1.2.2.2 User LEDs (LED1
– LED8)
The eight user LEDs (LED1
– LED8) are under FPGA firmware control. Since the
function of these LEDs is defined by the FPGA firmware, they can have any desired
meaning. Some of the user LEDs are used to indicate some common conditions by the
SDRstick
TM
firmware, shown in Table 1. See Figure 6 for user LED locations.
