STM32 Keil C + + writing microcontroller program

C + + belongs to the object-oriented programming language, the idea of OOP is needless to say, especially for complex software engineering, using OOP is definitely a multiplier, relative to the traditional C;

Of course, c to write a single-chip computer program is understandable, has continued a tradition, from the beginning of college to work, many people have been using C to do, but since Keil support C + + compilation,

You can use C + + to write your code, you can use the high-level language to structure, clear your program, why not? Haha, personal opinion! Below to get to the chase:

C + + compatible, so STM32 library can be used by C + +, in this case, it is simple! In the establishment of a new STM32 project, it is possible to direct C + + programming;

Using the C + + way to build a good file, I wrote a demo:

. h file--#ifndef __pled__#define__pled__#include"stm32f10x.h"classpled{ Public: PLed (); ~PLed ();  Public:        voidLed_gpio_config (void); voidTurnOn (uint16_t Port,BOOLstatus); Private:};#endif. cpp Files--#include"PLed.h"PLed::P LED () {led_gpio_config ();} PLed::~PLed () {}voidPled::led_gpio_config () {gpio_inittypedef gpio_initstructure;                                                                    Rcc_apb2periphclockcmd (Rcc_apb2periph_gpioe, ENABLE); Gpio_initstructure.gpio_pin= gpio_pin_6|gpio_pin_5; Gpio_initstructure.gpio_mode=gpio_mode_out_pp; Gpio_initstructure.gpio_speed=Gpio_speed_50mhz; Gpio_init (Gpioe,&gpio_initstructure);          Gpio_setbits (gpioe,gpio_pin_5); Gpio_setbits (Gpioe,gpio_pin_6); }voidPled::turnon (uint16_t Port,BOOLstatus) {  if(status) gpio_setbits (Gpioe,port); ElseGpio_resetbits (Gpioe,port);}

Main file--#include"stm32f10x.h"#include"misc.h"#include"stdio.h"#include"PSysTick.h"#include"PLed.h"intMainvoid) {Psystick PST; Pst.    Systick_init ();        PLed PLed;  while(1) {pled. TurnOn (Gpio_pin_5,true); Pled. TurnOn (Gpio_pin_6,false); Pst. Delay ( -); Pled. TurnOn (Gpio_pin_5,false); Pled. TurnOn (Gpio_pin_6,true); Pst. Delay ( -); }}

Systick file #ifndef __pdelay_h#define__pdelay_h#include"stm32f10x.h"classpsystick{ Public: Psystick (); ~Psystick ();  Public:        voidDelay (u32 ntime); voidSystick_init (); Staticu32 Timingdelayx;};#endif#include"PsysTick.h"Psystick::P Systick () {}psystick::~Psystick () {}voidPsystick::D elay (u32 ntime) {Timingdelayx=Ntime;  while(Timingdelayx! =0);}voidPsystick::systick_init () { while(Systick_config (Systemcoreclock/ +)); }u32 Psystick::timingdelayx=0;

Interrupt Function: extern " C " {void systick_handler (void) {    if(psystick::timingdelayx!= 0x00 )    {      Psystick::timingdelayx--;    }     Else         pusart::senddata ('E');}}

The entire project C + + code as above, directly to compile, of course, if your main is still used. C, can also not modify the suffix, directly in the properties of the MAIN.C modified to C++sourcefile can be used in the interrupt file, the interrupt file is also changed to C + + type,

After this compilation, and normal C writing, download files to a single-chip computer can be;

It's almost done! After the problem, continue to study!
