Forum Post: RE: Help with a small fragment of SLAA281b SPI sample code

I have changed the following lines of code (hal_SPI.h):

•  #define halSPITXDONE  !(UCA0STAT&UCBUSY)      /* Wait for TX to finish */
•  #define halSPITXDONE  !(UCA1STAT&UCBUSY)      /* Wait for TX to finish */
•  #define halSPITXDONE  !(UCB0STAT&UCBUSY)      /* Wait for TX to finish */

and codestarted to operatewithout using bitbanging technique. Before, the program got stuck in the loop while(!halSPITXDONE);
