[参考译文] MSPM33C321A：Modbus 支持

• 器件：MSPM33C321A
• 板：LP_MSPM33C321A
• SDK：mspm33_sdk_1_03_00_01
• IDE：Code Composer Studio Theia / CCS 20.5.1
• 编译器：TI ARM Clang 4.0.4.LTS
• 编译配置：NoRTOS、ticlang

• 导入“empty_LP_MSPM33C321A_nortos_ticlang“和“Modbus_controller_LP_MSPM0G3507_nortos_ticlang“
• 将以下.c/h 文件复制 到 “empty_LP_MSPM33C321A_nortos_ticlang“。
  modbus_controller.c/h
  ModbusRTU.c/h
  ModbusRTU_priv.h
  
• 随附的 sysconfig 文件基于“modbus_controller_LP_MSPM0G3507_nortos_ticlang“。
• Cretate 新文件“modbus_msp33_compat.h“、为了避免修改 TI 的 ModbusRTU.c /、 ModbusRTU.h我添加了一个兼容性标头：
  typedef UNICOMM_UART Inst_Regs UART_Regs；
• 添加编译器选项： “-include /empty_LP_MSPM33C321A_nortos_ticlang/modbus_msp33_compat.h“
• 然后在“modbus_controller.h" 如下所示“中添加 include：
  #include “modbus_msp33_compat.h“

如果这根本不是链接器问题、请告诉我。

此致、
正常
