IO_OUTP_CTRL 1-4

The outputs (Output mode, Polarity) are controlled via 4 advanced feature

registers (see Table 27: Advanced register: Output control on page 86).

The Polarity field determines whether the output is inverted or not. The out-

put mode can be viewed in the table below. The current status of the output

can be queried and set via the PinState.

It is possible to read back the status of an output pin regardless of the output

mode. This allows for example the host computer to determine if the camera

is busy by simply polling the BUSY output.

Note

Outputs in Direct Mode:

For correct functionality the Polarity should always be set

to 0 (SmartView: Trig/IO tab, Invert=No).

0xF1000320 IO_OUTP_CTRL1 Presence_Inq [0] Indicates presence of this

feature (read only)

PWMCapable [1] All Stingray cameras (housing

and board level):

Indicates if an output pin

supports the PWM feature.

See Table 29: PWM configura-

tion registers on page 89.
