Hello,
I have been having trouble getting my camera to run at 60 fps at VGA resolution. The camera's clock is getting to set to 24MHz instead of 27MHz and I'm not sure where to correct this. Also, I already adjusted the sensor's driver to the minimum horizontal and vertical blanking. This change got me close 60, but its only at 56-57.
One last question, is there a way to get significantly more frames per second out of this camera than 60? For example, by lowering the resolution to 320x240?
Thanks,
Nate
The clock is from DM365 CLKOUT0, which is derived from DM365 clockin (24Mhz). Although there is PLL's in the DM365, unfortunately, CLKOUT0 can only be lower than clockin (please refer to DM365 datasheet).
you could use an external 27Mhz OSC, but that requires hardware change.
Another thing you could try, is to reduce the actual output size to VGA. you know, the sensor is WVGA (752x480), if you change the active column size to 640, it may get higher frame rate.
at 320x240, it can run up to 120fps (with 27Mhz input).
Hey Nate, did you get this camera working under the 2.6.32 kernel? If so, where did you get the driver?
I would also be interested to know if you got the LI-VM34LP working under the 2.6.32 kernel. And if so, could you point me in the direction to get started?
