Hi Ralph, we are using this code: collectgarbage( "setpause", 110 ); function setupI2C(port) nxt.InputSetType(port,2) nxt.InputSetDir(port,1,1) nxt.InputSetState(port,1,1) nxt.I2CTimer(3) nxt.I2CInitPins(port) end function ReadPCF(port) (...)

(...) Hi there, Thanks for venturing those reasons. I had been thinking that with the release of the NXT firmware that there may be options to compile code that worked directly with the firmware. Cheers (18 years ago, 19-May-07, to lugnet.robotics.nxt.nxthacking)

(...) Hi Thanks for the fast response, I think I'll have a look at the pbLua firmware. What I am working towards is a method of running Haskell programs on the NXT by converting to C bytecodes first. (18 years ago, 19-May-07, to lugnet.robotics.nxt.nxthacking)

(...) I suspect it could, but I'm not sure that's an approach you want to take. For one thing, there's the question of how to address and handle all the special HW that is attached to the ARM inside the NXT... and furthermore communicate with the (...)

(...) There's no reason you can't compile straight ANSI C and run it on the NXT. I was doing it last year and ran an ATMEL sample program that turned the NXT into the world's most expensive 256K (not M) Flash drive :-) The hard part is using the (...)

Hi there: I've been trying to find a method of coding the NXT using C, however the existing languages available, such as RobotC, or NBC/NXC etc all seem to be C-like languages and not ANSI C. This seems to be the trend, but does anyone know why (...) (18 years ago, 19-May-07, to lugnet.robotics.nxt.nxthacking)

(...) There are no hidden commands, but if it's ABSOLUTELY necessary I can add peek and poke for bytes, words and longs. This may be more dangerous than it's worth :-) What hardware do you need access to? Ralph (18 years ago, 19-May-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)

(...) 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 (18 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 (18 years ago, 18-May-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)

Hi, has anybody successfully tried to read ports from I2C connected PCF8574 with pbLua (Beta-8) ? Writing and setting ports is no problem, but reading ports fails. The return value is every times 0 (not NIL) Any idea ? Thanks in advance Bye (...) (18 years ago, 18-May-07, to lugnet.robotics.nxt, lugnet.robotics.nxt.nxthacking)
