为安信可小安派开发板写一段代码:雷达模组RD-03输出信号给小安派S1,检测到有人移动时,小安派语音播报“您已进入监控区域,请注意自己的言行举止”
猜猜看,以下代码都是哪些平台写出来的?是否可行,具有参考价值?
A.
- #include <stdio.h>
- #include <stdlib.h>
- #include <stdbool.h>
- #include <string.h>
- #include "freertos/FreeRTOS.h"
- #include "freertos/task.h"
- #include "driver/gpio.h"
- #include "driver/i2c.h"
- #include "sensor_api.h"
- #define GPIO_RADAR 2
- #define GPIO_SPEAKER 15
- bool has_detected = false;
- void app_main()
- {
- // 初始化 GPIO
- gpio_pad_select_gpio(GPIO_RADAR);
- gpio_set_direction(GPIO_RADAR, GPIO_MODE_INPUT);
-
- gpio_pad_select_gpio(GPIO_SPEAKER);
- gpio_set_direction(GPIO_SPEAKER, GPIO_MODE_OUTPUT);
-
- // 初始化 I2C 驱动和雷达模组

- i2c_init(&i2c_conf);
-
- // 启动雷达模组
- uint8_t addr = 0x10; // RD-03 的 I2C 地址为 0x10
- uint8_t reg = 0x00; // 读取状态寄存器
- uint8_t data = 0x00; // 先读取状态寄存器的值,确保初始状态为 0x00
- i2c_master_select(addr, true);
- i2c_master_write(&addr, ®, sizeof(reg));
- i2c_master_read(&addr, &data, sizeof(data));
- i2c_master_select(addr, false);
-
- // 启动 FreeRTOS
- vTaskStartScheduler();
- }
- void IRAM_ATTR check_radar()
- {
- // 检查雷达信号是否变化,如果变化则表示检测到人移动
- if (gpio_get_level(GPIO_RADAR) == 1) { // 如果雷达信号为高电平,表示检测到人移动
- if (!has_detected) { // 如果之前没有检测到人移动,则进行语音播报
- has_detected = true; // 标记已经检测到人移动
- // 控制扬声器播放语音“您已进入监控区域,请注意自己的言行举止”
- // 此处需要使用小安派开发板提供的语音播报 API 进行实现,具体实现方式根据开发板的文档进行编写,这里不再赘述。
- }
- } else { // 如果雷达信号为低电平,表示没有检测到人移动
- if (has_detected) { // 如果之前检测到人移动,则重置标记并处理相应的逻辑(例如重置扬声器)
- has_detected = false; // 重置标记
- // 控制扬声器停止播放语音(具体实现方式根据开发板的文档进行编写,这里不再赘述)
- }
- }
- }
