It looks that the format is in little endian.

Is there a way to configure it to big endian?

Yes, the PSoC 5 uses the GCC compiler and it is in little endian format. To change the endianess just add the custom flag "-mbig-endian" in the command line section provided in the compiler options of the build settings as shown below:

You can find the list of custom flags available here: https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html

However, please note that our architecture supports only little endian format and changing it might prove disastrous for your project.

There is an ARM machine instruction to set/change the endianess. But I am sure that neither C-compiler nor the components will work after a change. What is the reason for your question, what do you need to perform?

Thanks Bob.

I am using this data in the communication with other device.

Just wanted to know if there is a standard way to cahnge, befoe I make the conversion myself.
