Flashing and Setting Up Makcu - How to Connect Without Errors

Flashing Makcu

A step-by-step guide for stable, error-free operation of the device

🔧 Preparing for Flashing

• 🖥️ Run from a second computer

To avoid temporary files on your main PC, run the AIO Tool from a second computer.

While running, the program unpacks files into a temporary folder.

• 📦 Download AIO Tool

Download the tool from GitHub:

https://github.com/terrafirma2021/MAKCM_v2_files

• ⚙️ Launch AIO Tool

Open the program and wait for the automatic update to finish.

• 🔌 Prepare a USB cable

You will need a single USB cable for flashing. Connect it to the computer from which the flashing will be performed.

🧩 Device Flashing Stages

📤 1. Remove the Top Cover

Take the Makcu out of the getdma box. If it does not come with a box, ignore this step.

⬅️ 2. Flashing the Left Side

• Hold down the LEFT button.

• Connect the USB cable to the left USB port.
• Make sure the message "MCU connected in flash mode" appears in AIO Tool.

• Click Flash Left and wait for the flashing to finish.
• Disconnect the cable from the device.

➡️ 3. Flashing the Right Side

• Hold down the RIGHT button.

• Connect the cable to the right USB port.
• Click Flash Right in AIO Tool.

• Wait for the flashing to finish.

🧰 Installing the Driver and Configuring the COM Port

📥 1. Install the CH343SER.INF Driver

Download the driver from GitHub:

https://github.com/terrafirma2021/MAKCM_v2_files

Extract the archive to a convenient folder, then right-click the .CH343SER.INF file and select Install.

⚙️ 2. Configuring the COM Port (on the second PC)

Open Device Manager and expand the Ports (COM & LPT) section.

Right-click the COM device → Properties → the Port Settings tab → the Advanced button.

Set the COM port number to a value below 10 and click OK.

🔄 3. Restart MAKCU to Apply the Changes

If AIO Tool is already open, close it. Then unplug and reconnect the left cable of the MAKCU.

Connecting Makcu

Step-by-step instructions

🔌 Connecting After Flashing

• The left cable (Main PC) connects to your main computer.
• The middle cable connects to the second PC used for flashing.
• The right cable connects to the MAKCU mouse.

🧪 Testing After Flashing

After flashing, MAKCU is not tested with the "TEST" button. Instead, use the command:

km.move(100,100)

This command can be sent through the Makcu terminal.

📡 Changing the Baud Rate

To change the MAKCU baud rate, press the left button 4 times within 2 seconds. The LED will indicate the current speed:

• 💡 4 blinks — 4 Mbit/s (4000000)
• 💡 1 blink — 115200 bit/s

Pressing again toggles the mode. The selected setting is saved automatically.

⚠️ Settings in Windows Device Manager do not affect the actual speed — MAKCU uses its own configuration.
