RTOS/MSP432P401R: Set a entire GPIO port at once (TI-RTOS driver)

Part Number:MSP432P401R

Tool/software:TI-RTOS

Hello,

I'm trying to connect a RA8835 LCD controller to the MSP432. I'm using the SimpleLink MSP432 SDK based on TI-RTOS. For the needed 8-bit bi-directional data bus i want to use the entire port 7. The GPIO driver (GPIO_write()) allows me only to set one pin at a time.

I also tried to use the Generic PIN & GPIO driver (PIN.h). As soon as I try to call a function of the Generic PIN & GPIO driver an error occurs:

 undefined first referenced
  symbol       in file     
 --------- ----------------
 PIN_open  ./display.obj   

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "VRC_main_MCU.out" not built

>> Compilation failure
makefile:167: recipe for target 'VRC_main_MCU.out' failed
gmake[1]: *** [VRC_main_MCU.out] Error 1
makefile:160: recipe for target 'all' failed
gmake: *** [all] Error 2

**** Build Finished ****

What am I doing wrong? Or is there a other way to set the entire port at once?

Thank you for your help & kind regards

Kevin
