    MSP430f5528 with CC2500

    hi i have written an example code to transmit data is it correct ?? please check #include<msp430.h> #include<msp430f5528.h> #include "include.h" #include<stdio.h> #include<math.h> ///////////////////////////////////////////////////////////////////////////// extern char paTable[]; extern int paTableLen; int test[10]; char txBuffer[4], received_ch; unsigned int i; /////////////////////////////////////////////////////////////////////////// void main (void) { WDTCTL = WDTPW +WDTHOLD;// STOP WATCHDOG TIMER PMMCTL0 = PMMPW; //OPEN PMM MODULE PM5CTL0 &= ~LOCKLPM5; P4DIR |= BIT7; // Set P4.7 to output direction P4OUT &= ~BIT7; TI_CC_Wait(500); //software delay to give the CC2500 time to startup...
