DRV8462EVM: Assistance with DRV8462EVM and Code Composer Studio Integration

Part Number: DRV8462EVM
Other Parts Discussed in Thread: DRV8462, MSP430F5338, LAUNCHXL-F280025C

Tool/software:

Dear Customer Support Team,

I hope this message finds you well.

We have been successfully using the GUI application to configure the DRV8462EVM and achieve the desired threshold limits with a specific configuration to our steeper's motor. Now, we would like to move to the next step and work with Code Composer Studio.

Could you please provide guidance or documentation on the following:

  1. How to connect the DRV8462 to start working with the driver using Code Composer Studio?
  2. Are there specific guides or resources available for integrating the driver with your IDE?
  3. Do I need an additional development kit to connect the driver, or is the DRV8462EVM equipped for this purpose?

Thank you in advance for your support. Looking forward to your response!

Best regards,
Shahar Cohen

    Hello Shahar,

    Thank you for posting in this forum.

    The DRV8462EVM uses an on-board MSP430F5338 MCU to control the DRV8462. In addition to this the EVM has on-board ez430 debugger hardware for two proposes, 1. USB to UART VCP for GUI communication and 2. Interfacing directly with TI CCS for code development and reprogramming the MSP430F5338. With you customer code the EVM would not longer work with the GUI unless the EVM is reprogrammed with the firmware to support to the GUI which can be done using the GUI File > Program Device menu.

    Like mentioned above the EVM has the necessary hardware to directly work with TI CCS for MSP430.

    The EVM CCS project and source code files can be downloaded from the EVM webpage https://www.ti.com/tool/DRV8462EVM, using this link https://dr-download.ti.com/software-development/support-software/MD-abhVTZhobH/1.0.2/DRV84XX-DRV89X2-DRV82X2-EVM-SOFTWARE.zip. The zip file contains a separate folder for the EVM firmware files.

    Thanks for the response, 

    what is the correct setup for the DRV8462EVM to work with F280025C?

    Hello Shahar,

    The onboard provision for LAUNCHXL-F280025C was for TI internal purpose only and is not documented for external use. However, you are free to use with it if you are familiar with the F280025C or any other controller you may want to use. All the DRV pins can be isolated from the header and used for connecting to the external controller. The connections to the LAUNCHXL-F280025C connector are shown in the schematic diagram which can be downloaded from the hardware files in the EVM webpage. 

    Keep in mind the DRV8462 requires a VCC input. The VCC on the EVM is derived from the USB voltage - please refer to the schematic. So, even if you are not using the onboard MCU and the GUI the USB must be connected to a computer so that the DRV8462 gets the VCC 3.3 V supply voltage. Without the VCC supply the DRV8462 device will not communicate with an external controller. 

    Thank you.
