Hello  !

 

I started to work with the demo board of ADV7842 & 7511.

My interrest is in the Graphics mode with the VGA port.

 

I wonder how to make a script for the 1680x1050@60 mode .

I try to match the values of the 1400x1050 mode to my mode but i don't know how to adjust the values of

DE_H_START, DE_H_END, FR_LL.

 

Is there a way to calculate this value ?

 

For the other value like CP_START_VBI_CP_END_VBI, L_COUNT_MAX i set them from the BTF calc sheet from The VESA.ORG.

 

thanks
