+# Purpose:
+# . Write lists of complex weights to SC1 beamformer registers
+# Description:
+# . This example writes complex(1,0) to every weight address.
+# . The SC1 gateware design uses 2 beamformer units:
+#   . Beamformer unit for X pol
+#     . 12 (dishes) inputs
+#       . 24 (subbands) weights per input
+#   . Beamformer unit for Y pol
+#     . 12 (dishes) inputs
+#       . 24 (subbands) weights per input
+# . The weights to upload are contained in an array of the following dimensions:
+#   . [16 bands][2 pols x,y][12 inputs 0..11][24 subbands 0..23]
+#     . Inputs 0..11 map to telescopes RT2..RTD
+#     . The 24 subbands make up Compound Beam 0 = the central PAF compound beam.
+#     . The 24 subbands per UniBoard belong to a global subband range of 384 
+#       subbands (300MHz) divided across 16 UniBoards (only 1 FPGA, FN0, per 
+#       UniBoard is used to provide CB0).
+#       . Subband 0  of central UniBoard  0 = subband   0 of 0..383
+#       . Subband 23 of central UniBoard 15 = subband 383 of 0..383
+# . The weights are 16b complex (32b per weight).
+# . The beamformer input data is 8b complex (16b total).
