port blimp's osd onto the arm board

Hi,

You have the OSD API functions in Blimp_ADV7625_Framework_User_Manual.pdf. Please refer here https://ez.analog.com/video/w/documents/707/blimp-osd-designer-tool-for-naturevue-adv800x-and-advantiv-adv7625

 Do you have one of our evaluation board? If so,load our application binary,there you have the inbuilt demo OSD at https://ez.analog.com/video/w/documents/698/advantiv-eval-adv7625-smz-video-evaluation-board

And also it seems like duplicate of this thread at ez.analog.com/.../adv7625-ported-to-arm-board

Please do not create duplicate thread since it would be difficult for tracking.

Thanks very much for understanding.

Thanks,

Poornima

Sorry, I just want people to answer my question as soon as possible, so I made two posts

Thank you very much for your reply.

Hi,

 For OSD, We need both i2c and Spi interface, Characters cannot be displayed only with i2c.

Thanks,

osd is initialized by ADIAPI_OsdConInit,
The switch is then controlled by ADIAPI_OsdKeyPress.
I blocked the Spi related function in ADIAPI_OsdConInit, and the blimp control I defined is still displayed (in advantiv-eval-adv7625-smz-video-evaluation-board).
So, if I'm going to implement osd display, where is my spi function going to be implemented?Not in the ADIAPI_OsdConInit function?

Now that my image is out, I can use the iic control to have it display some blocks.If I want to implement spi, I need to implement SpiTransfer in the ADIAPI_OsdConInit function, right?

Hello!

I think you use （OSDAPI_RegisterSpiI2cHal(SpiTransfer, I2c0WriteRegister8, I2c0ReadRegister8, I2c0Read2Register8, SpiSetSlave);） this function to call spi function. I have shielded SpiTransfer from your code, but several labels can still be displayed normally.

Thank you very much for your answer.

Yes. You need to implement the SpiTransfer function.

I have shielded SpiTransfer from your code, but several labels can still be displayed normally.

If you block the SPI functions, label will not be displayed correctly. Can you try power cycle the board and check again and see labels are displayed correctly with demo board.

Please let us know if you are seeing any issues after adding SPI functions.

Thanks,

hello

As shown in the figure below, I removed your flash and then removed the spi function.
