This is the public header file of the C++ CANopen application library.
lely::canopen::detail::IsCanopenSame
bool IsCanopenSame(uint16_t t1, uint16_t t2)
Returns true if the CANopen data types t1 and t2 map to the same C++ type, and false if not.

lely::canopen::detail::IsCanopenArray
If T is one of the CANopen array types, provides the member constant value equal to true.
Definition: type_traits.hpp:50
lely::canopen::detail::IsCanopenBasic
If T is one of the CANopen basic types, provides the member constant value equal to true.
Definition: type_traits.hpp:43
lely::canopen::detail::IsCanopenType
If T is one of the CANopen basic or array types, provides the member constant value equal to true.
Definition: type_traits.hpp:59
type.h
This header file is part of the CANopen library; it contains the CANopen type definitions.
CO_DEFTYPE_DOMAIN
#define CO_DEFTYPE_DOMAIN
The data type (and object index) of an arbitrary large block of data.
Definition: type.h:77
CO_DEFTYPE_OCTET_STRING
#define CO_DEFTYPE_OCTET_STRING
The data type (and object index) of an array of octets.
