功能要求
功能概述
- 使用 STM32 微控制器 ADC 通道（PB0）测量竞赛板电位器 R37 输出的模拟电压信号 VR37。
- 使用 PA6 输出频率固定为 100Hz，占空比可调节的脉冲信号。
- 使用 PA7 输出频率固定为 200Hz，占空比可调节的脉冲信号。
- 完成 B1、 B2、 B3、 B4 四个独立按键的动作扫描。
- 按照显示要求，通过 LCD 显示数据和参数
性能要求
- 数据显示界面下电压值更新时间：≤0.1 秒；
- PA6、 PA7 输出信号占空比跟随响应时间：≤1 秒；
- 按键响应时间：≤0.1 秒；
- 输出信号频率精度要求：≤±5%；
- 输出信号占空比精度要求：≤±5%。
运行模式
-
自动模式： PA6 和 PA7 输出信号占空比相同，与 VR37的关系如下：
‘ VR37 = 3.3 * D ’ - 当 VR37 = 0V 时， PA6 和 PA7 持续输出低电平。
- 当 VR37 = 3.3V 时， PA6 和 PA7 持续输出高电平。
-
手动模式： PA6、 PA7 输出信号占空比通过按键控制，与 VR37值无关。
LCD 显示界面
- 数据显示界面
在数据显示界面下，通过 LCD 显示采集电压值和当前运行模式，电压数据保留小数点后两位有效数字。
- 参数显示界面
在参数显示界面下，通过 LCD 显示 PA6 通道和 PA7 通道输出占空比参数。
注意：
占空比参数仅在手动模式下起作用，在自动模式下，输出信号占空比取决于电位器电压值 VR37。
- LCD 通用显示要求
- 显示背景色(BackColor)：黑色
- 显示前景色(TextColor)：白色
- 请严格按照图示 2、 3 要求设计各个信息项的名称（区分字母大小写）
和行列位置。
按键功能
- B1:定义为“界面切换”按键，切换 LCD 显示“数据界面”和参数界面。
- B2:每次按下 B2 按键， PA6 手动模式占空比参数加 10%，占空比可调整范围10% - 90%，占空比参数增加到90%后，再次按下 B2 按键，返回 10%。
- B3:每次按下 B3 按键， PA7 手动模式占空比参数加 10%，占空比可调整范围10% - 90%， 占空比参数增加到 90%后，再次按下 B3 按键，返回 10%。
- B4:定义为“模式控制”按键，切换“手动模式”和自动模式。
- 通用按键设计要求
- 按键应进行有效的防抖处理，避免出现一次按下、多次触发等情形。
- 按键 B2、 B3 仅在参数显示界面有效。
LED 指示灯功能
- 自动模式 LD1 点亮， 手动模式 LD1 熄灭。
- 数据界面 LD2 点亮，参数界面 LD2 熄灭。
初识状态说明
- 上电默认处于“自动模式”。
- 上电默认处于数据显示界面。
- 上电默认参数,PA6 通道占空比 10%， PA7 通道占空比 10%。
实现
因为是竞赛类比赛，非做项目，为了方便，把所有代码放在main.c中了。
