Data

The class CO_PARA is defined within co_para.h and is responsible for storing and restoring the right CANopen parameter groups in dependency to the NMT reset type. The following data members are in this class:

Data Member	Type	Description
Size	uint32_t	size of parameter memory block
Start	uint8_t*	pointer to parameter memory block
Default	uint8_t*	pointer to default parameter block
Type	CO_NMT_RESET	parameter group reset type
Ident	uintptr_t*	pointer to user identification code
Value	uint32_t	value, when reading this parameter group

Functions

The following table describes the API functions of the CANopen parameter module. These functions are implemented within the source file: co_para.c/h
