MSPM0G3507 软件IIC一主多从

## Example Summary Empty project using DriverLib. This example shows a basic empty project using DriverLib with just main file and SysConfig initialization. ## Peripherals & Pin Assignments | Peripheral | Pin | Function | | --- | --- | --- | | SYSCTL | | | | DEBUGSS | PA20 | Debug Clock | | DEBUGSS | PA19 | Debug Data In Out | ## BoosterPacks, Board Resources & Jumper Settings Visit [LP_MSPM0G3507](https://www.ti.com/tool/LP-MSPM0G3507) for LaunchPad information, including user guide and hardware files. | Pin | Peripheral | Function | LaunchPad Pin | LaunchPad Settings | | --- | --- | --- | --- | --- | | PA20 | DEBUGSS | SWCLK | N/A |

• PA20 is used by SWD during debugging
  
  • `J101 15:16 ON` Connect to XDS-110 SWCLK while debugging
    
  • `J101 15:16 OFF` Disconnect from XDS-110 SWCLK if using pin in application

| | PA19 | DEBUGSS | SWDIO | N/A |

• PA19 is used by SWD during debugging
  
  • `J101 13:14 ON` Connect to XDS-110 SWDIO while debugging
    
  • `J101 13:14 OFF` Disconnect from XDS-110 SWDIO if using pin in application

| ### Device Migration Recommendations This project was developed for a superset device included in the LP_MSPM0G3507 LaunchPad. 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 Compile, load and run the example.
