STM8L15x for IAR点亮LED-电子工程世界

分享到: 微博; QQ; 微信; LinkedIn

一、电路分析

STM8L151G6U6 的LED有两个，分别是：LED1：POWER_LED ---- PB1 ；

LED2：STATUS_LED ---- PB2

二、IAR新建工程准备

1.在项目文件夹里创建3个文件夹

2.fWLIB用来存放stm8板子的各种配置头文件和.c文件

3.project用来存放工程文件和debug日志

三、新建工程

1.Create New Project

2.选择工程模板------c，将工程命名为led，将工程文件保存在project下

3.addd flies

四、配置选项卡

1.右键选项

2.GO --->target

3.GO----->library C

4..GO----->library O

5.C/C++---->Optimitions 代码的优化

6.C/C++---->preprocessor

$PROJ_DIR$ 表示用户建项目的当前目录，途中显示的有stm8115x_conf头文件在项目中会使用，如果不把用户文件夹包含进来会报错显示找不到stm8115x_conf.h头文件。

$PROJ_DIR$..Fwliblibraryinc

$PROJ_DIR$..user

$PROJ_DIR$..FWlibinc

$PROJ_DIR$..FWliblibrarysrc

7.Output converter 设置输出的可执行文件的形式，通常有hex和bin两种形式:

8.设置下载工具的类型，STM8可以支持串口下载（比较麻烦！）和ST-LINK下载,我们用ST-LINK下载

五、代码的编写

1.main.c

#include "stm8_board.h"

#include "timing_delay.h"

int main( void )

{

turn_led(LED_STATUS, OFF);

}

2.led.c

STM8L15X液晶初始化程序

再次用到了STM8L15X的液晶功能，有几点要注意的。 1. LCD可以配置成内部的，也可以配置成外部的。内部的可以调整，开起来会更灵活一点。但是要注意： 1）低功耗模式，无法使用内部电压，因为内部电压的电路会增加CPU电流，所以如果启用了低功耗模式，采用内部电压供电给LCD，那么是点不亮的。 2）如果采用外部电压供电，VLCD引脚不能接外部电压，只能接1uF或其它参数电容，否则也点不亮。 2. 注意以上内容，基本可以点亮LCD。至于怎么让LCD显示得正确或者更清晰则要根据LCD参数设定相关参数了。 void LCD_GLASS_Init(void) { // unsigned char i; /* Enab
