DRV8462EVM: DRV8462EVM

Hi,

Can I please receive help to program the DRV8462 EVM using the scripting function to go forwards until stall and then reverse until stall for a calibration step and then use the step counts as a means to change direction and not stall detection? the reason is because the stall detection as a method to change direction for calibration is fine (to determine the number of counts until end position) but as a long lasting method our solar cleaning robot will be damaged as the stall impact is a lot over time.

Kind regards,

Hi Phillip,

Could you please clarify were you requesting standalone operation of the EVM like you described? If this is the case you will have to modify the firmware of the EVM to make it run standalone. This can be done by modifying the C-program running in the microcontroller of the EVM. This was developed using TI CCS https://www.ti.com/tool/CCSTUDIO. The complete C-source code and CCS project for the EVM firmware is available for download from the EVM webpage, https://www.ti.com/tool/DRV8462EVM. Here's the download link, https://dr-download.ti.com/software-development/support-software/MD-abhVTZhobH/1.0.2/DRV84XX-DRV89X2-DRV82X2-EVM-SOFTWARE.zip.

The scripting function will be available only while the EVM is connected to a PC and the PC is running GUI which will be running the JavaScript.

We have provided examples for the JavaScript built-in with the GUI. For whatever functions you required you'll have to develop your application specific JavaScript. This is standard JavaScript based. If you run into issues with your custom script we'll be happy to support you to resolve the issue.

Regards, Murugavel
