(...) So, I finally sat down and figured out how the lnp state machine works in BrickOS. Turns out it was pretty easy to add in a new set of states so it can process a standard OpCode & store the parameters in variables. At this point, I'm not (...)

Hi. (...) That would be a fun state machine to set up... ;-) (...) It only does so when it receives opcodes between 0xf0 - 0xf7 or a standard firmware message (0x55). Of the first eight, only 0xf0 and 0xf1 currently require further action, with 0xf0 (...) (19 years ago, 17-Aug-05, to lugnet.robotics.rcx.legos)

(...) AFAIK there is no way to receive Lego-Messages, except by editing lnp.c and adding that by hand. The only Lego-Messages that brickos knows of, are those from the remote control and the "send message" opcode (0xf7). It may be worthwhile to add (...)

I'm trying to write a BrickOS program that I can use to check the voltage on other RCXs (which use standard firmware). I want to send the Get Battery Power command (0x30 and 0x38), and display the returned value on the display. Can anyone tell me if (...) (19 years ago, 10-Aug-05, to lugnet.robotics.rcx.legos)

(...) I don't think it's a problem with the compiler. There have been changes to the BrickOS code over the years. I know the value sys_time has been replaced with the function Get_sys_up_time().
