Ken,
We do not sell devices pre mounted on boards for evaluation unless you purchase an EVM,
There is an EVM on the web at the link here that you could buy an EVM

Hello Darshan,
Please see the following TID using on of TI's motor driver chips + MSP430 for some guidance on your application. www.ti.com/.../DRV8881EEVM
Beyond the above link, we do not have nay collateral related to your specific application…
Hi Gerald,
There is no source code for the operation that you requested.
You could use code from a similar EVM (like the DRV8812EVM or DRV8881EEVM ) and modify the code to issue serial interface commands when an interrupt occurs.
Hi Bhavin,
Please see the Application Report: www.ti.com/.../slva443 for an example of the code.
There is similar code used in the DRV8881EEVM. This code is available in the DRV8881EEVM software file.
Hi Ming,
The DRV8881EEVM can provide a starting point. The DRV8881E allow high levels of microstepping by providing two reference voltages and controlling the Phase and Enable signals.
The firmware provided with the device is an example of how to control…
Part Number: DRV8842 Other Parts Discussed in Thread: DRV8824 , DRV8881EEVM
I am using DRV8842 to control movement in a stepper motor. The step angle in my stepper motor is 1.8 degrees. How do I use microstepping to rotate the stepper motor by 1 step…
Other Parts Discussed in Thread: TMDXIDDK379D , DRV8711 , DRV8880 , DRV8412 , DRV8881EEVM Hi,
Can I use TMDXIDDK379D for bipolar stepper motor control. I need to use PID position control. Micro stepping and trajectory planning are needed.
thanks

Other Parts Discussed in Thread: DRV8711EVM , DRV8881EEVM Does anyone have any idea what would cause the winding current to be distorted in this way. I have tried a few different settings but the distortion stays about the same. I am moving very slowly…
