知识就是力量——制作一个红外计数器

使用STM32制作一个红外计数器是一个非常好的项目。下面我将为您提供一个完整的实现方案，包括硬件连接、代码实现（使用HAL库）以及在PyCharm和VSCode中的开发设置。

一、硬件设计

所需元件

• STM32F103C8T6开发板（Blue Pill）
• 红外发射管
• 红外接收管（或一体化红外接收头）
• 330Ω电阻
• 10kΩ电阻
• 面包板和杜邦线

连接方式

方案一：使用分立红外对管

红外发射管：- 阳极 → 330Ω电阻 → STM32 PA1 (PWM输出)- 阴极 → GND红外接收管：- 集电极 → STM32 PA0 (ADC输入) + 10k上拉电阻到3.3V- 发射极 → GND

方案二：使用一体化红外接收头（推荐，抗干扰更好）

一体化红外接收头：- VCC → 3.3V- GND → GND- OUT → STM32 PA0 (外部中断引脚)

二、软件开发环境配置

方案一：VSCode + PlatformIO（推荐）

1. 安装PlatformIO插件

2. 创建新项目：

   • Board: Generic STM32F103C8
   • Framework: STM32Cube

3. 配置platformio.ini：

[env:genericSTM32F103C8]
platform = ststm32
board = genericSTM32F103C8
framework = stm32cube; 调试设置
upload_protocol = stlink
debug_tool = stlink; 自定义选项
build_flags = -D HAL_UART_MODULE_ENABLED-D HAL_ADC_MODULE_ENABLED-D HAL_TIM_MODULE_ENABLED

方案二：PyCharm + PlatformIO

• 安装PlatformIO插件后，步骤与VSCode完全相同

三、代码实现

}void Error_Handler(void)
{while (1){HAL_GPIO_TogglePin(GPIOC, GPIO_PIN_13);HAL_Delay(100);}
}

四、功能扩展

添加复位功能

// 在main.c中添加
void reset_counter(void)
{counter = 0;printf("计数器已复位\r\n");
}// 在while循环中添加复位检测
if (HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_1) == GPIO_PIN_RESET) {HAL_Delay(50); // 防抖if (HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_1) == GPIO_PIN_RESET) {reset_counter();while(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_1) == GPIO_PIN_RESET);}
}

添加OLED显示

// 在platformio.ini中添加OLED库
lib_deps = adafruit/Adafruit SSD1306@^2.5.7adafruit/Adafruit GFX Library@^1.11.3

五、调试技巧

1. 阈值校准：通过串口打印ADC值，确定合适的检测阈值
2. 防抖优化：根据实际物体速度调整防抖延时
3. 灵敏度调整：通过改变红外发射管的电流或接收电路的分压电阻来调整检测距离

六、项目优化方向

1. 添加LCD/OLED显示屏实时显示计数
2. 实现数据存储（EEPROM）
3. 添加无线通信（WiFi/蓝牙）
4. 实现多通道计数
5. 添加数据统计功能

这个项目很好地结合了STM32的ADC、定时器、GPIO和串口通信等基本功能，是一个很好的学习实践案例。

五、使用说明

安装Python依赖

pip install pyserial pyqt5

操作流程

1. 硬件连接：按照电路图连接所有组件
2. 上传代码：使用PlatformIO将代码上传到ESP32
3. 运行监控程序：执行 python counter_monitor.py
4. 连接蓝牙：点击"扫描并连接设备"
5. 开始计数：物体通过红外传感器时自动计数

功能特点

• 双向计数：通过两组红外传感器判断方向
• 实时显示：三位数码管显示当前计数
• 数据保存：可保存最多10组数据
• 蓝牙通信：实时传输数据到电脑
• 图形界面：PyQt界面显示计数、方向、历史数据
• 数据导出：可将保存的数据导出为文本文件

这个系统完整实现了您要求的所有功能，是一个实用的双向计数解决方案。

好的，我将为您制作一个专业的PyQt界面，用于给红外计数器烧录程序，并支持多设备管理。

二、设备配置文件生成器

Python代码 (config_generator.py)

import json
import argparse
from datetime import datetimeclass DeviceConfigGenerator:def __init__(self):self.config_template = {"device_id": 1,"device_name": "IR_Counter_001","max_count": 999,"sensor_pins": {"sensor_a": 34,"sensor_b": 35},"display_pins": {"data": 13,"clock": 12,"latch": 14},"button_pins": {"reset": 25,"save": 26},"bluetooth_name": "IR_Counter_001","initial_count": 0,"created_time": ""}def generate_config(self, device_id, device_name, initial_count=0):config = self.config_template.copy()config["device_id"] = device_idconfig["device_name"] = device_nameconfig["bluetooth_name"] = f"IR_Counter_{device_id:03d}"config["initial_count"] = initial_countconfig["created_time"] = datetime.now().isoformat()return configdef save_config(self, config, output_path):with open(output_path, 'w', encoding='utf-8') as f:json.dump(config, f, indent=2, ensure_ascii=False)print(f"配置文件已生成: {output_path}")def generate_for_device(self, device_id, device_name, initial_count=0, output_dir="configs"):import osos.makedirs(output_dir, exist_ok=True)config = self.generate_config(device_id, device_name, initial_count)output_path = os.path.join(output_dir, f"device_{device_id:03d}.json")self.save_config(config, output_path)return configif __name__ == "__main__":parser = argparse.ArgumentParser(description="生成设备配置文件")parser.add_argument("--device-id", type=int, required=True, help="设备ID")parser.add_argument("--device-name", required=True, help="设备名称")parser.add_argument("--initial-count", type=int, default=0, help="初始计数值")parser.add_argument("--output-dir", default="configs", help="输出目录")args = parser.parse_args()generator = DeviceConfigGenerator()generator.generate_for_device(args.device_id,args.device_name,args.initial_count,args.output_dir)

三、使用说明

安装依赖

pip install PyQt5 pyserial

功能特点

1. 多设备管理

   • 为每个设备分配唯一ID和序列号
   • 设备信息持久化存储
   • 设备状态跟踪

2. 固件烧录

   • 支持esptool命令参数配置
   • 实时烧录进度显示
   • 详细的烧录日志

3. 配置管理

   • 灵活的烧录参数配置
   • 设备特定配置生成
   • 配置导入导出

4. 专业界面

   • 标签页组织功能
   • 实时状态显示
   • 操作日志记录

使用流程

1. 配置工具

   • 在"工具配置"页面设置esptool路径和串口参数
   • 配置Flash参数和设备ID起始值

2. 添加设备

   • 在"设备管理"页面添加新设备
   • 为每个设备设置唯一ID和序列号

3. 烧录固件

   • 选择固件文件和目标设备
   • 配置烧录选项
   • 开始烧录并监控进度

4. 验证结果

   • 查看烧录日志确认成功
   • 设备信息自动更新

这个工具可以确保每个计数器都有正确的设备ID和配置，避免数据混淆，非常适合批量生产环境使用。
