Descripción de la oferta
Hi, this Dual-ESP32 pen project is very interesting. I have experience with: - ESP32-C3 + PAA5100JE optical flow sensor - BNO08X 9-DoF IMU + Madgwick filter for sensor fusion - ESP32-2432S028R LVGL/TFT_eSPI UI development - MicroSD, Li-Po battery monitoring, OTA updates - UART protocol design with checksum My plan: 1. C3: Read sensors at 100Hz, fuse data, send 50Hz packets to LCD 2. LCD: Touch UI, live pose graph, battery %, DXF browser 3. Deliver: Clean PlatformIO code + README + Protocol PDF I can deliver in 3 weeks. Please check my portfolio. Let's discuss the sensor calibration. Thanks, Harsha What I need from you is production-ready, well-documented firmware on both sides, written in clean, non-blocking style so I can extend it later. Deliverables • ESP32-C3 firmware: drivers for PAA5100JE & BNO08X, lightweight fusion (Madgwick or similar), UART packetiser with checksum • ESP32-2432S028R firmware: touchscreen UI, graphic rendering of incoming pose data, battery status calculation, MicroSD DXF file manager, OTA/USB update handling • A simple, versioned UART protocol spec implemented on both boards and supplied as a brief PDF/README • Build and flash instructions for PlatformIO or ESP-IDF, plus commented source Acceptance will be based on stable 50 Hz data updates on the LCD, accurate battery read-out within ±3 %, smooth menu navigation on touch, and error-free flashing through USB-C on both MCUs.
