You might want to take a look at saicanon - the standalone interpreter. G-code is actually a lot more complex than you think. An ATMEGA or XMega can generate steps as necessary (though even that isn't as simple as it sounds), but the G-code interpreter has to deal with loops, conditionals, variables, machine control (tool changes, coolant ...), machine state, etc. The way EMC2 does all this is to have the high level interpreter translate to an intermediate state, called "canon" (the canonical machine commands or similar). Those calls are the motion primitives needed after all variable and equation evaluation. (G-code has many floating point math functions, in case you didn't know :) ) You might want to make a motion and IO controller rather than a g-code interpreter. The motion commands should be sent from the task controller (which includes the interpreter) to the motion and IO controllers via NML. NML can use a serial transport, but I'm not sure if that code has been maintained (or even included with EMC2 - it was part of the original rcslib). - Steve ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
