F28377D Project Template

Thank you for both Gautam and Chris’s reply. Your information is useful.

However, what I would like to be that I would like to have a GPIO configuration file which is similar to the forma in the XXX-DevInit_F2803x.c, like:

//--------------------------------------------------------------------------------------

//  GPIO-00 - PIN FUNCTION = PWM1A

    GpioCtrlRegs.GPAMUX1.bit.GPIO0 = 1;     // 0=GPIO,  1=EPWM1A,  2=Resv,  3=Resv

//  GpioCtrlRegs.GPADIR.bit.GPIO0 = 1;      // 1=OUTput,  0=INput

//  GpioDataRegs.GPACLEAR.bit.GPIO0 = 1;    // uncomment if --> Set Low initially

//  GpioDataRegs.GPASET.bit.GPIO0 = 1;      // uncomment if --> Set High initially

//--------------------------------------------------------------------------------------

//  GPIO-01 - PIN FUNCTION = PWM1B

    GpioCtrlRegs.GPAMUX1.bit.GPIO1 = 1;     // 0=GPIO,  1=EPWM1B,  2=Resv,  3=COMP1OUT

//  GpioCtrlRegs.GPADIR.bit.GPIO1 = 1;      // 1=OUTput,  0=INput

//  GpioDataRegs.GPACLEAR.bit.GPIO1 = 1;    // uncomment if --> Set Low initially

//  GpioDataRegs.GPASET.bit.GPIO1 = 1;      // uncomment if --> Set High initially

//--------------------------------------------------------------------------------------

I tried PinMux Utility and the output format is like this:

//

// Port A mux register values

//

// Pin D8 (GPIO1) to GPIO1 (mode 0)

// Pin C8 (GPIO0) to GPIO0 (mode 0)

// Pin A7 (GPIO2) to SDAB (mode 6)

// Pin B7 (GPIO3) to SCLB (mode 6)

#define GPAMUX1_VALUE              0x000000a0

#define GPAMUX2_VALUE              0x00000000

#define GPAGMUX1_VALUE           0x00000050

#define GPAGMUX2_VALUE           0x00000000

Which is not convenient for future modification.

Thank you very much

Best regards,

Barry
