Process: Using 2 CAN peripheral CAN1 and CAN2 to test CAN operation. This example supports all kind of identifier: FullCAN, explicit or group format. Both CAN1 and CAN2 are set baudrate at 125KHz. First, settup AF look-up table with 5 sections: - 6 entries for FullCAN section - 6 entries for Standard Frame Format (SFF) section - 6 entries for Group Standard Frame Format (SFF_GRP) section - 6 entries for Extended Frame Format (EFF) section - 6 entries for Group Extended Frame Format (EFF_GRP) section Initialize 10 messages: - 1st message with 11-bit ID which exit in AF Look-up Table in FullCAN Section - 2nd message with 11-bit ID which not exit in AF Look-up Table - 3th message with 11-bit ID which exit in AF Look-up Table in SFF Section - 4th message with 11-bit ID which not exit in AF Look-up Table - 5th message with 11-bit ID which exit in AF Look-up Table in Group SFF Section - 6th message with 11-bit ID which not exit in AF Look-up Table - 7th message with 29-bit ID which exit in AF Look-up Table in EFF Section - 8th message with 29-bit ID which not exit in AF Look-up Table - 9th message with 29-bit ID which exit in AF Look-up Table in Group of EFF Section - 10th message with 29-bit ID which not exit in AF Look-up Table Then, send 10 messages from CAN1 to CAN2, whenever CAN2 receive message that has ID exit in its AFLUT, CAN receive interrupt occurs, CAN interrupt service routine "CAN_IRQHandler" will be invoked to receive message and save it in array "AFRxMsg[]". In this case, message 1,3,5,7,9 will be received. After that, "CAN_ChangeAFTable" function will be called to load and remove entries in AFLUT in such a way as to receive messages 2,4,6,9,10 instead of 1,3,5,7,9. Re-send 10 messages and re-received messages to check if AFLUT operation correct or not. Open serial display window to observe CAN transfer processing. @Directory contents: \EWARM: includes EWARM (IAR) project and configuration files \Keil: includes RVMDK (Keil)project and configuration files lpc17xx_libcfg.h: Library configuration file - include needed driver library for this example makefile: Example's makefile (to build with GNU toolchain) can_test_aflut.c: Main program @How to run: Hardware configuration: This example was tested only on: Keil MCB1700 with LPC1768 vers.1 These jumpers must be configured as following: - VDDIO: ON - VDDREGS: ON - VBUS: ON - Remain jumpers: OFF CAN connection: - CAN1-Pin2 connects to CAN2-Pin2 (CAN-L) - CAN1-Pin7 connects to CAN2-Pin7 (CAN-H) Serial display configuration:(e.g: TeraTerm, Hyperterminal, Flash Magic...) 115200bps 8 data bit No parity 1 stop bit No flow control Running mode: This example can run on RAM/ROM mode. Note: If want to burn hex file to board by using Flash Magic, these jumpers need to be connected: - MCB1700 with LPC1768 ver.1: + RST: ON + ISP: ON - IAR LPC1768 KickStart vers.A: + RST_E: ON + ISP_E: ON (Please reference "LPC1000 Software Development Toolchain" - chapter 4 "Creating and working with LPC1000CMSIS project" for more information) Step to run: - Step 1: Build example. - Step 2: Burn hex file into board (if run on ROM mode) - Step 3: Connect UART0 on this board to COM port on your computer - Step 4: Configure hardware and serial display as above instruction - Step 5: Run example: - Press "1" to initialize message and AFLUT - Press "2" to start CAN operation - Press "3" to display received messages - Press "4" to change AFLUT - Press "5" to re-send message - Press "6" to display received messages (Pls see "LPC17xx Example Description" document - chapter "Examples > CAN > CAN_test_aflut" for more details) @Tip: - Open \EWARM\*.eww project file to run example on IAR - Open \RVMDK\*.uvproj project file to run example on Keil
