代号：Epsilon ε
在大抑郁时代过后的一次编程尝试。
本程序用于将 Arduino 与电脑上的 AIDA64 进行互动，监测电脑各硬件的温度、功率，以及内存/显存占用等。
- 一块 LCD 2004 液晶屏，有 I²C 背板
- 一块 Arduino Uno 主控板（或其它兼容型号），带 USB 通讯口
- AIDA64，灵感源自cokesu
- Visual Studio Code，以及插件 Platform IO
- 液晶屏驱动库：LiquidCrystal_I2C
- 通过 USB 线，把 Arduino 连接到 Windows 电脑。可能需要手动安装串口驱动。
- 于“设备管理器”的“COM 端口”处，找到其串口芯片名称（例如 CH340），记住其端口号（如
COM3）。 - 通过 Visual Studio Code 加载本仓库。记住，先准备好插件 Platform IO。
如通过 Arduino IDE 加载，应复制main.cpp内容并安装上述 LCD 驱动库。 - 本程序被设定以 9600 bps 作为串口默认波特率，存于
clBAUDRATE。在源程序中可依喜好改动之；可能还需于“设备管理器”同步调整串口的波特率（每秒位数）。 - 烧录本程序。
- 打开 AIDA64，进行设置：
- 在“硬件监视工具”的“LCD”一项，选中 Pertelian 选项卡；
- “LCD 端口”选中刚才记住的端口号（如
COM3）； - “LCD 类型”必须为
20x4； - 勾选“启用 Pertelian X2040 LCD 支持”。
- 再在左边进入“LCD 项目”，导入配置文件
lcd-items.pelcd。该配置所引入的项目如下。
| 项目 | 标签（Label） | 最大长度 | 量程 | X,Y坐标 |
|---|---|---|---|---|
| 温度 - CPU Package | T |
2 | -9 ~ 99 | 0, 0 |
| 温度 - GPU1 二极管 | t |
2 | -9 ~ 99 | 1, 1 |
| 系统 - CPU 使用率 | L |
3 | 0 ~ 100 | 6, 0 |
| 功耗 - CPU Package | P |
6 | 0 ~ 999.99 | 12, 0 |
| 功耗 - GPU1 | p |
6 | 0 ~ 999.99 | 11, 1 |
| 系统 - GPU1 核心频率 | f |
4 | 0 ~ 9999 | 5, 2 |
| 系统 - 已用内存 | M |
6 | 0 ~ 999999 | 12, 2 |
| 系统 - GPU1 专用内存使用 | m |
5 | 0 ~ 99999 | 1, 3 |
| 温度 - 主板 MOS | B |
2 | -9 ~ 99 | 6, 1 |
| 温度 - 固态硬盘 | b |
2 | -9 ~ 99 | 0, 2 |
注意：
- 不要勾选“显示单位”（Show unit）！
- 串口默认波特率为 9600 bps，确保开箱即用；推荐以 115200 bps 工作，以获得最佳体验。可于源代码和“设备管理器”自行调整波特率。
- 每个项目之间应当至少留出一个空格。
- 如某一行的第 20 个字符被使用，则下一行第 1 个字符必须为空格。下例可见
t 56前面有一个空格（因上一行P 123.14使用了第 20 个字符空间）。
- 如某一行的第 20 个字符被使用，则下一行第 1 个字符必须为空格。下例可见
- 温度分类中的“固态硬盘”名称因其型号而异，图标均为“硬盘”。
可于“LCD 项目”上方的模拟显示器中预览：
T 85 f 1920 P 123.14
t 56 b 54 p 100.86
B 69 L 100 M 113939
m 11785
保存设置，将可在 LCD 2004 屏幕上见到：
G:56℃ 100.86W 1920√
C:85℃ 123.14W 100%
Mem:113939 MOS:69℃
VRAM:11785 SSD:54℃
- 温度值范围有限，如高于 99 度或低于零下 9 度，显示将出现异常（如 100 度显示为“10 ℃”）。
- 但是，由于固件会提前介入控温，诸组件温度原则上不会超过 100 度。有少数例外可能会超过该范围，例如：手动超频；笔记本上较激进的高温阈值（或“温度墙”，Tj）设置；-10 ℃以下环境中开机等。
- 将来可能考虑加入过热、低温检测和指示。
- 类似地，本程序不适用于 RAM 容量 ≥ 1000 GB，或安装两颗或以上处理器、GPU 或 SSD 的平台。如有相关需求，请自行修改源代码以适配。
- 在较高波特率下（如 115200 bps），初期可能出现少许显示错误。例如，初次接收数据时有 1~2 个项目空缺，但此后恢复正常。
Codename: EPSILON ε
Just an attempt after my Great Depression.
