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 requirements…
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 in…
Part Number: DRV8860EVM Other Parts Discussed in Thread: DRV8860 I would like to control the DRV8860 EVM using labview. I see that the EVM comes with an executable that looks like it is built on labview. Could you provide the source code for this executable…
Part Number: DRV8860EVM Other Parts Discussed in Thread: DRV8860 , Where can I download the source code for this application? I'd like to copy/paste sections of it into our product application (an embedded system) so I don't have to re-invent the wheel…
Hi Manu,
You downloaded the EVM firmware from ti.com? When I download the software files for the DRV8860EVM, I only see the GUI files.

Part Number: LM2733 Other Parts Discussed in Thread: DRV8860EVM , DRV8860 , I'm having stability troubles with my design for the LM2733XMF. I have been using the Power Stage Designer Tool to create bode plots for my design and analyze the stability. My issue…
Hi Robert,
Please see the attached scope capture from the DRV8860EVM. An open load fault was created on OUT3 to allow show the full 16 bits of data.
In addition to the image, the DRV8860EVM firmware can be found in the Design files (Hardware: DRV8860EVM…
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?
Hi Eagle,
Please considered getting a DRV8860EVM to compare the transactions against yours.
Also, please disconnect the loads if possible.
Then perform a data register write and data register read using Figures 12 and 25 of the datasheet. Is this working…
