I have chased this topic around quite a bit in the last couple of years and built a few prototype devices to perform "I/O expansion". My final conclusion, having gone to the trouble of building a device which permits two of the RCX motor ports and (...) (23 years ago, 5-Jul-02, to lugnet.robotics)

Hi, since a few hours, I'm trying to give an RCX another LNP_HOSTADDR - so I changed the appropriate line in boot/config.h from #define CONF_LNP_HOSTADDR 0x00 //!< LNP host address to #define CONF_LNP_HOSTADDR 0x01 //!< LNP host address and compiled (...)

(...) My original idea is to switch a 12 - 14 V, 250 mA (Conrad) infrared beamer using my RCX's motor output. But it would be nice to be able to build a kind of universal switch for controling other devices. Thanks in advance! Remko (23 years ago, 4-Jul-02, to lugnet.robotics)
