CC3220S-LAUNCHXL: TI Drivers

Part Number: CC3220S-LAUNCHXL
Other Parts Discussed in Thread: CC3220S, CC3200

Dear,

For a hobby project of mine i'm using a OV7670 camera module. I want to make this work using the CC3220S-LAUNCHXL. I saw that the CC3220S chip has a build in parallel camera interface.

Following the TI driver website I found that i had to implement the camera attributes myself. So when I had done that I began testing. Unfortunatly not to a satisfactory manner. The camera module needs a external clock. Luckily the CC3220S has a build in clock oscillator especially designed for the use of a camera. The datasheet of de CC3220S states that Pin 2 is responsible for the output of this high frequency clock signal. Unfortunatly I can't make Pin 2 output this clock signal. I have removed the jumpers J15 & J16, because Pin2 is connected to the I2C bus via these jumpers.

Below you will see the changes I've made to the CC3220S_LAUNCHXL.c file.

I hope you can point out where I've made the mistake.

Kind regards,

Erwin

    Hi Erwin,

    There is a reason we do not have the camera interface already integrated into TI Drivers, and that is because we do not support this interface even though it is in hardware. If you want to pursue this you will be on your own essentially. That said you would probably do best by starting with the camera examples in the CC3200 SDK (driverlib) rather than trying to incorporate into TI drivers immediately.

    Dear _aaron,

    In the TI drivers API (see picture below) you can see that there is a Camera.h file. Doesn't that mean there is also softwaresupport for the CC3220S for using a camera?

    Unfortunatly I can't find any example code where there is made use out of the Camera library.

    I'm afraid I'll have to cut my loses.

    Kind regards,

    Erwin

    Hi Erwin,

    Again, there is no support for this interface with those devices despite the presence of a header file
