MSP430FG4618 ADC12 Memory Register Query

[rshrivas]

Hi,



I am new to MSP430 controller and I presently using SimpliciTI protocol for transmitting ADC samples wirelessly from the End Device to the Access Point. Now the ADC12 has a memory register which is 16 bit (4 MSB bits 0) and this data is read into a 16 bit integer array as shown below.

uint16_t ch1[100];

uint16_t ch2[100];

for ( int t=0; t<100 ; t++)
{
ADC12CTL0 |= ENC; // Enable conversions
ADC12CTL0 |= ADC12SC; // Start conversions
while((!(ADC12IFG &0x02)==1));
ch1[t] = ADC12MEM0;
ch2[t] = ADC12MEM1;
}



But in order to transmit the data using the "smplStatus_t SMPL_Send(linkID_t lid, uint8 *msg, uint8 len)" command I can only transfer 8 bit array (string) and not 16 bit array. But the ADC memory register is 16 bit so need to put the 1st 8 bits of the MSB in one array and the 8 bits of the LSB in another array so that I can easily transmit the two 8 bit arrays easily.

Is there any addressing mode that I can use to store the 8 MSB bits in one array and the 8 LSB bits in another array. Or is there some other way to deal with this issue.


But being new to MSP430 programming I have no idea how can I do that.

Please let me know your suggestions.

Regards

Ravi
