Hi All,
I have a custom made board for CC430F5137 and i am trying to work with with the sample code provided by TI for this micro. I am facing problem with Fixed_LT_FIFO_MHZ_915 project. I loaded this this code on my board which is powered from two batteries and code does not work. When I halt the debug session, curssor state is at
while ((RF1AIN&0x04)== 0x04); // chip-ready .
which means chip is not ready. Can anybody help me for this problem..
unsigned char Strobe(unsigned char strobe)
{
unsigned char statusByte = 0;
unsigned int gdo_state;
// Check for valid strobe command
if((strobe == 0xBD) || ((strobe >= RF_SRES) && (strobe <= RF_SNOP)))
{
// Clear the Status read flag
RF1AIFCTL1 &= ~(RFSTATIFG);
// Wait for radio to be ready for next instruction
while( !(RF1AIFCTL1 & RFINSTRIFG));
// Write the strobe instruction
if ((strobe > RF_SRES) && (strobe < RF_SNOP))
{
gdo_state = ReadSingleReg(IOCFG2); // buffer IOCFG2 state
WriteSingleReg(IOCFG2, 0x29); // chip-ready to GDO2
RF1AINSTRB = strobe;
if ( (RF1AIN&0x04)== 0x04 ) // chip at sleep mode
{
if ( (strobe == RF_SXOFF) || (strobe == RF_SPWD) || (strobe == RF_SWOR) ) { }
else
{
while ((RF1AIN&0x04)== 0x04); // chip-ready ?
// Delay for ~810usec at 1.05MHz CPU clock, see erratum RF1A7
__delay_cycles(850);
}
}
WriteSingleReg(IOCFG2, gdo_state); // restore IOCFG2 setting
while( !(RF1AIFCTL1 & RFSTATIFG) );
}
else // chip active mode (SRES)
{
RF1AINSTRB = strobe;
}
statusByte = RF1ASTATB;
}
return statusByte;
}
