Slow frame rate (DE1 + D5M)

I connected the d5m camera to the de1 board and loaded the DE1_D5M project. When I plug the vga connector I can see images, but with a very slow rate. If I increase it (sw0 + key1) the image quickly ...

Has anyone solved this problem?

I too have a slow frame rate with D5M and DE1

You need just increase the PIXCLK by adjusting the d5m build-in PLL, or connect XCLKIN pin directly to your in-fpga PLL.

In terasic examples XCLKIN is set to 12MHz thru d5m's PLL, but PIXCLK has the same frequency(because of wrong config(I2C_CCD_Config.v))

Example of PLL configuration is in THDB-D5M_Hardware specification.pdf (pages 30-32)
