Adrf 6518 - VGA

UThe vga are present on the front side 

And 

Those two. 

Measuring whether I can see if VGA works properly. Will need to revise spectrum analyser today. 

Setting the dac voltages to - 

100/200/300 since 1v is the max ...as seen in the data sheet - 

Use trig menu and vertical and horizontal knobs to adjust 

So reset doesn't work ! 

Le is fine - data is corrupted ! 

Click seems okay. !! 

If I program all zeros - I get lower power consumption - that's a plus 

I have forgotten how to check back end codes ! Sigh. This is going to be a long night. Okay- focus - peace. Play music and move on. 

Okay. The basic mistake I was making was that the function for transfer of bits was from msb to lsb. But the VGA protocol is lsb to msb! 

Hence I played with Matlab and re arranged the bits to make it work. 

When I pass- I pass based on the register protocol in the data sheet 

If you notice - the b0 was not mentioned in the data sheet directly... But flip the pages to read the programming part and you will see that b0 is actually specifying reading and writing bit. It needs to be one for writing. 

So VGA done !! 

Awesome :)
