hello,

I am working on MSP430FW425 microcontroller . I want to use three inductors to sense the rotation. please reply me whether is it possible to make three inductors work on this ic

Hi,

you have 4 Scan IF input channels so you can connect three inductors to the MSP430FW425.

The Rotation Detection With The MSP430 Scan Interface Application Report shows the implementation with two sensor. This could be a good starting point for you.

Best regards,

Britta

hi,
thanks for the suggestion. the application report you have mentioned has one inductor and two inductor sample codes and solutions. I am interested to know whether there is solution for three inductor so that it would be easy for me

Hi,
as far as I know we only provide the example for two inductors.
But maybe this can already help to indicate to you how to adapt from one inductor to two so that you know what is important to take care of.

Best regards,
