Part Number: LDC1614

How to call a multiplexer on the msp430 that comes with evm to implement the functions described in the related problem

For example, multiple channels can be sequentially turned on, and only one coil is energized or only one coil is sampled at a time.

If there are related examples, can you please provide this?

Thanks

    Hi,

    The process you have described is how the LDC1614 normally functions. When channels are not actively being measured they are driven to ground. If you wish to implement the process described in the previous question, you would need to drive an external multiplexer with GPIO pins from the MSP430.

    Is there some documentation describing the relevant settings or procedures?
    I don't know much about how to call the msp430 pin here to implement my multiplexing idea.If you can provide some, I will be very grateful.
    Thank you again for your answer and wish you a happy life.

    Hi,

    Unfortunately we do not have any documentation specific to this application. If you have an idea of how you want to implement the multiplexers, but do not know how to configure the MSP430 to do so, I would suggest posting in the MSP430 forum. Please note that you will need to write custom firmware for the EVM to implement this functionality.

    Regards,
