The data pins are routed to PC1-8 (lower 8 bit) and PC12-19 (higher 8 bit), so you probably need to shift your lower 8 bit to the right<<1, and higher 8 bit to the right <<12, and then you can strobe the WR pin. So you will need 3 arduino command for one WR strobe.Like this: REG_PIOC_CODR=0xFF1FE; REG_PIOC_SODR=(VL<<1) & 0x1FE; REG_PIOC_SODR=(VH<<12) & 0xFF000; pulse_WR();For the 4 command pins, they are routed to PD1-4. This should be straight forward.This is possible because the creator of DUE has made perfect routing of these lines to the 2x20 header.SD Card will be directly connected to the SPI interface on the 6pin header in the center of the DUE board(DUE only has SPI access on this 6pin header).Schematic is http://coldtears.lin3.siteonlinetest.com/files/CTE_DUE_shield.zip ]
