| (...) Hi, we solved the problem... Lego-Firmware has own brain and handle read/write with own mechanisms ;-( The last read/write bit is handled automatically by lowlevel routines. Reading the same address like writing solves the problem. (...) (19 years ago, 21-May-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)

| Hi Ralph, times ago, you have added the function to power off the NXT by pressing the orange button... But: what about implementing a function to break every running code and return back to interpreter ? It is very useful for debugging and (...) (19 years ago, 19-May-07, to lugnet.robotics.nxt)

| (...) No ideas yet, Christian. I do have a Mindsensors kit here to look at over the weekend. Are you SURE you are sending the correct string to read the registers? Can you post the code you're using for the test here? Cheers, Ralph (19 years ago, 19-May-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)

| Hi, is there a way to access the NXT-hardware directly with pbLua ? Are there any hidden commands to allow this ? Any idea ? Thanks in advance Bye Christian (19 years ago, 18-May-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)
