Hello everybody,
I try to program the RCX at low level. I want to be able to program
using the Hitachi h8/3292 directly. For example, I want to use the
free-running timer, define own interrupt handlers and so on. In fact, I
*really* need to control the timer (this is for educational purpose).
My tries so far leads to failures... I tried using Quite C and libRCX,
but I think I have to shortcut some ROM routines (particularly the
init_timer routine).
Can anyone give me a tip about controlling Hitachi free-running timer
directly ? Thanks.
