 | | Building a peripheral bus from motor output —
|
| | | Hi all, I recently read an excellent paper by Fred Martin (of MIT fame) on building toys in a modular fashion. His microcontroller was similar to the RCX but had one key addition - a two wire serial bus so that active peripherals could be attached (...) (23 years ago, 25-Aug-01, to lugnet.robotics)

| | | | | (...) Do you have a link to this paper? We are taking a similar approach and using SPI on our JCX controller. We have designed in support for over 20 addressable I/O modules. For example, 4 motors are a module, 8 Lego compatible inputs takes up 2 (...) (23 years ago, 27-Aug-01, to lugnet.robotics)

Is it a Java version of the RCX? Did I miss the link? (...) (...) (23 years ago, 27-Aug-01, to lugnet.robotics)
