Anyone got a link to the datasheet(s) for the H8 in the RCX? For example, the pinout of the thing. And details like how large the address space is. Also, does anyone have a "Memory Map" for the current RCT (i.e. this address range is ram, this (...) (22 years ago, 6-Nov-03, to lugnet.robotics)

(...) Now this is a good idea. Basicly, a small simple socket that exposes the data bus, address bus and also some control bus lines (like Read/Write or whatever else is needed) plus power (obviously) would be perfect. One would need to have (...) (22 years ago, 6-Nov-03, to lugnet.robotics)

Here is the perfect idea: Basicly, the new RCX comes with several components: 1.sensors, motors and so on as now (perhaps with some new ones) 2.a large "base unit" that would have a good CPU, communication with the host PC for programming, LCD (...) (22 years ago, 6-Nov-03, to lugnet.robotics)

(...) Yes. I'm running MacNQC on a G4 Powerbook with the USB tower - no complaints. I should add, however, that I migrated to MacNQC after installing Robolab (a LEGO product, sold on the educational market), so that likely set up the drivers for the (...)

In practice, recovery from slew errors is significantly more difficult with a location grid-based mapping instead of an obstacle-based (...) (22 years ago, 5-Nov-03, to lugnet.robotics)

It does so until the last button is released, at which time (...) (22 years ago, 5-Nov-03, to lugnet.robotics)

Ok, here’s my dilemma: I have a Compaq Ipaq 3835, RCX 1.5, Lego remote, and PDAwin learning remote control on Ipaq, and VitoTechnology o-Scope software (IR scope on the Ipaq). I had both pieces of software learn the “beep” command from the Lego (...) (22 years ago, 5-Nov-03, to lugnet.robotics)

Hi A while ago I looked at using IC for writing programs. At the time there were 2 major turnoffs. There was no support for rotation sensors and you needed to own one of the serial infrared towers. It was easy to install and it had its own firmware. (...) (22 years ago, 5-Nov-03, to lugnet.robotics.rcx, lugnet.robotics.rcx.legos, lugnet.robotics.rcx.java)

I am fairly new to Lego Mindstorms so forgive me if I end up beating a dead horse. I have a RIS 2.0 kit which, as you all know, comes with the USB tower. I plan on using MacNQC to code. Is it possible to do everything (code and transmit finished (...) (22 years ago, 5-Nov-03, to lugnet.robotics)

Both methods have their place. There are pro's and con's to each. For John's purposes, his approach is quick, easy, and requires very little programming to use. That would leave him free to focus on other programming he's more interested in. The (...) (22 years ago, 5-Nov-03, to lugnet.robotics)

(...) I believe that is exactly what legOS does. It compiles your program and stores it in the firmware area. legOS has no firmware, and it ignores the ROM code, too. It accesses all the hardware directly. That's my understanding, at least. (22 years ago, 5-Nov-03, to lugnet.robotics)
