5 This is an example capture of a 32x32 pixel 1/16 scan "normally addressed"
6 HUB75 LED matrix. The matrix is being driven by a Raspberry Pi 3b+ with
7 https://github.com/hzeller/rpi-rgb-led-matrix at 12 PWM bits per color.
9 The A, B, C and D lines are address lines that select two rows at a time that
10 can have LEDs on. Address 0 selects rows 0 and 16, address 2 selects row
13 R1, G1 and B1 lines are binary data on the different color LEDs on the first
14 line and R2, G2 and B2 for the second line. The data is clocked into constant
15 current driver chips that act like 74595 shift registers.
17 It is possible to build bigger displays by chaining the data to more panels.
23 The logic analyzer used was a DreamSourceLab DSLogic Plus (at 100MHz):
