Microcontroller
DATA
AVR
The 64 samples will be examined in the microcontroller to distinguish between a valid signal
from a corresponding transmitter and signals due to noise. This is done by a time frame check
where the samples are continuously compared to a programmable time window (µC_Limits).
If the samples are within the time window and the received data stream is equal to a program-
mable testword (Testword), this will be indicated by LED D4 on the interface board. After
evaluation of the received data stream, the RF receiver is set back to polling mode.
The timing information (64 samples) can also be evaluated using the functions Testword, Histo-
gram and Timing_List in the RF Design Kit software menus.
