Firmware Development
Firmware Development
Creates maintainable device firmware, drivers, control logic, diagnostics, bootloaders, and communications in embedded C and C++.
Quick Service Summary
- Parent Domain: Embedded Systems Design and Development Services
- Execution Model: Custom Engineering Scope
- Verification: Bench & Functional Testing
- Delivery Deliverables: Schematics, Code & Documentation
The Engineering Challenge
Unstructured firmware leads to system lockups, race conditions, memory corruption, and extreme difficulty in maintaining code across product revisions.
The Desired Outcome
Modular, MISRA-conscious embedded C/C++ firmware featuring layered hardware abstraction, deterministic task execution, non-blocking I/O, and secure update capabilities.
Core Technical Capabilities
Application-specific engineering focused on reliability, performance, and maintainability.
Bare-metal and RTOS-based firmware architectures (FreeRTOS, Zephyr)
Low-level peripheral driver development (I2C, SPI, UART, PWM, ADC, DMA)
Fail-safe bootloaders with dual-bank Flash and secure OTA/serial firmware update
Real-time control algorithms: PID loops, motor control, and sensor filtering
Fault-handling routines, watchdog management, and non-volatile crash dumps
Unit testing, static code analysis, and hardware-in-the-loop (HIL) verification
Technical Approach
Our firmware engineering adopts strict separation between the Hardware Abstraction Layer (HAL), board support packages (BSP), and application business logic. State machines ensure deterministic execution and predictable recovery.
Required Customer Inputs
Target microcontroller datasheet, hardware schematics, pin configuration, state transition diagrams or control logic requirements.
Project Deliverables
- Fully documented C/C++ source code repository with build scripts (CMake/Make)
- Compiled binary/hex files with memory map reports
- Bootloader integration instructions and serial/OTA flashing guidelines
- Software architecture specification and API reference documentation
Scope Boundaries & Safety Safeguards
Cryptographic keys and security certificates must be generated and secured by the customer. TC Smart Technology adheres to transparent engineering standards: solutions do not bypass machine safety interlocks, and all AI features retain human-in-the-loop governance.
