Add more LEDs with Fading

Hello Community,

I found this really amazing Code from oPossoum in the Code Vault for fading a LED. The problem is, I would like to make both LED on the launchPad fading.

I am really new to MSP430G2553 and played a lot with the Code, tried to understand Clocks, Interrupts, etc. , but I am not able to get it :/

Can anybody help me how to or give me a good advice? Thanks!

#include <msp430.h>
#include <stdint.h>

void main(void)
{
    WDTCTL = WDTPW | WDTHOLD;
    DCOCTL = 0; BCSCTL1 = CALBC1_16MHZ; DCOCTL  = CALDCO_16MHZ;
    P1DIR = P1SEL = BIT6;
    TACCTL1 = OUTMOD_7; TACTL = TASSEL_2 | MC_2 | TAIE;
    _EINT();
}
#pragma vector = TIMER0_A1_VECTOR
__interrupt void timer_a1_isr(void)
{
    static uint32_t x = 0x00100000L;
    static unsigned d = 1;
    TACCR1 = x >> 16;
    volatile unsigned z = TAIV;
    if(d) {
        x += (x >> 7); if(x > 0xF8000000L) d = 0;
    } else {
        x -= (x >> 7); if(x < 0x00200000L) d = 1;
    }
}
