Read-Only Author L T Posted 20-Apr-2001 07:27 GMT Toolset C166	RE: Then what about interrupt mode? L T Since polled I/O consumes too much of the processor's computing power, can I find some example using buffered interrupt instead?

Eric Juve You need to write your own copy of getkey, and putchar to redirect the printf to the desired I/O port. The c166 toolchain includes a sample for you to modify. By the way they are polled I/O.
