Hi,
is there currently any software-support (pbLua, NXT-G, NXJ) for NXT Port4

Thanks for more informations

As far as I know, there isn't any support for this interface in either the
standard firmware or any of the other third party firmware implementations.

The interface runs at 921,600 bps so it will be fast enough to be really useful.

Hi, is there currently any software-support (pbLua, NXT-G, NXJ) for NXT Port4 highspeed serial communication (EIA-485) ? This port can be used for connecting some new hardware (camera, SD-Card-storage) to the NXT... Thanks for more informations Bye (...) (17 years ago, 7-Apr-07, to lugnet.robotics.nxt)
