CC2530是一款TI公司推出的低功耗无线SoC芯片,其主要应用于物联网等领域。如果您要进行CC2530的点播实验,应该是指使用CC2530进行无线通信的相关实验。
具体的CC2530点播实验代码可能因实验目的和具体实验环境而异,以下是一个简单的CC2530点播实验代码示例(基于Contiki OS):
```c
#include "contiki.h"
#include "dev/leds.h"
#include "net/rime/rime.h"
#include "dev/button-sensor.h"
/*---------------------------------------------------------------------------*/
PROCESS(example_broadcast_process, "Broadcast process");
AUTOSTART_PROCESSES(&example_broadcast_process);
/*---------------------------------------------------------------------------*/
static void
broadcast_recv(struct broadcast_conn *c, const linkaddr_t *from)
{
leds_toggle(LEDS_ALL);
printf("Received broadcast from %d.%d\n",
from->u8[0], from->u8[1]);
}
static const struct broadcast_callbacks broadcast_call = {broadcast_recv};
static struct broadcast_conn broadcast;
PROCESS_THREAD(example_broadcast_process, ev, data)
{
static struct etimer et;
PROCESS_EXITHANDLER(broadcast_close(&broadcast);)
PROCESS_BEGIN();
broadcast_open(&broadcast, 129, &broadcast_call);
while(1) {
/* Delay 2-4 seconds */
etimer_set(&et, CLOCK_SECOND * 4 + random_rand() % (CLOCK_SECOND * 4));
PROCESS_WAIT_EVENT_UNTIL(etimer_expired(&et));
packetbuf_copyfrom("Hello", 6);
broadcast_send(&broadcast);
printf("Broadcast message sent\n");
}
PROCESS_END();
}
```
该示例代码使用了Contiki OS中的广播通信模块,当接收到其他节点的广播消息时,会让LED灯闪烁,并打印出广播来源节点的地址。在主循环中,每隔2-4秒钟,节点会发送一次"Hello"字符串的广播消息。您可以根据实验要求进行相应的修改和调整。
