    Hi,
    i want to interface MSP432 with bridge sensors.My sensor output is linear with output voltage.
    However the output produce from sensor are in mill volt.
    Can we interface directly to mSP432 or do we need An signal conditioning circuit.?
    can u people provide Microcontroller programaming In CCS studio?

    As long as it doesn't exceed the supply voltage of the uC you can connect it to an analog input and you should get some reading. Your mV signal may only cover a small portion of the range of the analog input, so if you need to maximize the resolution of your reading you will need to condition/shift the signal with an opamp (ie. add a gain to the signal).
