Hello Weicheng,

Using the software for the eval kit, there is a page called "FPGA Control" under projector control. In this page you will see the "FPGA UHD TPG" section, here is where you can set up the TPG to work without the actuator. You only need to click on the "Set" box for the "XPR OFF 2D TPG" when you have chosen the desired framerate.

Regards,

Oscar

thanks for your reply.

i have tried this way on your reply above, but i cannot see checkboard on DMD although i have set Test Patterns (7-Checkboard) .

i want check I2C_PORT1 : is FPGA and DDP4422 communication?

I2C_PORT2: is XPR Actuator and DDP4422 communication?

pos6:is Actuator Orientation Config , if it effects show image, which one should i choose ? default is Pos6.

FPGA and XPR Actuator communicate by SPI , right?
