eFlow Visual Programming

Build Embedded Systems Visually

eFlow is EmbeddedOS's visual programming environment — drag, connect, and deploy firmware to 83 hardware targets without writing a single line of boilerplate.

From Idea to Deployed Firmware

The complete 8-step eFlow build and deploy pipeline.

Step 01

Hardware Design

Define your target hardware: MCU, peripherals, memory map, and pin assignments using the visual board designer.

Step 02

Driver Configuration

Select and configure drivers from the library: GPIO, UART, SPI, I2C, CAN, USB, and custom peripherals.

Step 03

RTOS Setup

Configure the EOS Kernel: task priorities, stack sizes, scheduling policy, and inter-task communication channels.

Step 04

Application Logic

Build your application logic using eFlow's visual block editor — no assembly required for common patterns.

Step 05

Build & Validate

ebuild compiles, links, and runs static analysis. EoSim validates the firmware against your hardware model.

Step 06

Simulate

Run full hardware simulation with EoSim: GPIO toggling, UART output, memory inspection, and CPU profiling.

Step 07

Deploy

Flash to real hardware via JTAG, SWD, or USB bootloader. Monitor with ebuild's integrated serial console.

Step 08

Monitor & Update

Use the eBoot OTA system for wireless updates. Monitor device health with the built-in telemetry stack.

Runtime Architecture

The layered architecture that powers every EmbeddedOS deployment.

eApps / EAI / ENI
Application layer: 60+ apps, AI inference, network services
EIPC
Inter-process communication: typed channels, message queues
EoS / eBoot
Core OS: real-time kernel, secure bootloader, hardware abstraction
Hardware
Target hardware: MCU, SBC, automotive ECU, x86 system

CI/CD Pipeline

Four quality gates ensure every build is production-ready.

Static Analysis
MISRA-C, CERT-C, and custom rule sets
Unit Tests
Hardware-in-the-loop and simulation-based testing
Integration Tests
Full system simulation with EoSim
Deploy
Automated OTA deployment with rollback support
