The numbr of display panels daisy-chained together. Acts as a multiplier of the total number of columns.
The number of columns supported by a single display panel.
Disable the PWM hardware subsystem to create pulses. Typically, you don't want to disable hardware pulsing, this is mostly for debugging and figuring out if there is interference with the sound system. This won't do anything if output enable is not connected to GPIO 18 in non-standard wirings.
The type of GPIO mapping of the device.
In case the internal sequence of mapping is not "RGB", this contains the real mapping. Some panels mix up these colors.
Limit refresh rate of LED panel. This will help on a loaded system to keep a constant refresh rate. <= 0 for no limit.
Panel type. You'll almost always just want to assign this an empty string, but certain panels (FM6126) require an initialization sequence.
The number of parallel chains connected to the Pi. Acts as a multiplier of the total number of rows.
A special string representing selected pixel mappers used to match the current display panel arrangement.
Use LedMatrixUtils.encodeMappers() to conveniently get the formatted string from a list of mappers.
Set PWM bits used for output. The maximum value is 11. Lower values will increase performance at the expense of color precision.
The lower bits can be time-dithered for higher refresh rate.
Change the base time-unit for the on-time in the lowest significant bit in nanoseconds. Higher values will provide better image quality (more accurate color, less ghosting) at the expense of frame rate.
The number of rows supported by a single display panel.
Print the current refresh rate in real-time to the stderr.
The initial brightness of the panel in percent.
