I want to port blimp's osd onto the arm board, do you have specific instructions
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.
I had this board, and I ported the blimp program to this board, and it showed up right.
I will be the airship program port to their own projects, through the debugging of iic, the image display is normal.
But I can't get it to show osd.
Is it because I didn't write spi interface?,
Can osd only be displayed through iic?
I've blocked the SpiTransfer function in adi's code, which displays the blimp tag.So I wonder if I can display characters directly on the screen through iic?
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?
