CAN

Readme
 
This is a C language project that configures the CAN for simple communication.
 
The following scope trace shows CANH (yellow) and CANL (blue) for one transmission. Logic 0 is dominant (CANH=3.5, CANL=1.5V). Logic 1 is recessive (CANH=2.5, CANL=2.5V)

The CAN interface requires a bus driver to create the CANH and CANL signals.


 
Derived from Texas Instrument code
  • can_to_uart_bridge_LP_MSPM0G3507_nortos_ticlang
  • gpio_toggle_output_LP_MSPM0G3507_nortos_ticlang

Hardware Required

  • Two MSPM0G3507 LaunchPad™ Development Kits (LP-MSPM0G3507)
  • Two TCAN1057AVDRQ1 circuits (use driver that can create 3.3V digital output
Pin assignments
  • Output: PA0 is red LED1, index 0 in IOMUX PINCM table
  • CAN_Tx is PA12
  • CAN_Rx is PA13
LaunchPad Jumpers
  • Remove J16 J17 J18: Disconnects light sensor from the microcontroller PA22 PA27 PA26
  • J5: Connects PB22 to blue LED2
  • J6: Connects PB26 to red LED2
  • J7: Connects PB27 to green LED2