The program was designed for hardware monitoring by setting up an Arduino to interact with AIDA64.
- An HD44780-powered LCD screen with 4 rows, 20 columns (marketed as "LCD 2004" or "LCD 20x4"), with an I²C backpack
- An Arduino Uno (or its equivalents), with a USB port
- AIDA64, inspired by cokesu
- Visual Studio Code with the addon Platform IO installed
- Library LiquidCrystal_I2C
- Connect an Arduino to a Windows PC with a USB cable. Manual installation of Serial driver may be required.
- Check out the Serial port used by Arduino in, for example, Device Manager on Windows. It should look like
COM3. - Load this repo in Visual Studio Code with the addon Platform IO. Use with Arduino IDE is also feasible; just copy
main.cppand install the LCD library. - The Serial was configured to work at 9600 bps, stored in
clBAUDRATE. You may reconfigure it, as well as that in Device Manager if needed. - Burn this program.
- In preferences of AIDA64, reach out to the "LCD" section under "Hardware Monitoring".
- Select
Pertelian, and configure "LCD port" to the serial port found above. For "LCD type",20x4should be chosen. - Turn on "Enable Pertelian X2040 LCD support".
- Enter the section "LCD Items" on the left, then import the profile
lcd-items.pelcd. Items to be shown follow.
| Item | Label | Max. Length | Limit | X,Y |
|---|---|---|---|---|
| Temperatures - CPU Package | T |
2 | -9 ~ 99 | 0,0 |
| Temperatures - GPU1 Diode | t |
2 | -9 ~ 99 | 1,1 |
| System - CPU Usage | L |
3 | 0 ~ 100 | 6,0 |
| Power Values - CPU | P |
5 | 0 ~ 999.99 | 12,0 |
| Power Values - GPU1 | p |
6 | 0 ~ 999.99 | 11,1 |
| System - GPU1 Clock | f |
4 | 0 ~ 9999 | 5,2 |
| System - Used Memory | M |
6 | 0 ~ 999999 | 12,2 |
| GPU1 Used Dedicated Memory | m |
5 | 0 ~ 99999 | 1,3 |
| Temp. - Motherboard MOS | B |
2 | -9 ~ 99 | 6,1 |
| Temperatures - SSD | b |
2 | -9 ~ 99 | 0,2 |
The emulated screen on the top of "Preferences" should look like this:
T 85 f 1920 P 123.14
t 56 b 54 p 100.86
B 69 L 100 M 113939
m 11785
Notes:
- The recommended baudrate for best experience is 115200 bps. However, the default baudrate has been set to 9600 bps in favor of plug-and-play. You may reconfigure the baudrate both in source code and in Device Manager.
- At least one space SHOULD be reserved between each items.
- In cases when the last charactor on any line has to be utilized, a space MUST be reserved as the first character on the next line. This can be seen ahead of "GPU1 Temp. (
t 56)" .
- In cases when the last charactor on any line has to be utilized, a space MUST be reserved as the first character on the next line. This can be seen ahead of "GPU1 Temp. (
Then, on the LCD 2004 screen, they will look like this:
G:56℃ 100.86W 1920√
C:85℃ 123.14W 100%
Mem:113939 MOS:69℃
VRAM:11785 SSD:54℃
- Showing of temperatures ≥ 100° or ≤ -10° Celsius will misbehave, for example, "10 ℃" will be displayed with actual temperature of 100°.
- However, due to thermal regulation conducted by firmwares, temperatures should be expected to stay within the limits. These limits may be exceeded in few scenarios, including: manual overclocking; aggressive configurations of Junction Temperature (Tj) on select laptops; and starting up with room temperature below -10° Celsius.
- Detection for overheating or subcooling may be planned in future.
- The program is not applicable on systems with RAM ≥ 1000 GB, or with 2 or more processors/GPUs/SSDs. You may customize the displays to monitor them.
- At a significantly higher baudrate (e.g. 115200 bps), negligible errors may be spotted. In my testing, 1~2 items were missing on the first time of reading, but were not thereafter.
