After doing some experiment, I found that the COSMIC compiler supports the BIG endian approach for STM8S103F3 as default mode. Can it support Little Endian approach ?

Why do you care? If you had external peripherals on a bus I could understand but the STM8S103F3 doesn't have an external bus.

If you need to send/receive data in big-endian order

to perform the conversion. That's what people have been doing on PC's (80x86's are little-endian) for decades.

Hello,

in addition to the considerations above, it is interesting to underline that, for a micro like stm8, who is capable of multibyte operations (ld.w), the endianness is forced by the micro itself (-> does not depend on the compiler): STM8 is little endian.
