Board level cameras: inputs and outputs
The following Guppy board level cameras are available:
Guppy board level cameras have physically 4 I/Os and logically 4 inputs and
4 outputs : Outputs can be disabled in the Output Control Register via 0x00
(register 0xF1000320 bit 11..15). Inputs are always enabled.
Board level cameras: pulse-width modulation
The 4 inputs and 4 outputs are independent. Each output has pulse-width
modulation (PWM) capabilities, which can be used (with additional external
electronics) for motorized speed control or autofocus control.
Period (in µs) and pulse width (in µs) are adjustable via the following regis-
ters (see also examples in Chapter
PWM: Examples in practice on page 105):
