Hi everyone,
I'm trying to interface an external ADC with the MSP430F1611's SPI.
I've written the code to initialize the SPI (seen below), but I now want to test my Init_SPI by writing some data to it and probing it using the scope to see that I've written data to it.
Eventually, I want to get data from an external ADC using SPI and store it in memory.
Can anyone point me in the right direction?
Thank you so much! Much appreciated.

void Init_SPI(void) { P3SEL |= 0x3F; // Select P3.0,1,2,3,4,5 P3DIR |= 0x0B; // Select P3.1,3 as output directions P3OUT &= ~0x01; ME1 |= USPIE0; // ENABLE USART0 SPI UCTL0 |= CHAR + SYNC + MM; // 8-bit data, SPI mode UTCTL0 |= CKPH + CKPL + SSEL1; // Inv.delay, ACLK UBR00 = 0x2A; // Baud Rate = 115200 UBR10 = 0x0; UMCTL0 = 0x0; // Clear Modulation UCTL0 &= ~SWRST; // Initialize USART state machine
//_BIS_SR(LPM3_bits + GIE); // Enter LPM0 w/interrupt
} //end Init_SPI
