Detailed Description

Target specific basic definitions and data types according to Misra C specification.

Must be defined in the CO_driver_target.h file.

Depending on processor or compiler architecture, one of the two macros must be defined: CO_LITTLE_ENDIAN or CO_BIG_ENDIAN. CANopen itself is little endian.

Basic data types may be specified differently on different architectures. Usually true and false are defined in <stdbool.h>, NULL is defined in <stddef.h>, int8_t to uint64_t are defined in <stdint.h>.
