Hi Dear All,

Because many people like me are searching for an implementation of the CANOpen on the LPC microcontrollers, I have decide to start a project to implement the CANOpen layer, with your help, using LPCOpen (periph_can example) and the following open source CANOpen Node: GitHub - CANopenNode/CANopenNode: CANopen stack base.

 

First of all, I have never use CAN before. I am working to well understand the LPCOpen CAN controller example.

My First question is related to the Acceptance Filter LookUp Table: how can the following code (from LPCOpen)

CAN_STD_ID_ENTRY_T FullCANSection[] = {   {CAN_CTRL_NO, 0, 0x03},   {CAN_CTRL_NO, 0, 0x05},   {CAN_CTRL_NO, 0, 0x07},   {CAN_CTRL_NO, 0, 0x09}, };

accept the followings id 0x03, 0x04, 0x07, 0x09 (regarding to the readme and confirmed by CAN analyzer)?

What is the difference between Full CAN Section, Individual Standard ID Section & Standard ID Range Section?

 

Thank you
