EZ430-RF2560

Other Parts Discussed in Thread: CC2560

I want to see if I can send a HCI command to my 2560 using the EZ430 usb kit.  My understanding is I need to setup UART 2, power the cc2560, Send a HCI reset, on any return data I want to turn on an LED just as a test to see something is working.  My LED isn't turning on... I think I am not powering the cc2560 correctly but I don't know how to verify that.

Setup the LEDs

P1DIR |= 0x01;
    
P1DIR |= 0x02;

Setup UART 2 to 115200 8n1.  I have done this and I can see data on J2.

P9SEL = 0x30;                             // P9.4,5 = USCI_A2 TXD/RXD

P1SEL = 0x18;                             // P1.3,4 = USCI_A2 RTC/CTS





UCA2CTL1 |= UCSWRST;                      // **Put state machine in reset**

UCA2CTL1 |= UCSSEL_2;                     // Clock Source: SMCLK



UCA2BR0 = 0x09;                           // 1MHz 115200 (see User's Guide)

UCA2BR1 = 0x00;                           //

UCA2MCTL = UCBRS_1+UCBRF_0;               // Modulation UCBRSx=1, UCBRFx=0



UCA2CTL1 &= ~UCSWRST;                     // **Initialize USCI state machine**

UCA2IE |= UCRXIE;                         // Enable USCI_A2 RX interrupt

// Echo back RXed character, confirm TX buffer is ready first

#pragma vector=USCI_A2_VECTOR

__interrupt void USCI_A2_ISR(void)

{

  switch(__even_in_range(UCA2IV,4))

  {

  case 0:break;                             // Vector 0 - no interrupt

  case 2:                                   // Vector 2 - RXIFG

    P1OUT |= 0x02;  //Turn on led


    break;

  case 4:break;                             // Vector 4 - TXIFG

  default: break;

  }

}

Power on the cc2560.  I don't know how I can verify I am doing this correctly.  I am doing the following

//setup the clock on p2.6

P2SEL |= 0x40;



//set up port p2.7 for power

P2DIR |= 0x80;   //set up as output

Send my HCI reset command

while (!(UCA2IFG&UCTXIFG));

UCA2TXBUF = 0x01;



while (!(UCA2IFG&UCTXIFG));

UCA2TXBUF = 0x0c;



while (!(UCA2IFG&UCTXIFG));

UCA2TXBUF = 0x03;



while (!(UCA2IFG&UCTXIFG));

UCA2TXBUF = 0x00;
