About this Gig
Headline: Expert ESP32 Embedded Firmware: Real-Time TFT/OLED UI and Robust IoT Connectivity!
I specialize in delivering clean, scalable, and high-performance Embedded C++ firmware on the ESP32 platform for professional IoT projects. My service covers the entire embedded stack, from sensor integration to dynamic display UI and advanced communication protocols.
My Expertise Covers:
- Real-Time Display UI: Custom, aesthetically superior display dashboards on TFT or OLED screens. I handle graphics, custom fonts, and dynamic data presentation for sensors like Temperature and Humidity.
- Advanced Connectivity: Development of robust Bluetooth Low Energy (BLE) firmware, supporting both Client (Scanning/Connecting) and Server (Advertising/Notifying) roles for seamless bidirectional IoT communication.
- Firmware Quality: Optimized code using FreeRTOS for multitasking, ensuring high reliability and efficiency, including low-power consumption modes.
- Sensor Integration: Expertise in integrating standard and custom sensors using I2C, SPI, and custom drivers.

FAQ
Which display libraries do you use?
I use highly optimized libraries like TFT_eSPI and Adafruit GFX (including Adafruit_SSD1351 from your project) for fast TFT/OLED rendering and efficient memory use.
Do you provide the full source code?
Yes, all packages include the complete, documented Embedded C++ firmware and necessary files (like .ino and SPIFFS images).
Does this include mobile app development for BLE?
No, this Gig is for the ESP32 firmware only. I can, however, provide consultation to your mobile developer on the correct GATT Service integration.
What if I need a sensor not listed (e.g., Pressure or Gyroscope)?
I have experience with a wide range of custom sensor integration. Please message me before ordering for a custom quote!
