.br
The green activity LED (GPIO 47) may be written.
.br
The red power LED (GPIO 35) may be written.
.br
The high USB power mode (GPIO 38) may be written.
.br
.SS Pi3B
.br
.br
The green activity LED and the red power LED are not writable.
.br
The USB power mode is fixed at 1.2 amps (high power).
.br
.br
.br
The power LED (red) may be written on type 3 boards (GPIO 35).
.SS DMA Channels
.br
.br
The secondary channel is only used for the transmission of waves.
.br
.br
If possible use one of channels 0 to 6 for the secondary channel (a full channel).
.br
.br
A full channel only requires one DMA control block regardless of the length of a pulse delay. Channels 7 to 14 (lite channels) require one DMA control block for each 16383 microseconds of delay. I.e. a 10 second pulse delay requires one control block on a full channel and 611 control blocks on a lite channel.
.br
.br
The high USB power mode GPIO may be written (GPIO 38 for type 3 boards).
