Hi guys,
Designing a mini robot with the following motor drivers:
http://focus.ti.com/lit/ds/symlink/drv8402.pdf
I am getting noise on my I2C bus whenever the motor drivers are activated. This is causing various errors on devices I am communication with I2C
Are there any tips on how to cancel out this noise? I am using a 10k pullup with 3.3V from the uP (PIC 33F series) for the I2C SDA, SCL lines.
I know this is not really detailed post, but I am looking for design tips more than anything else.
Any tips would be appreciated. Thanks!
