grbl 0.9j for stm32f103 master源码

在github上找的grbl stm32版本

单片机源程序如下:

#include "project_include.h"
#include "grbl.h"
// Declare system global variable structure
system_t sys;
int main(void)
{
JTAG_Set(SWD_ENABLE); //JTAG接口状态设置
delay_init(); //延时初始化
// Initialize system upon power-up.
serial_init(); // Setup serial baud rate and interrupts
settings_init(); // Load Grbl settings from EEPROM
stepper_init(); // Configure stepper pins and interrupt timers
system_init(); // Configure pinout pins and pin-change interrupt
memset(&sys, 0, sizeof(system_t)); // Clear all system variables
sys.abort = true; // Set abort to complete initialization
sei(); // Enable interrupts
// Check for power-up and set system alarm if homing is enabled to force homing cycle
// by setting Grbl's alarm state. Alarm locks out all g-code commands, including the
// startup scripts, but allows access to settings and internal commands. Only a homing
// cycle '$H' or kill alarm locks '$X' will disable the alarm.
// NOTE: The startup script will run after successful completion of the homing cycle, but
// not after disabling the alarm locks. Prevents motion startup blocks from crashing into
// things uncontrollably. Very bad.
#ifdef HOMING_INIT_LOCK
if (bit_istrue(settings.flags,BITFLAG_HOMING_ENABLE)) { sys.state = STATE_ALARM; }
#endif
// Force Grbl into an ALARM state upon a power-cycle or hard reset.
#ifdef FORCE_INITIALIZATION_ALARM
sys.state = STATE_ALARM;
#endif
// Grbl initialization loop upon power-up or a system abort. For the latter, all processes
// will return to this loop to be cleanly re-initialized.
for(;;)
{
// TODO: Separate configure task that require interrupts to be disabled, especially upon
// a system abort and ensuring any active interrupts are cleanly reset.
// Reset Grbl primary systems.
serial_reset_read_buffer(); // Clear serial read buffer
gc_init(); // Set g-code parser to default state
spindle_init();
coolant_init();
limits_init();
probe_init();
plan_reset(); // Clear block buffer and planner variables
st_reset(); // Clear stepper subsystem variables.
// Sync cleared gcode and planner positions to current system position.
plan_sync_position();
gc_sync_position();
// Reset system variables.
sys.abort = false;
sys_rt_exec_state = 0;
sys_rt_exec_alarm = 0;
sys.suspend = false;
sys.soft_limit = false;
// Start Grbl main loop. Processes program inputs and executes them.
protocol_main_loop();
}
}
