Using the F28377xD Docking Station

Brandon Contino

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

I am very new to the world of microcontrollers and have recently acquired an F28377xD Experimenters kit. Right now I am just trying to get the GPIOs of the docking station to light an LED. I can get the LED on the ControlCARD to flash using the example code, but when I try using a pin on the docking station it will not work. Here are the commands I am using:

GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0;
GpioCtrlRegs.GPBDIR.bit.GPIO34 = 1;
GpioDataRegs.GPBCLEAR.bit.GPIO34 = 1;
GpioDataRegs.GPBSET.bit.GPIO34 = 1;

This is probably a really novice question, so I apologize, but any help would be appreciated.

Brandon,

What pin on the Docking Station have you tied your LED to?

It may be helpful to take a look at the 180cCARD pinout document from controlSUITE:
\controlSUITE\development_kits\~controlCARDs\TMDSCNCD28377D_v1_2\R1_1\TMDSCNCD28377D_180cCARD_pinout_R1_1.pdf

Thank you,
Brett

Hi Brandon,

I hope you're following the same structure as in example code. Also GpioCtrlRegs are EALLOW protected, hence you'll have to implement as follows:

EALLOW;
GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0;
GpioCtrlRegs.GPBDIR.bit.GPIO34 = 1;
EDIS;

GpioDataRegs.GPBCLEAR.bit.GPIO34 = 1;
GpioDataRegs.GPBSET.bit.GPIO34 = 1;

Regards,

Gautam

Turns out I was not connecting to the write pin on the board. I was connecting to the pin of the GPIO, not the pin used for the GPIO. Rookie move. Thanks for your guys' help!
