14.2(e) - Serial Communication on the MSP430: SPI - Receiving a Byte as a SPI Master

Just one phrase "writing a dummy byte" solved my problem :-) Thanks!

Excellent series, thanks Brock! If SW1 and SW2 are on the same port though (as they are on the 6989 launchpad) then you need to check which BIT of the P1IFG is set once inside the PORT1_VECTOR. Simply use this code segment to check the logic: if(P1IFG & BIT1){ etc... // checks BIT1 of P1IFG which is the bit for pin 1.1 or SW1

Honeywell force sensors for instance don't have RX line at all so they start transmitting output data in a slave mode as soon as CLK is applied.

this is good idea when you dont have slave , you can you same mcu rxbuffer anad trbuffer
