Reading RAM_G back out

[vbb]

Is there a way to read the RAM_G back out again? 

I see there is a private rd_n() which is also used in void GDClass::get_inputs(void) {

I exposed rd_n as public in the library but it didn't seem to fill with the graphics data with the call

GD.rd_n(0, buf, 100);

It's my first day with the GD3 so maybe I missed something with respect to setting up the command stream for reading or something.


Cheers,

OK.. so I found my problem. I had to use GD.finish(); assumedly to execute the previous commands and write the data to be able to read it.

GD.finish();
GD.rd_n(0, buf , 100);

Excited.. I can now progress.

Glad you found it.

Yes, to explain for the next person. Like OpenGL EVE buffers commands, so when doing a read back you have to wait until it has "caught up". GD.finish() is just like glFinish().
