CCS/MSP430F5528: DriverLIB/MSPWARE help

Tool/software: Code Composer Studio

Hi,

I'm using the GPIO API included with driver Lib to turn ports 5.2/5.3/j.0/j.1 on, and I can't get them to turn on. I've connected LED's to them to ensure if they're turning on or not and can see that they're not. Here's the code:

#include "driverlib.h"

#include <msp430.h>

void main (void)

{

//Stop WDT

WDT_A_hold(WDT_A_BASE);

//PA.x output

GPIO_setAsOutputPin(GPIO_PORT_P5, GPIO_PIN2+GPIO_PIN3);

GPIO_setAsOutputPin(GPIO_PORT_PJ, GPIO_PIN0+GPIO_PIN1);

//Set all PA pins HI

GPIO_setOutputHighOnPin(GPIO_PORT_P5, GPIO_PIN2+GPIO_PIN3);

GPIO_setOutputHighOnPin(GPIO_PORT_PJ, GPIO_PIN0+GPIO_PIN1);

P1DIR |= 0x01; // configure P1.0 as output

volatile unsigned int i; // volatile to prevent optimization

while(1)

{

P1OUT ^= 0x01; // toggle P1.0

for(i=10000; i>0; i--); // delay

}

//Enter LPM4 w/interrupts enabled

__bis_SR_register(LPM4_bits + GIE);

//For debugger

__no_operation();

}

Ports 5.2 and 5.3 are XT2OUT and XT2IN. Just some additional information to help.

Hi Raghav,

Substitute: P5DIR |= (BIT2 | BIT3) for GPIO_setAsOutputPin(GPIO_PORT_P5, GPIO_PIN2+GPIO_PIN3); // set P5.2, P5.3 as outputs

and

Substitute P5OUT |= (BIT2 | BIT3) for GPIO_setAsOutputPin(GPIO_PORT_PJ, GPIO_PIN0+GPIO_PIN1); // turn on LEDS

Substitute P5OUT &= (~BIT2 | BIT3) for GPIO_setAsOutputPin(GPIO_PORT_PJ, GPIO_PIN0+GPIO_PIN1); // turn off LEDS

Let me know if this does not work for you.

Hi,

I fixed the driverLib issue and using GPIO_setAsOutputPin(GPIO_PORT_P5, GPIO_PIN2+GPIO_PIN3); worked for me. The dev board by Ti was missing a couple of resistors needed to make the ports worked.

However, I still cannot get port's J.0 and J.1 to work, help for that would be appreciated!

Hi Raghav,

PORT J should work the same way. What specifically is not working with these 2 pins? Are you attempting to use these pins while a debugger is attached? If not, what is connected to them?

Hi,

I’m trying to toggle these pins to a high state while the debugger is connected. When I run it, the LED’s connected to all other GPIO ports work, while the port j does not.

Hmmm, the problem is the CPU can't control PORTJ while connected to the debugger. If you remove the debugger do the port pins toggle?

Hi Dennis, yes the ports work when the debugger is disconnected, but they do not work in any uniform matter. Either of the J ports start working sporadically when disconnected and don't usually follow the API Command

Ok.

Out of curiosity, are you using the MSP-EXP430F5529 Launchpad?

I see on the schematic that pins J.0 and J.1 are connected to anything on the board. How are you connecting to the port J pins?

Can you send me a portion of your schematic or drawing showing exactly what is connected to ALL of the PORTJ pins?

Hi,

I am using the MSP-TS430RGC64USB. I've added a schematic for it. The J ports seem to be connected to the pin.

Ok, and you have nothing connected to either J9 or J10 (those signals go there too)?

Can you provide me with a copy of your latest code?
