i use the c6711 dsk. i have a usb daughtercard, but i
cant find a possibility to write direct to address and
data lines and read from the data lines. the
daughtercard connects data lines from 0:15 on the J
connectors of the dsk. also address lines. how do i
use a CE space?
Thanks
Semmel

Hello Semmel,
To "use CE space" refer to the addresses:
0x8xxxxxxx CE0 - DSK SDRAM
0x9xxxxxxx CE1 - DSK SW&LEDs + FLASH 0xAxxxxxxx CE2 - daughtercard
for DSK 0xBxxxxxxx CE3 - daughtercard for DSK
Replace the 'xxxxxxx' with 7 hex digits that you want to see on
the address lines.

thanks.
And how can i send "commands" on the data lines. e.g.
i have to send commands via the ED[0:7] and read data
from ED[0:15]. is this also possible with CE2?

Semmel,
A lot of this has to do with your hardware.
All that you have to do is to treat your I/O registers as memory addresses.
If you need to store command 0xAB at address 0xA0000004, just store it as if it
were memory. The same for reads [except that you will want to read shorts
instead of chars]
