The DSP-board

A.3.1 – The LEDs

The LEDs are connected to the P7-connection on the DSP-board. Here’s a code segment

displaying how to use them:

(please note that setting the corresponding flag to 0 illuminates the LED)

void Init_Diode(void){

EALLOW;

GpioMuxRegs.GPBMUX.bit.C4TRIP_GPIOB13=0; //Right

GpioMuxRegs.GPBMUX.bit.C5TRIP_GPIOB14=0; //Center

GpioMuxRegs.GPBMUX.bit.C6TRIP_GPIOB15=0; //Left

GpioMuxRegs.GPBDIR.bit.GPIOB13=1; //Write

GpioMuxRegs.GPBDIR.bit.GPIOB14=1;

GpioMuxRegs.GPBDIR.bit.GPIOB15=1;

GpioDataRegs.GPBDAT.bit.GPIOB13=1; //0=ON, 1=OFF

GpioDataRegs.GPBDAT.bit.GPIOB14=1;

GpioDataRegs.GPBDAT.bit.GPIOB15=1;

EDIS;

}

void DiodOn(int diodNbr){

if (diodNbr==1) GpioDataRegs.GPBDAT.bit.GPIOB15=0;

if (diodNbr==2) GpioDataRegs.GPBDAT.bit.GPIOB14=0;

if (diodNbr==3) GpioDataRegs.GPBDAT.bit.GPIOB13=0;

}

void DiodOff(int diodNbr){

if (diodNbr==1) GpioDataRegs.GPBDAT.bit.GPIOB15=1;

if (diodNbr==2) GpioDataRegs.GPBDAT.bit.GPIOB14=1;

if (diodNbr==3) GpioDataRegs.GPBDAT.bit.GPIOB13=1;

}
