以下是nrf24l01无线发送接收51单片机程序示例,供参考:
发送端程序:
```c
#include <reg51.h>
#include "nrf24l01.h"
unsigned char code addr[5] = {0x34,0x43,0x10,0x10,0x01};
void main()
{
unsigned char data1[5] = {0x5a,0x5a,0x5a,0x5a,0x5a};
unsigned char status;
nrf24l01_init(addr);
while(1)
{
nrf24l01_send(data1);
status = nrf24l01_read_reg(STATUS);
if((status & 0x30) == 0x20)
{
nrf24l01_write_reg(STATUS,status & 0x30);
P2 = ~P2;
}
}
}
```
接收端程序:
```c
#include <reg51.h>
#include "nrf24l01.h"
unsigned char code addr[5] = {0x34,0x43,0x10,0x10,0x01};
void main()
{
unsigned char data1[5];
nrf24l01_init(addr);
while(1)
{
if(nrf24l01_receive(data1))
{
P1 = data1[0];
}
}
}
```
这里的nrf24l01.h和nrf24l01.c是nRF24L01模块的驱动文件,需要下载导入到工程中。另外,需要注意引脚的接法和配置,尤其是P0和P1的配置需要根据实际使用情况进行修改。
