This code example prints the full list of supported MCU vendors, families, groups, and individual MCU part numbers. The condition for this example to work properly is that F_OpenInstancesAndFPAs, and F_Initialization has correctly initialized the given fpa index (1 to 64). If testing adapter 1, the user should call F_Set_FPA_index(1) before this code executes.

The code below is used to initialize the drop-down menus seen in the GUI demos that can be found in the install Elprotronic\ARM\API-DLL directory.

The sequence is as follows:

  • Get Vendor List

    • Call F_Get_MCU_Name_list( MCU_VENDOR_LIST, k ); in a loop to read all supported vendors

      • This generates a list of vendors but doesn’t actually select one, i.e. TI, ST, or NXP

    • Set current vendor using F_Set_MCU_Family_Group( MCU_VENDOR_LIST, Vendor_list_index );

      • This function selects one vendor from the list, with given index, i.e. select ST vendor.

  • Get Family List from selected vendor:

    • Call F_Get_MCU_Name_list( MCU_FAMILY_LIST, k ); in a loop to read all families in selected vendor

      • This generates a list of MCU families for one specific vendor, i.e. STM32-F0, STM32-F1, etc.

    • Set current family using F_Set_MCU_Family_Group( MCU_FAMILY_LIST, Family_list_index );

      • This function selects one family from the list, with given index. At this point the code has selected one vendor and one family from that vendor, i.e. select STM32-F0 family.

  • Get Group List from selected family of selected vendor. Groups sub-divide families into similar MCUs.

    • Call F_Get_MCU_Name_list( MCU_GROUP_LIST, k ); in a loop to read all groups in selected family in selected vendor.

      • This generates a list of groups for selected family within selected vendor, i.e. STM32F0x0, STM32F0x1, STM32F0x2, and STM32F0x8

    • Set current group using F_Set_MCU_Family_Group( MCU_GROUP_LIST, MCU_Group_list_index );

      • This functions selects one group from the list, with given index. At this point the code has selected one vendor, and one family, and one group, i.e. select STM32F0x8.

  • Get MCU part number list from selected group. This is the final MCU name actually used in the “MCU_name” parameter of the configuration file.

    • Call F_Get_MCU_Name_list( MCU_NAME_LIST, k ); in a loop to read all MCUs in selected group, in selected family, in selected vendor.

      • This generates a list of MCU part numbers, i.e. STM32F038C6, STM32F038E6, etc.

    • Select (not shown below) one MCU from the list by using INT_X F_Set_MCU_Name(char *MCU_name );

      • This function selects one MCU, and changes the configuration of the library to program this specific MCU.
