(...) Speaking of Quite C, I am working on figuring out a good way to integrate Quite C into the BricxCC system. It is a bit different from the other languages BricxCC supports in that you compile to an SREC and download it as a new firmware rather (...) (21 years ago, 12-Sep-03, to lugnet.robotics.rcx)

(...) Quite C is your best place to start with a language. C can give you direct access to the timer. The timer is considered an I/O device, but all I/O on the H8 is memory mapped. Having said that, if you know the address of the timer, you can (...) (21 years ago, 12-Sep-03, to lugnet.robotics.rcx)

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 (...) (21 years ago, 12-Sep-03, to lugnet.robotics.rcx)

Hi, (...) I'm having a bit of difficulty to understand what you are trying to do, as I know Lejos but not the DCC/train side of things. In particular, on which side do you want to use Lejos, sending those remote commands from an RCX or from a PC? (...) (21 years ago, 12-Sep-03, to lugnet.robotics.rcx.java, lugnet.trains)

(...) Old thread, but oh, well. 4800 baud is 4800 bits per second or 600 bytes per second. If you assume 50% overhead, which is optimistic, that's 300 bytes per second. So I think anything over 200 bytes per second is pretty good. (21 years ago, 12-Sep-03, to lugnet.robotics.rcx.legos)
