In the energia tutorial it says that "LaunchPad pins can source (provide positive current) or sink (provide negative current) up to 40 mA (milliamps) of current to other devices/circuits. " http://energia.nu/Tutorial_DigitalPins.html Is that correct for the Stellaris Launchpad? In the documentation for the LM4F120 it gives drive strength options of 2, 4, or 8 mA, and says up to 4 pins can sink 18 mA. Where does the 40mA come from? Can the MSP430 source/sink that much? I note that the Arduino documentation says the same 40mA, so wondered if this specification was accidentall
