3.3 Modification on Universal Motor Control Lab Example

Some minor software modifications are needed for the Universal Motor Control Lab software example to support LAUNCHXL-F280039C with BOOSTXL-LMG2100-MD. See the following steps to make the modifications.

  1. Go to “src_board/hal.c”, comment out the definition for GPIO23 (Line 3606–Line 3609).
    BOOSTXL-LMG2100-MD Comment Out the Definition for GPIO23 Figure 3-3 Comment Out the Definition for GPIO23
  2. Open “src_board/user_mtr1.h”, change MACRO definition USER_M1_SIGN_CURRENT_SF to (1.0f) (Line 628).
    BOOSTXL-LMG2100-MD Make Sure USER_M1_SIGN_CURRENT_SF is (1.0f) Figure 3-4 Make Sure USER_M1_SIGN_CURRENT_SF is (1.0f)
  3. Open “src_board/user_mtr1.h”, change define USER_M1_OVER_VOLTAGE_FAULT_V (58.0 f) and define USER_M1_OVER_VOLTAGE_NORM_V (55.0f) (Line 644 and Line 647).
