Part Number: DRV8860EVM I was able to find the microcontroller firmware source via the answer to this question and while I could probably back-out the API it would be really helpful if you could provide documentation of the USB/serial API (e.g., 0xa6…
Hi Brad,
The source code can be found in the DRV8860EVM_MSP430_FIRMWARE.zip file in the Hardware files of the DRV8860EVM.
The direct link is: http: //www.ti.com/lit/zip/slvc596
Depending on the age of the EVM, the source code is either in the…
Hi Nagaraj,
If you are requesting the source code for the loaded on the EVM, it can be found here: www.ti.com/.../slvc596
The Hardware files in the folder www.ti.com/.../DRV8860EVM contains the firmware and board information.
Hello,
You may need to incorporate a small delay between latching high, sending data, and latching low.
Please see the DRV8860EVM firmware as an example to drive the motor. Delay functions are used throughout the program to ensure proper timing…

Hi Mike,
Can you provide more details?
Do you have scope captures of the voltage fluctuation and the current?
What are the settings in the DRV8860?
Is this seen on the DRV8860EVM or a custom PCB? If custom, can you share the schematic?
