- Install and start Modus Toolbox and select a workspace to be used (tested with Version 3.1 and 3.2).
- Import the project with the import wizard by pressing 'File' – 'Import…'.
- Select 'General' – 'Existing Project into Workspace' and press 'Next'.
- Select the archive file by pressing 'Browse…'.
- Deselect the subprojects - only the main project must be ticked. Press 'Finish'.
- Right click the 'proj_cm0p' folder and press 'Import as Project'.
- Right click the 'proj_cm4' folder and press 'Import as Project'6.
- Click on the main project item, wait a second until the quick view panel loads and start the 'Library Manager' on it.
- Press the 'Update' button
- If the update failed, try it again. If this also fails try to clean the project, before trying it again.
- It should now be possible to build the project without errors.
- To flash the project onto the hardware, connect the MiniProg4 Programming adapter using the 10-pin flat cable. Before the flashing can be started the 'Start' button on the BMS (right-most button as seen from the front) must be pressed AND HELD until the programming is finished! Use the green play button on the bottom left - 'Quick Panel' - 'Launches' - 'IMR_SW_PSoC6_BatteryManagement Program Application (KitPro3_MiniProg4)' to initiate the process.
- OPTIONAL: If the debug UART is needed (status and debug messages from system) also connect the TX pin on the controller board to pin 8 of the MiniProg4 (see figure above). In ModusToolbox open a Terminal and select the COM port the Debugger is on:
Precise definition of the software and its features can be found in the close-to-code documentation on top of each file, at the specific function itself and in the software documentation.
