LED 算子

Operator Library: Hardware Platform

The LED operator provides an interface for accessing the board user LEDs of the frame grabber via the applet.

Driving a logic HIGH on the input forces the correspondent board LED to light on. Driving a logic LOW on the input forces the correspondent board LED to light off.

For the exact location of board LEDs on the frame grabber, see the manual of your frame grabber.

On marathon VCX-QP, the numbering of the LEDs is mirrored, see parameter description of parameter Port below.

资源

The operator mirrors the Port parameter settings into the FPGA Device Resources dialog as read-only parameters. You can see the FPGA device resources, if you open the FPGA Device Resources dialog from the Analysis menu. The device resources are read-only:

FPGA Device Resources All Platforms Except imaFlex 2 Dual 100

Figure 438. FPGA Device Resources All Platforms Except imaFlex 2 Dual 100


For the imaFlex 2 Dual 100 platform, the operator is using a read-only resource of type User LED, which is influenced by the Port operator parameter. The User LED resource index is always the Port label value, i.e., USR1 is mapped to the User LED resource index 1 and USR6 to the User LED resource index 6.

imaFlex 2 Dual 100, imaFlex CXP-12 Penta, and imaFlex CXP-12 Quad: {USR1, USR2, USR3, USR4, USR5, USR6}

LightBridge VCL, mE5 marathon VCLx, and mE5 marathon VCL: {USR1, USR2}

mE5 marathon VCX-QP and mE5 marathon VF2: {USR1, USR2, USR3, USR4}

The parameter defines which of the board LEDs will be connected by the operator.

imaFlex 2 Dual 100, imaFlex CXP-12 Penta and imaFlex CXP-12 Quad:

  • USR1 maps the operator to the LED USR1.

  • USR2 maps the operator to the LED USR2.

  • USR3 maps the operator to the LED USR3.

  • USR4 maps the operator to the LED USR4.

  • USR5 maps the operator to the LED USR5.

  • USR6 maps the operator to the LED USR6.

On the imaFlex 2 Dual 100, the board LEDs are located in the following positions:
