This tool uses BeagleLogic to decode the output of LEDscape using the Octoscroller hardware on Adafruit 16x32 and 32x32 LED panels for the purpose of debugging the LEDscape code and verifying the LED panel scan pattern, since I haven't found it clearly documented anywhere.

From http://trmm.net/Octoscroller: The panels are built as six parallel shift registers, each with 32 bits, and twelve 16-channel constant current LED drivers. The connectors have six data and six control inputs each: R1, G1, B1, R2, G2 and B2, and A, B, C, CLK, LTC, OE. The three address select lines, A, B, C, select which two rows are currently displayed (0/8, 1/9, 2/10, etc). On each falling edge of the CLK line, a new bit is shifted in on the six data inputs. On the falling edge of the LAT line, the new data is latched and, when OE is held low, displayed. To save on GPIO lines, the P
