Function Documentation

◆ LaunchPad_Init()

void LaunchPad_Init ( void  )

Initialize LaunchPad.

Initialize LEDs and switches on MSPM0G3507 LaunchPad

  • PA0 output RED LED1, negative logic
  • PB22 output BLUE LED2, positive logic
  • PB26 output RED LED2, positive logic
  • PB27 output GREEN LED2,positive logic
  • PA18 input S1 switch, positive logic
  • PB21 input S2 switch, negative logic
Parameters
none
Returns
none
Note
In most ECE319K example code, this function is called first and will reset and enable power to Port A and Port B
Warning
Do not call this twice

◆ LaunchPad_InS1()

uint32_t LaunchPad_InS1 ( void  )

Input S1.

Read S1, positive logic switch on PA18

Parameters
none
Returns
0 if S1 is not pressed, 0x00040000 if S1 is pressed
See also
LaunchPad_Init()

◆ LaunchPad_InS2()

uint32_t LaunchPad_InS2 ( void  )

Input S2.

Read S2, negative logic switch on PA18. The software converts to positive logic.

Parameters
none
Returns
0 if S3 is not pressed, 0x00200000 if S2 is pressed
