Now onboarding embedded teams

Ship compliant embedded products in half the time.

EmByte is the AI coding platform built only for embedded firmware. It writes MISRA-compliant C, diagnoses hard faults, and understands the exact MCU you're building on, from STM32 to ESP32 to nRF52.

MISRA C:2012

Rule 21.3 · Required

Dynamic memory is not allowed

malloc()can fragment the heap and fail non-deterministically, which is why it's banned in safety-critical firmware.

Suggested fix

static uint16_t buffer[SENSOR_MAX];

Apply fix

A real MISRA C:2012 violation, caught, explained, and fixed as you type.

Capabilities

One platform for the whole embedded workflow.

Compliance, debugging, hardware-aware coding, and codebase intelligence, all built for firmware from the ground up rather than adapted from web dev.

Compliance

MISRA compliance, without the pain.

Real-time violation detection as you code. Every rule explained in plain English. Auto-fix what can be fixed, and track deviations with an auditable workflow, not a spreadsheet.

Debugging

Debug in minutes, not days.

Paste a fault address. EmByte reads your registers and points to the root cause.

Coding

AI that knows your MCU.

Completion that understands STM32 HAL, ESP-IDF, and nRF SDK, and never breaks an ISR.

Intelligence

Understand any codebase in hours.

Ask questions about legacy code in plain English. Answers are grounded in your real hardware: peripherals, clock trees, and RTOS task structure.

QWhat does signal_controller_task do?
AFreeRTOS task at priority 5. Reads interlocking commands from CAN, drives the signal output GPIOs. Fail-safe timeout: 2 s.

Hardware-aware

EmByte sees your whole chip.

Before it writes a line, EmByte builds a complete model of your MCU: every peripheral, register, clock, and interrupt. That's why the code it generates compiles and runs the first time, instead of guessing at register addresses.

UARTSPII²CCANGPIOADCTimersDMAEMBYTE-INDEXEDMCUregisters · clocks · IRQs

Reads your datasheet

It reads your reference manuals, errata, and pin maps, so every line it generates traces back to a real source.

Maps every register

It models every peripheral, memory region, and bit field, so register addresses are never hallucinated.

Knows the clock tree

It checks clock configuration, prescalers, and interrupt priorities before it writes a single line.

Case study

Proven on a national-railway deployment.

A railway signalling OEM needed a full MISRA-compliant embedded system for a national rail network: safety-critical, with zero tolerance for failure and a fixed 60-day window. EmByte delivered the firmware, drivers, and compliance evidence.
