    I want to build a small data logger which can accept either an RS232 or RS485 input. I want to use a uC rather than buy an existing datalogger and build up a circuit myself.

    Before I even look into the data logging side. Can anyone point me in the right direct on how to get a serial input into a uC and process it?

    I have some experience using the TI MSP430 family so would prefer to stick with this but I am open to options.

    You'll have to look for a UART module in the µC of your choice. The UART manages serial I/O. In addition you will require an RS232 or RS485 interface IC, those are available from many vendors.

    The UART function can be realized in software (example), if no hardware UART is available. But the MSP430 family offers a HW UART.
