Software That Understands the Hardware
We build embedded software with a focus on long-term support: clear interfaces, traceable requirements, and pragmatic test hooks that reduce time spent debugging late in the cycle.
Our approach treats embedded software not as an afterthought to hardware design, but as a co-equal design activity that begins during schematic definition and continues through board bring-up and system validation. This hardware-software co-design methodology eliminates the costly surprises that arise when firmware engineers first encounter the hardware weeks after layout is complete.
ARM Cortex-M Platform Expertise
Our primary focus is the ARM Cortex-M family, which dominates modern microcontroller design across the STM32, NXP LPC/Kinetis, Nordic nRF, TI MSP432, and Microchip SAM series. We develop firmware using vendor HALs (STM32Cube, NXP MCUXpresso SDK, Nordic nRF Connect SDK) as well as direct register-level programming when HAL overhead is unacceptable for performance-critical paths.
For projects requiring deterministic real-time behavior, we integrate and configure real-time operating systems including FreeRTOS and Zephyr RTOS. Our RTOS integration goes beyond basic task creation — we design task architectures with proper priority assignment, implement inter-task communication using queues, semaphores, and event groups, and analyze worst-case execution times to guarantee deadline compliance.
Communication Stack Development
Modern embedded systems rarely operate in isolation. We develop and integrate communication stacks across the full range of embedded interfaces:
- SPI — High-speed peripheral communication with DMA transfers, configurable clock polarity/phase, and multi-slave bus management. Applications include ADC/DAC interfaces, external flash memory, and display controllers.
- I2C — Multi-device bus communication with address management, clock stretching support, and error recovery. Used for sensor arrays, EEPROMs, GPIO expanders, and power management ICs.
- UART / USART — Asynchronous serial communication with DMA-driven ring buffers, RS-485 half-duplex control, and protocol framing for Modbus RTU, NMEA, and custom binary protocols.
- CAN / CAN FD — Automotive and industrial bus communication with message filtering, priority-based arbitration, and application-layer protocol implementation (CANopen, J1939).
- Ethernet — TCP/IP networking using lightweight stacks (lwIP) with DHCP, DNS, MQTT, HTTP server/client, and Modbus TCP support.
Hardware-Software Co-Design
Our co-design process means that firmware requirements inform hardware decisions from the earliest stages:
- Peripheral pin assignments are optimized for DMA channel availability and interrupt priority grouping
- Clock tree configuration is planned during schematic review to ensure that peripheral bus speeds, PLL settings, and low-power clock sources meet firmware timing requirements
- Power domain partitioning is designed to support firmware-controlled sleep modes and selective peripheral shutdown
- Debug and programming interfaces (SWD, JTAG, UART bootloader) are accessible and properly routed for development and field diagnostics
- Test points are placed at firmware-critical signals to support bring-up and troubleshooting
