- is anyone out there using Klaus Pedersen's SCSI driver code for the TT?
- i've modified it slightly to work under Lattice C 5.5 but it's giving
- me a hard time.
-
- the assembly routine that selects the SCSI device always times out, no
- matter how long a timeout period i give it. about a year ago i wrote my
- own code to drive the SCSI bus in C, but it doesn't do DMA transfer
- properly and needs to handshake data across. when we found Klaus' code
- we were quite pleased.
-
- the thing that absoulutely killed the speed on my C routines was the
- device selection. it had to waste a lot of time just sitting in delay
- loops. Klaus' code is much more elegant about this, but it also
- appears to not work on our machine.
-
- any help or comments would be appreciated
- thanks in advance
