float automatically? Or I have to do this myself in order to use this value in my protocol?

Thanks again

Hi felipetallabs, I think (from my limited understanding) you'll have to code the arduino to convert the binary, using a non-binary mode might make things easier in the arduino code unless you're creating a very large, complex system.
