User Guide

Important: CAMCALC is NOT permitted for use during exams. This message is displayed every time the program starts. Using CAMCALC during an exam may result in disqualification or other academic penalties. CAMCALC is intended for studying, homework, and personal use only.

CAMCALC must be loaded onto your calculator before first use.

2.1 First-Time Transfer

Step 1: Turn on your calculator and make sure you are at the home screen (press [2nd] then [QUIT] if you are in a menu or editor).

Before using any online features (AI chat, math solver, games), you need to save your WiFi network credentials. This only needs to be done once. Your WiFi details are saved and remembered across restarts.

3.1 Starting the Configuration Portal

Step 1: From the main menu, select SETTINGS.

Step 2: From the Settings menu, select CONFIGURE.

Step 3: Wait while the configuration portal starts.

Your CAMCALC device is now broadcasting its own WiFi network that you will connect to from your phone or computer.

3.2 Connecting to the Portal from Your Phone

Step 1: On your phone (or computer), open your WiFi settings.

Step 2: Find and connect to the network called CAMCALC-CONFIG.

Step 3: When prompted for a password, enter: config123

Step 4: Once connected, open a web browser (Chrome, Safari, etc.).

Step 5: In the address bar, type: 192.168.4.1 and press Go.

Step 6: You will see a login page. Enter the credentials shown on your calculator screen.

Step 7: Press Sign In. You will be taken to the dashboard.

3.3 Saving Your WiFi Network

Step 1: From the dashboard, tap WiFi (or navigate to the WiFi page).

Step 2: The portal will scan for available WiFi networks. A list of nearby networks will appear.

Step 3: Tap on the network you want CAMCALC to use (e.g., your home WiFi or phone hotspot).

Step 4: Enter the WiFi password in the password field.

Step 5: Press Test Connection. The portal will test whether the password is correct.

Step 6: If the test is successful, you will see a confirmation message with an IP address.

Step 7: A Save button will appear. Press it to save your WiFi credentials.

Step 8: You will see a confirmation that the credentials are saved.

3.4 Closing the Portal

Step 1: Go back to your calculator and press [CLR] (the CLEAR key).

Step 2: The screen will briefly show "STOPPING..." and then return to the Settings menu.

Step 3: On your phone, disconnect from the CAMCALC-CONFIG network and reconnect to your regular WiFi.

After saving your WiFi credentials (Section 3), you need to connect to WiFi each time you turn on the calculator. This is a quick one-step process.

Step 1: From the main menu, select SETTINGS.

Step 2: Select CONNECT.

Step 3: The screen will show "CONNECTING..." while CAMCALC connects to your saved network.

Step 4: If successful, you will see a confirmation with the network name and device version.

Step 5: Press [ENTER] to return to the Settings menu.

Common Connection Errors

"Network not found" — Your saved WiFi network is not in range. Move closer to your router or hotspot.

"Wrong password" — The saved password is incorrect. Go to CONFIGURE to re-enter it.

"Connect timeout" — The network was found but the connection timed out. Try again.

The Settings menu provides access to connectivity, keepalive, configuration, and update options.

5.1 Ping (Keepalive)

If you are using a mobile phone hotspot, the hotspot may automatically disconnect after a period of inactivity. The Ping feature sends a small signal at regular intervals to keep the connection alive.

Step 1: From the Settings menu, select PING.

Step 2: You will see your current ping setting (e.g., "ON 45" or "OFF 0").

Step 3: Choose an interval from the menu. Select your preferred interval. A shorter interval uses slightly more battery but is more reliable at keeping the connection alive. 45 seconds is recommended for most mobile hotspots.

Step 4: You will see a confirmation message. Press [ENTER] to return to Settings.

5.2 Update

CAMCALC can update its own firmware over WiFi. This ensures you always have the latest features and fixes.

Step 1: Make sure you are connected to WiFi first (use CONNECT).

Step 2: From the Settings menu, select UPDATE.

Step 3: The screen will show your current firmware version and check for updates.

Step 4: If your firmware is up to date, you will see "UP TO DATE". Press [ENTER] to go back.

Step 5: If an update is available, you will see "UPDATE AVAILABLE" with two options: Press [ENTER] to install the update, or press [CLR] to cancel.

Step 6: If you choose to install, the update will begin downloading.

Text Chat lets you ask questions and get answers from an AI assistant, directly on your calculator. You can also have follow-up conversations.

6.1 Starting a Chat

Step 1: From the main menu, select ASK AI.

Step 2: You will see the GPT Mode menu.

Step 3: Select TEXT CHAT.

Step 4: If you are not connected to WiFi, you will see a message telling you to connect first.

6.2 Last Prompt (Resend)

When you enter Text Chat, CAMCALC checks if you have a previous prompt saved. This is useful if your last question failed due to a network error, or if you want to re-ask a previous question.

If a previous prompt exists: Press [ENTER] to resend the same question without retyping it, or press [CLR] to type a new question instead.

If no previous prompt exists, you will go directly to the question input.

6.3 Typing Your Question

Step 1: Type your question using the calculator keyboard. Press [ALPHA] to type letters, [2nd] then [ALPHA] to lock alpha mode for faster typing.

Step 2: Press [ENTER] when you are done typing.

Step 3: The screen will show "LOADING..." while your question is sent to the AI.

6.4 Reading the Response

The AI response will appear on the screen. Because the calculator screen is small, long responses are split into pages.

Navigation controls: Press [LEFT] arrow to go to the previous page. Press [RIGHT] arrow to go to the next page. Press [ENTER] to type a follow-up question. Press [CLR] to go back to the GPT Mode menu.

Each page displays approximately 100 characters. The page number is shown at the bottom (e.g., [1/3] means page 1 of 3).

6.5 Follow-Up Conversations

CAMCALC supports multi-turn conversations. The AI remembers what you discussed and can answer follow-up questions in context.

Step 1: While viewing an AI response, press [ENTER].

Step 2: Type your follow-up question and press [ENTER].

Step 3: The AI response will appear. You can ask things like "explain that more" or "give me an example" without repeating your original question.

You can continue asking follow-ups as many times as you like.

6.6 Error Handling and Retry

If something goes wrong (network timeout, server error, WiFi disconnection), you will see an error screen.

Press [ENTER] to retry the same message immediately without retyping. Press [CLR] to go back to the GPT Mode menu.

If you go back to the menu, your question is still saved. The next time you enter Text Chat, you will see the Last Prompt (Resend) option.

Math Solver uses AI to solve math problems and displays the solution as step-by-step images on your calculator’s graph screen.

7.1 Asking a Math Question

Step 1: From the main menu, select ASK AI.

Step 2: Select MATH SOLVER.

Step 3: If you are not connected to WiFi, you will see a message telling you to connect first.

Step 4: Type your math question. For example: integrate x^2, solve 2x+3=7, or derivative of sin(x).

Step 5: Press [ENTER]. The screen will show a loading message.

7.2 Viewing Solution Steps

Once the solution is ready, the first step will appear as a graphical image on the calculator’s graph screen. Each step shows a title, the mathematical expression, and a brief explanation.

Navigation controls: Press [RIGHT] arrow to go to the next step. Press [LEFT] arrow to go to the previous step. Press [CLR] to exit back to the GPT Mode menu.

Steps are numbered (e.g., 1/3, 2/3, 3/3) so you always know where you are in the solution.

7.3 Error Handling and Retry

If an error occurs while solving: Press [ENTER] to retry the same question, or press [CLR] to go back to the GPT Mode menu.
