Switch and LED interface

Switch and LED interfaces
  • PC0-PC3 is used for JTAG connections to the debugger on the LaunchPad.
  • The LaunchPad connects PB6 to PD0, and PB7 to PD1.
  • If you wish to use both PB6 and PD0 you will need to remove the R9 resistor.
  • Similarly, to use both PB7 and PD1 remove the R10 resistor
