For Firmware

Embedder reads your datasheets, writes the code, flashes the board, runs the tests, and fixes its own mistakes — autonomously.

Embedder is an AI agent for firmware. It reads your datasheets, writes the code, flashes the board, runs the tests, and fixes its own mistakes — autonomously. The platform supports 500+ MCUs and 3,000+ peripherals out of the box, including STM32, ESP32, nRF52/nRF91, NXP, Infineon, Microchip, Renesas, Silicon Labs, and RISC-V families. Every generated line is grounded in reference manuals, datasheets, schematics, and errata.

Unlike generic AI coding tools, Embedder is grounded in the actual constraints of the target system — register definitions, peripheral behavior, precise timing, and hardware-aware validation. Core capabilities include datasheet intelligence with cited generation, schematic ingestion across Altium, KiCad, Eagle, PADS, and Xpedition, hardware interaction over real debug probes, logic analyzers, power profilers, and oscilloscopes, and agent orchestration that fans out parallel specialized subagents into a build/flash/test/fix closed loop.

Core workflows include specification-first development, accelerated hardware bring-up, peripheral and driver implementation, rapid debugging and root cause analysis, iterative refinement and re-validation, and hybrid simulation and lab validation. Solutions span rapid prototyping, automated HIL and SIL, debugging and root-cause analysis, codebase modernization, platform migrations, and tailored deployments for startups and mid-market firmware teams.

Embedder ships as a managed Design Service, a VS Code extension, and a full-featured command-line tool — all backed by the same hardware-aware agent. It integrates natively with 30+ pieces of test equipment, including J-Link, ST-Link, OpenOCD, and GDB debug probes, Saleae and Digilent logic analyzers, Nordic PPK and Joulescope power profilers, and Siglent and Rigol bench equipment. Deployment options include Managed SaaS, Customer VPC, and On-Premises and Air-Gapped configurations, backed by SOC 2 Type II, ISO 27001, and GDPR-aligned controls. Piloted by industry leaders across semiconductors, IoT, medical technology, automotive, and aerospace/defense.

Datasheet Intelligence

Every line of generated code cites the reference manual section it came from. No hallucinated registers. No invented clock trees.

How do I configure USART2 for 9600 baud on STM32F407?

Set USART2->BRR = 0x1117. PCLK1 runs at 42 MHz, so USARTDIV = 42 MHz / (16 × 9 600) ≈ 273.44 → mantissa 273, fraction 7/16. Per Table 136 in RM0090 (§30.6.3), this produces an error of +0.02%.

Baud rate generation

The baud rate for the receiver and transmitter (Rx and Tx) are both set to the same value as programmed in the Mantissa and Fraction values of USARTDIV.

Tx/Rx baud = fCK / (8 × (2 − OVER8) × USARTDIV)

USARTDIV is an unsigned fixed-point number coded on the USART_BRR register:

  • The 12-bit mantissa of USARTDIV is programmed in the DIV_Mantissa[11:0] bits of USART_BRR.
  • The fraction of USARTDIV is programmed in the DIV_Fraction[3:0] bits. When OVER8 = 1, bit DIV_Fraction[3] must be cleared.
  • After writing a new value in USART_BRR the baud counter is replaced by the new one. The new value therefore takes effect at the next byte transfer.

Hardware Interaction

Embedder drives the test equipment your team owns — debug probes, logic analyzers, power profilers, oscilloscopes — and folds the signals back into the loop.

Runtime visibility without leaving the session

Embedder reads serial output and drives GDB sessions, stepping breakpoints, inspecting registers and memory, and correlating runtime state with the code under review. Failures get diagnosed against what the chip actually did, not what the source implied.

Electrical measurements as engineering context

Embedder turns logic analyzer captures and oscilloscope waveforms into structured data. Timing violations, protocol errors, and signal integrity issues surface as reviewable evidence, grounding firmware changes in the electrical behavior of the bus.

Agent Orchestration

Embedder coordinates multiple specialized agents that build, flash, test, and repair firmware in a closed loop — turning multi-hour workflows into minutes.

Divide complex tasks across specialized agents

Embedder decomposes multi-step firmware tasks into parallel subagent work streams that execute concurrently and merge their results.

EMBEDDER vs Generic AIspecialized agents

Build, flash, test, fix — autonomously

The orchestrator chains compilation, flashing, runtime observation, and code repair into a tight loop. When a test fails the agent diagnoses the fault, patches the source, and re-validates without human intervention.
