Does anyone know what we are doing wrong?
ramDisplayList = RAM_DL; // point to next location
ramDisplayList += 0; // Clear 00100110 -------- -------- -----CST (C/S/T define which parameters to clear)

FT813memWrite32(REG_DLSWAP, SWAP_FRAME); //Make this display list active
All of the registers for this particular piece where checked and the analyzer is receiving what's written however, we believe that we are missing something.
Can anyone help us?
