In at least two places the Energia documentation claims that LaunchPad pins can source or sink up to 40 mA. Is that true of all (or any) of the launchpads supported by Energia? (i.e., Stellaris/Tiva, Tiva Connected, MSP430, Fraunchpad, C2000, CC3200) For the Stellaris launchpad, the documentation for the LM4F120 gives drive strength options of 2, 4, or 8 mA, and says up to 4 pins can sink 18 mA. So where does the 40mA come from (or go to)? Yet energia.nu says: "LaunchPad pins can source (provide positive current) or sink (provide negative current) up to 40 mA (milliamps) of current to
