/* Code by Parth Patel, Penn Electric Racing 2014, 9/23/2014 This library provides an easy to use, buffered, hardware-filtered CAN interface for high performance CAN applications. Provides automatic reception of messages via CAN RX interrupt into a rx ring buffer. Provides automatic transmission of messages via CAN TX interrupt. @File CAN_Filter_LUT.h: Contains the formatted lookup tables to program the onboard CAN acceptance filters */ #ifndef _FILE_CAN_FILTER_LUT_H #define _FILE_CAN_FILTER_LUT_H #define STDMASK 0x7FF #define EXTMASK 0x1FFFFFFF // These arrays defines the CAN Controller Acceptance Filter Lookup Table. // Follow notes below or else the chip's behaviour will be undefined // MAX SIZE PERMITTED = 512 32bit ints total across all tables // Note that AF_LUT_SEI is 16bit, divide #entries by 2 for this one // Note that AF_LUT_EIR is 64bit, multipy #entries by 2 for this one const uint16_t AF_LUT_SEI[] = { // !!
