Discussion - MCU / Re: FT90x Camera Overwrite read data test pattern

Hello
yes the method for the uncompressed output i want to use but i dont know where to do that. I don't know how to calculate that and where to insert it... I think i was wrong to make changes in the cam_isr function but i don't know.
Thanks in advance for any hint.
Regards twittich

Hello
Thank you for the response.
I know this example and this is running and i'm testing with this. I want to try to inject test data between the input from the camera to the ft90x and the output to usb so that it looks like a testpattern from the camera.
I think i have to make the change in the function "  void cam_ISR(void) "  at  " :"r"(urb->ptr), "r"(&(CAM->CAM_REG3)), "r"(to_read)); "
How can i make red, blue, yellow, green etc bars? Are the values somewhere explained and how the lines are stored so that i can change it, the used format from the camera side is ycbcr422 / yuy2?


Thanks in advance.
Regards twittich

Hello
i'm using the ft90x, the bridgetek example "usbd example uvc webcam" and a camera modul. The camera works nearly fine, just sometimes some fragments in our setup, so i want to inject softwareside data. The idea is where the data is received from the camera i want to fill the bytes manually to make a test picture like colored lines for example.
I don't know where the data is received to overwrite it.
Any one any idea.
Thanks in advance.
