STM32 Development Services
InnovChip is a specialized STM32 firmware development company. We deliver production-grade embedded firmware for the entire STM32 portfolio — from ultra-low-power STM32L4 to high-performance STM32H7 series. Custom drivers, RTOS integration, bootloader, OTA updates, and secure firmware — we do it all.

Firmware Development Services
- Bare-Metal Firmware — Register-level programming for maximum performance and minimal footprint. Ideal for resource-constrained or real-time applications.
- HAL/LL Driver Development — Custom peripheral drivers using STM32Cube HAL or LL libraries. UART, SPI, I2C, CAN, USB, Ethernet, ADC, DAC, PWM, timer capture/compare.
- RTOS Integration — FreeRTOS, Zephyr, ThreadX porting and configuration. Task scheduling, inter-task communication, resource management, and power management.
- Bootloader Design — Custom bootloader with UART/USB/CAN/Ethernet firmware update. Dual-bank flash for fail-safe update with rollback protection.
- OTA Firmware Update — Over-the-air update system with AWS IoT Jobs, Azure Device Update, or custom MQTT-based solution. Delta update support to minimize data transfer.
- Secure Boot & Firmware — Secure boot implementation with hardware crypto (AES-256, ECC, SHA-256). Secure JTAG disable, read-out protection (RDP), and secure firmware verification.
- Low-Power Optimization — Sleep/Stop/Standby modes, peripheral clock gating, dynamic voltage scaling. Achieving sub-µA standby current for battery-powered devices.
Communication Protocol Stacks
We implement complete protocol stacks tested in industrial environments:
- CAN / CAN FD — J1939, CANopen, ISO-TP, UDS (ISO 14229) diagnostic stack
- Modbus RTU/TCP — Master and slave implementation, function codes 01-16
- MQTT — TLS-secured MQTT 3.1.1/5.0 client with QoS 0/1/2, retained messages, LWT
- USB — CDC ACM (virtual COM), HID, MSC (mass storage), DFU (firmware update)
- Ethernet — TCP/IP stack (lwIP), HTTP/HTTPS server, WebSocket, mDNS, SNTP
- I2C/SPI/UART — Sensor drivers, display interfaces, external memory, GPS/GSM modules
