MSP430F5438A: Any MSP430F5438A Example C/C++ Programs for the TI Smart RF Transceiver Evaluation Board?

Hi Swamy,

Regarding your first question, there a several examples using the GPIO pins for this device in the TI Resource Explorer (or TIREX as we like to refer to it).  The link below should take you right to examples for the MSP430F5438A device.

https://dev.ti.com/tirex/explore/node?node=AP7gpEq4Q6jtlePRvD9mrw__IOGqZri__LATEST&search=msp430f5438a

Here is an example from the TIREX.  It monitors bit 4 on port P1 and toggles bit 0 depending on the state of bit4.

#include <msp430.h>

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop watchdog timer
  P1DIR |= 0x01;                            // Set P1.0 to output direction

  while (1)                                 // Test P1.4
  {
    if (0x010 & P1IN)
      P1OUT |= 0x01;                        // if P1.4 set, set P1.0
    else
      P1OUT &= ~0x01;                       // else reset
  }
}

Here is another example that introduces how to use the interrupt feature of the GPIO pin.

#include <msp430.h>

int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop watchdog timer
  P1DIR |= 0x01;                            // Set P1.0 to output direction
  P1REN |= 0x10;                            // Enable P1.4 internal resistance
  P1OUT |= 0x10;                            // Set P1.4 as pull-Up resistance
  P1IE |= 0x10;                             // P1.4 interrupt enabled
  P1IES |= 0x10;                            // P1.4 Hi/Lo edge
  P1IFG &= ~0x10;                           // P1.4 IFG cleared

  __bis_SR_register(LPM4_bits + GIE);       // Enter LPM4 w/interrupt
  __no_operation();                         // For debugger
}

// Port 1 interrupt service routine
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=PORT1_VECTOR
__interrupt void Port_1(void)
#elif defined(__GNUC__)
void __attribute__ ((interrupt(PORT1_VECTOR))) Port_1 (void)
#else
#error Compiler not supported!
#endif
{
  P1OUT ^= 0x01;                            // P1.0 = toggle
  P1IFG &= ~0x010;                          // P1.4 IFG cleared
}

Now, for you second question, yes.  There are dozens of different MSP430 launchpads, but you will need to program them to monitor your IO pins.  In my opinion that is a lot more work than getting the GPIO on your device to work.

There are examples for various communications interfaces, such as SPI, UART, and I2C.

Hello Dennis,

Thank you very much for the excellent information and the link to MSP430F5438A examples.

I am marking this question as resolved.

I have a related questions please:

Following is the URL you have provided for Register Level Examples:

https://dev.ti.com/tirex/explore/node?node=AMG0G4bDkAUNjJAhdKxRYA__IOGqZri__LATEST&search=msp430f5438a

Is there way to select all the C programs and copy them to a folder on my laptop please?

Again, many thanks for providing help very quickly.
