I started to learn the Internet of Things and shared some ideas with you. I also urged myself to work hard ᕦ(・ㅂ・)ᕤ
I learned CC2530. The first lesson started with simple lights!
principle
This is mainly through P1DIR (0xFE), which is the input and output
setting register of P1 port. 0: input, 1: output .
the code
#include <ioCC2530.h> //把 CC2530 的头文件包含进来
#define uint unsigned int
#define uchar unsigned char
//定义控制灯的端口
#define YLED P1_0 //定义 YLED 为 P10 口控制
#define BLED P1_1 //定义 BLED 为 P11 口控制
//函数声明
void Delay(uint); //延时函数声明
void InitIO(void); //初始化函数声明
/****************************
//延时
*****************************/
void Delay(uint n)
{
uint i,j;
for(j = 0; j<5; j++)
{
for(i = 0;i<n;i++);
} }
/****************************
//初始化程序,将 P10、P11 定义为输出口,并将 LED 灯初始化为灭
*****************************/
void InitIO(void)
{
P1DIR= 0x03; //P10、P11 定义为输出
BLED = 1;
YLED = 1; //LED 灯初始化为灭
}
/***************************
//主函数
***************************/
void main(void)
{
InitIO();
while(1)
{
for(int i=0;i<5;i++)
{
YLED = 0;
Delay(5000);
YLED = 1;
Delay(5000);
}
for(int i=0;i<5;i++)
{
BLED = 0;
Delay(5000);
BLED = 1;
Delay(5000);
}
for(int i=0;i<5;i++)
{
BLED = 0;
YLED = 1;
Delay(5000);
BLED = 1;
YLED = 0;
Delay(5000);
}
} }
