i'm trying to display a visual output by using

TVP5150AM1 Decoder and STM32F429II MCU.

Is it possible to get CCIR656(TVP5150AM1) format with DCMI(STM32F429II) input? (On manual it's possible)

If it is, How do I configure the settings of

DCMI_ESCR register and DCMI_ESUR register?

Visual format is NTSC 720*480, CCIR656(Embedded data synchronization mode).

If there are any reference manual or data, please inform me.

Hello,

'TVP5150' Decoder is working in mode ITU656 and it's possible to get CCIR656 fromat with DCMI input.

As described in the RM0090, page 463: DCMI Interface is configured in Snapshot mode and to use Embedded data synchronization mod: Mode 1 An alternative coding is the camera mode 1. This mode is ITU656 compatible.

Make a search in the Forum with keywords: TVP5150, ITU656, DCMI_ESCR, DCMI_ESUR, DCMI..., maybe you will find several threads on the topic that helps you on the configuration settings.

Regards
