6 Channel Serializer Board: How to use GPIn as Trigger Input

In order to control the FPGA pin mapping, use the tis-board-ctrl tool that is installed with the driver.

If run without arguments, it shows the current mapping.

For testing the utility, toggle the board LED:

tis-board-ctrl BOARD_LED 1
tis-board-ctrl BOARD_LED 0

In order to manually set gpout1 status to logic 1, and gpout2 status to logic 0, call

tis-board-ctrl BOARD_GPOUT1 1
tis-board-ctrl BOARD_GPOUT2 0

The inputs can also be routed to the trigger pins of the sensors (via FPDLink), if the sensor supports triggering. That is needed for the IP67 housed cameras, because they do not have an extra trigger connector.

For example, this connects GPIN1 to the trigger pin of all cameras:

tis-board-ctrl DESER1_GPIO1 BOARD_GPIN1
tis-board-ctrl DESER1_GPIO3 BOARD_GPIN1
tis-board-ctrl DESER2_GPIO1 BOARD_GPIN1
tis-board-ctrl DESER3_GPIO1 BOARD_GPIN1
tis-board-ctrl DESER4_GPIO1 BOARD_GPIN1
tis-board-ctrl DESER4_GPIO3 BOARD_GPIN1

The outputs can be connected to the sensor's strobe function (via FPDLink), if the sensor supports strobe.

For example, this connects the strobe of the first camera to GPOUT1:

tis-board-ctrl BOARD_GPOUT1 DESER1_GPIO0
