Camera software for FT90x connected to a FT81x
« on: April 09, 2018, 11:36:01 AM »

Hi,
I have purchased the FT90x C compiler  https://www.mikroe.com/mikroc-ft90x from MikroeElektronica along with a 7" display MIKROE-2290 https://www.mikroe.com/mikromedia-hmi-70-cap. The display has a Riverdi 800x480px with a FT813 EVE controller.

My initial goal is to connect a OV7670 camera to the FT900Q micro and display the live video image directly onto the display via the FT813 EVE controller.

The next goal is to then connect a Analog Devices ADV7280A in place of the OV7670 camera. The ADV7280A is a PAL (800*600) 4 analogue input  Video Decoder that simulates a parallel camera. The software will then select the required camera input and display the live feed.

Would you be able to give some assistance with the initial goal of interfacing the camera and feeding the live image directly to the display.
Any generic C code examples of configuring the FT900 and feeding the (BMP or JPG) image to the FT81x would be great.

Thank you,
Neil.

Hi Neil,

We have an example below which takes data from a camera and displays it on the EVE screen. In this case we used an OV5640 camera (from our CleO Camera module). It also includes some optional lines and text overlaid on the image to demonstrate how this can be done. The code displays the image as a series of JPEG images and so could display either JPEG or Bitmap data from other sources.

The code is written for our own FT900 toolchain but could also be used as a reference when porting to other compilers.
