Other Parts Discussed in Thread: SIMPLICITI

hi,

i have the ez430-2500 and i see the code for the demo_AP , i want to know what does the next lines and why:

rssi_int = rssi_int+128;

rssi_int = (rssi_int*100)/256;

Another question is, i read the API of SimpliciTI and i try to use the LINKLISTEN_MILLISECONDS_2_WAIT but it give an error, can anybody give an example of use?

Thanks.

Hi Gaston,

The two lines of code you mentioned are used for scaling the RSSI value into a 100 point scale. Thus, the signed values of rssi_int [-128 to 128] scale to [0-100]. RSSI is the system's Received Signal Strength Indication. The converted number is then sent along with the address, temperature, and other data.

Table of Data:

rssi_int --> converted
-128 --> 0
-64 --> 25
0 --> 50
64 --> 75
128 --> 100

Hope this helps,

Adrian F
