ECE 4510/5530 MICROCONTROLLER APPLICATIONS
Fall 2008
Prelab Assignment for Lab Eleven
The designated CAN Module is CAN1. The CPU clock rate is 8MHz.
1. Draw a detailed cable hookup diagram for Task One. It should include all
relevant Header pin numbers.
2. Develop a C program for Task One. The Baud rate should be set to 500Kbs.
Select the Oscillator Clock for the MSCAN clock source. Study Section 4.3.2 of
the MSCAN Data Sheets carefully to make your decision on the parameter
values for the Bit-Time and the Prescaler. Set up four 16-bit acceptance filters,
however, the Lab TA will define the ID and filter values. Work with a single
CAN transmit buffer.
The memory locations for the transmit and receive buffer arrays should be
0x1020 and 0x1060, respectively. The receive buffer area should be initialized to
all zeroes. The message to be transmitted should be made up of 32 characters.
It is to be terminated by a 0x00 (EOS) character (not included in the count) that
will not be transmitted. The program should keep on receiving and transmitting
messages on the CAN Bus. You should use both the MSCAN1 Transmit and
Receive Interrupts, respectively, to synchronize the CPU and the CAN1 Module.
