I have used the reference code sent me to update the registers of AD9970.
It is working but with the wrong Horizontal and vertical timing.
I have tried to modified the Horizontal and vertical timing by writing to 0x800 to 0x81f but without any luck.
If it is possible, please give me a simple example of register setting since the explanation inside AD9970 datasheet is not clear and even the 0x810 to 0x81f don’t exist inside manual.
- Regarding to 0x800,
how to set up the rise position and how to set up the fall position.
- Should I use PBLK,
HBLK and CPBLK all or only need to use HBLK and CPBLK?
- I have implemented three sync words, but they are out one by one at beginning of the line . For example, first line has sync word one and few lines later, sync word 2 at the beginning of the line, etc.
Many thanks for your helps.
