Custom Firmware Development for ESP32/ESP8266

Project Title:
Firmware Driver Development for Custom Hardware on ESP32/ESP8266 (Arduino/PlatformIO)

Project Description:
We have completed custom hardware development and require firmware driver development for our ESP32/ESP8266-based device. The driver must be production-ready, modular, and follow Arduino library standards.

Key Requirements (Short SRS):

Target MCU: ESP32 / ESP8266

Framework: Arduino (C++)

IDE: PlatformIO (Arduino framework) — must also compile in standard Arduino IDE

Communication Protocols: I2C and SPI (protocol selectable during initialization)

Driver Structure:

Arduino library format (.h / .cpp)

Class-based implementation

begin() initialization function

Configurable I2C address / SPI chip select (CS)

Example sketch included

Clean, modular, well-commented, production-ready code

Deliverables:

Full source code (.h / .cpp)

Example Arduino sketch demonstrating usage

Brief documentation / README

Timeline & Budget:
Please share your estimated timeline and fixed-cost quotation. We prefer developers with prior ESP32/Arduino library development experience.

Preferred Communication:
Kindly respond with your portfolio, relevant experience, and proposed timeline + cost.
