I made something similar to a dio_ implementation for the CBM web server
of Contiki, but I'm not sure if it is useful or not. In any case, it is
far from complete, but I could probably turn it into a CBM dio if people
would be interested in this?
It currently is very ineffcient as well, I suppose, as it is implemented
using disc commands in a very kludgy fashion. Like this:
void
read_sector(u8_t device, u8_t track, u8_t sect, void *mem)
{
int ret;
cbm_open(15, device, 15, NULL);
cbm_open(2, device, 2, "#");
sprintf(cmd, "u1: 2 0%3d%3d", track, sect);
cbm_write(15, cmd, strlen(cmd));
ret = cbm_read(2, mem, 256);
cbm_close(2);
cbm_close(15);
}
... but without actually using the sprintf() call but a direct buffer
manipulation hack.
Would something like this be of any value at all?
Cheers,
