Does i.MX RT SDK 2.3 can support CCIR interlace mode function

Danube — Fri, 13 Apr 2018 12:07:09 GMT

Hi ,

We saw i.MX RT SDK 2.3 just only support CCIR Progressive mode base on OV7725 sensor.

Does any CCIR interlace mode example test function code ?

Any S/W program Document ?

Hi Apollo,
Although the CSI module of the i.MXRT series supports interlaced mode, at this time, additionally to the SDK examples, you could also take a look at the following application notes, that use a different camera module:
AN12110: “Developing a Camera Application with i.MX RT Series”.
AN12103: “Developing a simple UVC device based on i.MX RT1050”.

Hope this will be useful for you.
Best regards!
/Carlos

Hi Carlos,

I think i.MX RT default Camera driver is for CCIR656ProgressiveMode

You can see your camera code setting fsl_csi_camera_adapter.c

else if (kCAMERA_InterfaceCCIR656 == config->interface)
{
csiConfig.workMode = kCSI_CCIR656ProgressiveMode;

We don't see any about CCIR656InterlaceMode setting.

Does test any ADV7180 Video decode ic ?

ADV7180 can output CCIR656 interlace mode package.
