Hi, I'm having trouble getting my fast read and write strobes out of a AN2135 EZ-USB device. I don't have the code in front of me, but this is basically what I'm doing (note I've set up the ports correctly to drive the read/write strobes). All of the documentation I've seen has been in assembly, so I'm wondering if I'm missing something in the translation to 'C'. I'm trying to do this for bulk transfers... Thanks! xdata BYTE ext_data; // generate fast read: // point to InBuf1 AUTOPTRH = 0x7E; AUTOPTRL = 0x80; AUTODATA = *ext_data; // generate fast read // generate fast write: // point to OutBuf1 AUTOPTRH = 0x7E; AUTOPTRL = 0x40; AUTODATA = 0xFF; // write temp output data *ext_data = AUTODATA; // generate fast write
