1.2.0

Included In This Release

Ready-to-flash firmware for Waveshare ESP32-C6-LCD-1.47.

Firmware:

• works with the KY-018 light sensor
• shows the current reading on the LCD
• shows the sensor status on screen
• sends telemetry over USB Serial
• stays compatible with the Windows application from this repository

Release Files

• luma-bloom-pc-app_0.3.0_win-x64-portable.zip - folder with the exe file
• luma_bloom_esp32c6_0.3.0_merged.bin - firmware binary for flashing the device

What Changed

• Added ESP32-C6 startup calibration driven by pc-app, with calibrate command handling and calibration result responses.
• Changed ESP32-C6 telemetry so value is now a calibrated normalized reading in the 0..1000 range, with additional raw and calibrated fields.
• Updated the Windows application to detect the ESP32-C6 normalized profile, collect startup samples, send calibration data, and use the calibrated values for brightness control.
• Reworked the ESP32-C6 LCD layer around generated screen layout files and runtime placeholders {{NORMALIZED}}, {{RAW}}, and {{STATUS}}.
• Refreshed the docs and release workflow to match the new calibration, telemetry, and packaging flow.

Supported Hardware

• Waveshare ESP32-C6-LCD-1.47 board
• KY-018 sensor

Wiring:

• VCC -> 3V3
• GND -> GND
• AO -> GPIO4

GPIO0 is no longer recommended for KY-018 on ESP32-C6 because it can interfere with normal board startup.
