    Folks,

    I've searched the datasheet for MSP430G2210, but I can't seem to find how much can its I/O pin source and sink. The only number I was able to find was 48mA max combined for a port.

    What I want to do is to drive an LED with 20mA. Either way would do: source or sink.

    Does anyone know the numbers?

    It's right in the datasheet on page 17, -0.6v drop @ 6mA for source and 0.6v @ 6mA for sink. You need a LED driver for 20mA.

    Chips like that keep 2n2222 in business.
