		Enhanced standard NXT firmware
Over the past couple days I have used the IAR Embedded Workbench to implement some enhancements and bug fixes for the standard NXT firmware. The bug fixes are as follows: 1. RIC drawing code incorrectly checked the size of the OP_LINE structure for (...) (18 years ago, 16-Mar-07, to lugnet.robotics.nxt.nxthacking, lugnet.robotics, lugnet.robotics.nxt)

		The standard NXT firmware & the case of the missing opcodes
There are several opcodes defined in c_cmd_bytecodes.h which are missing from the VM implementation in c_cmd.c Here are the ones that are not implemented: //Family: Bit manipulation #define OP_CMNT 0x0A // dest, src #define OP_LSL 0x0B // dest, src (...)

		More firmware enhancements
I have implemented OP_WAIT and a variant of OP_WAIT which takes a variable rather than an immediate numeric value (which in nbc is called "waitv"). I also modified NBC to accept a command line switch that tells it whether the firmware supports waits (...) (18 years ago, 22-Mar-07, to lugnet.robotics.nxt.nxthacking)

		Re: ARM Assembly Language Programming on NXT?
Hi Juergen, Thanks for replying. (...) Thanks for the info. My goal is to run and debug ARM assembly language programs executing in RAM. I was not familiar with the NXT, so currently I'm looking at the on-board capabilities. I realized after some (...) (17 years ago, 16-Oct-07, to lugnet.robotics.nxt.nxthacking)
