Please visit the [CCS User's Guide](https://software-dl.ti.com/msp430/esd/MSPM0-SDK/latest/docs/english/tools/ccs_ide_guide/doc_guide/doc_guide-srcs/ccs_ide_guide.html#sysconfig-project-migration) for information about migrating to other MSPM0 devices. ### Low-Power Recommendations TI recommends to terminate unused pins by setting the corresponding functions to GPIO and configure the pins to output low or input with internal pullup/pulldown resistor. SysConfig allows developers to easily configure unused pins by selecting **Board**→**Configure Unused Pins**. For more information about jumper configuration to achieve low-power using the MSPM0 LaunchPad, please visit the [LP-MSPM0G3507 User's Guide](https://www.ti.com/lit/slau873). ## Example Usage Connect the CAN_RX and CAN_TX to TCAN1042DEVM pins as described in TCAN Evaluation Module User's Guide and monitor and transmit CAN-FD packages using mcan_single_message_tx example project or using a CAN Bus Analyzer tool of your choice. The example has the following Nominal and Data Rate frequencies configured: - Nominal Bit Rate (250 KBits/s) - Data Bit Rate (2 MBits/s) Compile, load and run the example. To turn on the LED_1, the example must receive the following package: - ID : 0x03 - DATA[0] = 0x01 To turn off the LED_1, the example must receive the following package: - ID : 0x03 - DATA[0] = 0x00 To turn on the LED_2, the example must receive the following package: - ID : 0x04 - DATA[0] = 0x01 To turn off the LED_2, the example must receive the following package: - ID : 0x04 - DATA[0] = 0x00 Note: There is a known limitation where the example might stop receiving packages if the application halt execution after hitting a breakpoint. It is highly recommended to use free run option while testing the example.
