DIY Your System
Build and flash the official Read Pico demo with ESP-IDF, then use its board support and drivers for your own system.
Build your Read Pico system from the official demo repository, modify its demo pages, or reuse its board support and chip drivers.

Requirements
Install and activate ESP-IDF v6.1, and prepare Git and a USB data cable. The target is ESP32-S3. The repository's Flash driver depends on an interface introduced in ESP-IDF v6.
Build and flash
git clone https://github.com/MindReset/read_pico_firmware.git
cd read_pico_firmware
idf.py set-target esp32s3
idf.py build
idf.py -p PORT flash monitorReplace PORT with the actual serial port, such as /dev/cu.usbmodem… on macOS, /dev/ttyACM0 on Linux, or COM3 on Windows. Flashing replaces the current system. Press Ctrl+] to exit the serial monitor.
After flashing, use Demo System to check hardware and interactions.
Board configuration
The 120 MHz Flash / PSRAM timing in sdkconfig.defaults depends on the actual Flash part on the board. The repository's sdkconfig.ci uses default timing for compilation checks only; it does not establish on-device validation. Do not apply this board configuration directly to other hardware.
Panel VCOM is paired with the panel at the factory and stored in the PMU. The system reads it at boot; it is not stored locally or user-editable.
Source entry points
| Path | Purpose |
|---|---|
main/apps/ | Individual demo pages |
main/app/app_registry.c | Function menu registration and order |
main/app/app.h | The app_desc_t page interface |
components/read_pico/ | Board support for I2C, display, TF card, buzzer, and more |
components/read_pico_pmu/ | Host side of the CW32L010 power management protocol |
components/ | Touch, accelerometer, IO expander, display power, and other drivers |
tools/ | Font and image conversion scripts |
To add a demo, implement the required app_desc_t callbacks in main/apps/, then add the page to the menu registry. See the repository README for pin assignments and component details.
USB not detected after wake
Follow the repository's troubleshooting sequence:
- Retry with a USB Type-A data cable.
- Run another sleep/wake cycle and retry.
- Restart the board and retry.
Licensing
The system itself uses Apache-2.0. Third-party components retain their own licenses, including LGPL-3.0-or-later for epdiy and SIL OFL-1.1 for the built-in font. Check the repository license notes and component LICENSE files before reuse or distribution.
