Hi,
Working on a project involving the STSPIN840 motor driver connected to a PIC32MK microcontroller,trying to implement current sensing for accurate motor control. The STSPIN840 has the current sensing pins SNSA, SENSEA1, and SENSEA2 for each channel.
I would appreciate any advice on the following points:
Current Sensing Setup: What is the recommended configuration for using these pins to measure the motor current accurately?
RSNS = 330 mohm
Connection to ADC: connected the sense pins to the ADC of the PIC32MK. When reading ADC getting current values very high(in 10s of A ) compared to the the motor rated values(<1A)
Are there any particular considerations or issues I should be aware of when interfacing these pins with the microcontroller’s ADC?
Any insights, diagrams, or documentation references would be greatly appreciated!
Thank you in advance!
