Control exposure time and gain with FPGA as frame grabber

Question

Hi,
I'm using a Basler acA2000 340kc camera with a PCIe1473R FPGA as frame grabber.
I managed to obtain images succesfully by modifying some of the sample codes. I can also control some of the camera settings thorugh the Pylon software.
Nevertheless, I'd like to control the exposure time and gain in   LabView.
Any idea on how to do this?
Thanks

Ultimate the serial port on the board is controlled by the code on the FPGA. There are shipping examples that provide the FPGA-side implementation of interfacing the serial port to a host-side interface, which then bridges it to a TCP port, which is bridged to a DLL called "clsernif.dll", which interfaces through the common "clallserial.dll" that Pylon can use to access the camera.
Depending on your needs, you could interface at any of these layers.
-If you need to do this with the ultimate in determinism, you could have the FPGA issue these serial commands directly as needed
-If can do it from the host CPU, you could modify the host-side code and send/receive serial traffic to the FPGA code directly
-You could examine the example code that bridges to a TCP port and simple write some host VIs that talk directly to it by opening a TCP session to the socket it uses.
