Install & use
Let AI help you install
Connect the device and give AI the detection results together with this firmware information.
1
Confirm the device and connect USB
USB chip information cannot distinguish monochrome from four-color screens. Confirm the model first.
Connect USB and detect the device
Read the chip and capacity first, so AI needs fewer follow-up questions.
Detection may restart the device into download mode. It does not flash firmware; you still need to confirm the display model.
Not detected yet. You can also copy the task first and ask AI to help connect.
2
Give the installation task to AI
Codex on your computer can install dependencies and run programs locally.
What AI will do next
Check compatibility → Prepare firmware and a full backup → Assist with local installation → Verify first run
After copying, start a new chat in Codex on your computer and paste the task.
See the task for AI
Only project information and the device details selected here are included. Network addresses, accounts and keys are configured locally during installation.

After installation, check this
The device shows the expected Paperwake screen and continues to work after repeated updates.
Ask AI to report the installation location, verification results and how to start again. Continue in the same conversation if something goes wrong.

Prepare your local editor
Run Control Tower on your computer. The web editor listens on localhost by default and needs no Paperwake cloud account. Your computer and device must communicate over the home LAN.
Preview first, then connect hardware
You can try layouts and pushing with the repository's simulated device first. Simulation does not prove output on a real panel or hardware compatibility.
Prepare the device firmware
Prepare ESP-IDF 6.x using the firmware instructions. Confirm the NOTE4C four-color configuration and back up the complete Flash, then build and install. This site does not provide a ready-to-install universal image.
Pair and send an image
Pair a real NOTE4C using Control Tower's device flow. Content queues while the device sleeps and is delivered during its wake window. Check states such as confirmed display to determine the result.
Project documentation checked · Installation and LAN delivery await physical-device validation. Generating a task does not send it or run an installation automatically.
Frequently asked questions
Will the calendar work on its own after flashing?
You still need Control Tower running on your computer to configure sources and deliver images. The device and editor together form the complete workflow.
Why doesn't a push appear immediately?
Wi-Fi is off during deep sleep. The editor can deliver content during the network window after a scheduled wake or button press.
