基于電子積木arduino的G代碼解釋器原代碼，來源于http://arduino.cc/forum/搜CNC
我去年收集了許多程序，經(jīng)過測試挑選出可以用，后來沒時間繼續(xù)研究學(xué)習，現(xiàn)在發(fā)
上來給有用的朋友參考
下面是其中的小段源碼
//init our variables
long max_delta;
long x_counter;
long y_counter;
long z_counter;
bool x_can_step;
bool y_can_step;
bool z_can_step;
int milli_delay;
void init_steppers()
{
//turn them off to start.
disable_steppers();

//init our points.

current_units.y = 0.0;
current_units.z = 0.0;
target_units.x = 0.0;
target_units.y = 0.0;
target_units.z = 0.0;

pinMode(Z_DIR_PIN, OUTPUT);

pinMode(Z_MIN_PIN, INPUT);
pinMode(Z_MAX_PIN, INPUT);

//figure our stuff.
calculate_deltas();
}
void dda_move(long micro_delay)
{
//enable our steppers
digitalWrite(X_ENABLE_PIN, HIGH);
digitalWrite(Y_ENABLE_PIN, HIGH);
digitalWrite(Z_ENABLE_PIN, HIGH);

//figure out our deltas
max_delta = max(delta_steps.x, delta_steps.y);
max_delta = max(delta_steps.z, max_delta);
//init stuff.
long x_counter = -max_delta/2;
long y_counter = -max_delta/2;
long z_counter = -max_delta/2;

//our step flags
bool x_can_step = 0;
bool y_can_step = 0;
bool z_can_step = 0;

if (micro_delay >= 16383)
milli_delay = micro_delay / 1000;
else
milli_delay = 0;
