From bbb4b9822f094825d7e7fd1f7df716adc2598685 Mon Sep 17 00:00:00 2001 From: Damien George Date: Mon, 10 Apr 2017 17:19:36 +1000 Subject: py/modmicropython: Add micropython.kbd_intr() function. It controls the character that's used to (asynchronously) raise a KeyboardInterrupt exception. Passing "-1" allows to disable the interception of the interrupt character (as long as a port allows such a behaviour). --- py/modmicropython.c | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'py/modmicropython.c') diff --git a/py/modmicropython.c b/py/modmicropython.c index a74e6aa3c..d76706230 100644 --- a/py/modmicropython.c +++ b/py/modmicropython.c @@ -31,6 +31,7 @@ #include "py/stackctrl.h" #include "py/runtime.h" #include "py/gc.h" +#include "py/mphal.h" // Various builtins specific to MicroPython runtime, // living in micropython module @@ -129,6 +130,14 @@ STATIC MP_DEFINE_CONST_FUN_OBJ_0(mp_micropython_heap_unlock_obj, mp_micropython_ STATIC MP_DEFINE_CONST_FUN_OBJ_1(mp_alloc_emergency_exception_buf_obj, mp_alloc_emergency_exception_buf); #endif +#if MICROPY_KBD_EXCEPTION +STATIC mp_obj_t mp_micropython_kbd_intr(mp_obj_t int_chr_in) { + mp_hal_set_interrupt_char(mp_obj_get_int(int_chr_in)); + return mp_const_none; +} +STATIC MP_DEFINE_CONST_FUN_OBJ_1(mp_micropython_kbd_intr_obj, mp_micropython_kbd_intr); +#endif + #if MICROPY_ENABLE_SCHEDULER STATIC mp_obj_t mp_micropython_schedule(mp_obj_t function, mp_obj_t arg) { if (!mp_sched_schedule(function, arg)) { @@ -162,6 +171,9 @@ STATIC const mp_rom_map_elem_t mp_module_micropython_globals_table[] = { { MP_ROM_QSTR(MP_QSTR_heap_lock), MP_ROM_PTR(&mp_micropython_heap_lock_obj) }, { MP_ROM_QSTR(MP_QSTR_heap_unlock), MP_ROM_PTR(&mp_micropython_heap_unlock_obj) }, #endif + #if MICROPY_KBD_EXCEPTION + { MP_ROM_QSTR(MP_QSTR_kbd_intr), MP_ROM_PTR(&mp_micropython_kbd_intr_obj) }, + #endif #if MICROPY_ENABLE_SCHEDULER { MP_ROM_QSTR(MP_QSTR_schedule), MP_ROM_PTR(&mp_micropython_schedule_obj) }, #endif -- cgit v1.2.3
