Convert lcd segment in msp430f427 into GPIO

I need to convert lcd segments in msp430f427 (PIN NO. 12 TO PIN NO. 43 ) TO GPIO.

Please help if it is possible or not. Please confirm how many of them can be converted to GPIO, and how.

I have downloaded the datasheet but it is not showing even they are multiplexed or not. Not even what port pin they will be if used as GPIO.

Please help.

  • Unfortunately pin 12 to pin 43 are only for LCD control.

    Are you really sure about it.
    If it is so, is it possible to drive 16x2 dot matrix lcd with it.
    Please help.

    If you mean one of those standard HD44780 compatible LCDs...

    ...then no, the pins for driving the LCD segments are not usable to connect to such a display. These LCDs are connected to GPIO pins. Your MSP can control this display, but it only has a few GPIO pins, so maybe not many left then.

    Using one of the HD44780 type displays with this MSP430 does not make sense. You should chose another processor.
