Technical Change Note – Bootloader (SAMD21)

For the Hebabox and Hebastack, a modified version of the Arduino SAMD21 bootloader is used.

The modification is deliberately minimal and affects only one file: bootloaders/zero/main.c

In this file, an additional security routine has been integrated: security_bit_check_and_set()

Purpose of this modification:
Checks during boot whether the SAMD21 Security Bit (SSB) is already set
Automatically sets the SSB if it is not yet activated
Ensures that the microcontroller cannot be read out without a full chip erase
Provides reliable firmware protection for the Hebabox / Hebastack
The application firmware itself is not affected by this modification and remains fully proprietary.

What is the difference between Digital I/O and Modbus TCP for EoL testing with Hebabox / Hebastack ?2026-02-01T15:55:19+01:00

Both Digital I/O and Modbus TCP can be used to integrate Hebabox / Hebastack into an End-of-Line (EoL) test system. The key difference lies in functionality, data depth, and scalability.


Digital I/O (discrete signals)

With Digital I/O, the Hebabox/Hebastack is controlled via simple binary signals (24 V inputs/outputs).

Typical use cases

  • Start / stop a test cycle

  • Reset

  • Output overall status signals such as Busy, OK, or NOK

Characteristics

  • Very simple and robust

  • No Ethernet or network configuration required

  • Limited to ON/OFF signals

  • No parameterization, detailed diagnostics, or measurement data transfer

  • Ethernet hardware is not required

Best suited for

  • Very simple EoL setups

  • Legacy systems

  • Applications with minimal functional requirements


Modbus TCP (Ethernet-based communication)

With Modbus TCP, the Hebabox/Hebastack communicates with the PLC via Ethernet using structured data registers.

Typical use cases

  • Start / stop and full control of test sequences

  • Parameterization (e.g. light values, modes, sequences)

  • Reading detailed status, diagnostics, and error codes

  • Logging and traceability in production systems

Characteristics

  • Significantly higher functional depth

  • Structured data exchange instead of single bits

  • Scalable and future-proof

  • Enables detailed diagnostics and transparency

  • Requires Ethernet connection and PLC-side Modbus implementation

Best suited for

  • Modern EoL production lines

  • Automated test systems with traceability requirements

  • OEM / Tier-1 environments


Which option do we recommend?

While both options are supported, we clearly promote Modbus TCP for EoL testing:

  • Higher functional value

  • More diagnostic and test content

  • Better scalability

  • Preferred and approved interface in BMW production environments

Digital I/O remains an option for minimal setups, but Modbus TCP is the recommended choice for professional, production-grade EoL testing with Hebabox and Hebastack.

 

 

 

Why does Hebatronic not offer LIN-based solutions?2026-01-29T16:00:37+01:00

Hebatronic deliberately does not offer LIN-based solutions because LIN is not technically suited for modern ILaS® / ISELED® lighting systems beyond basic control functions.

LIN was designed as a low-speed control bus for simple actuators and sensors. With a maximum data rate of approximately 20 kbit/s, LIN is well suited for commands such as on/off, dimming, or basic status signals. However, it reaches its technical limits very quickly when used for today’s dynamic, high-resolution LED lighting systems.

Modern ILaS® / ISELED® applications require:

  • High bandwidth for color and brightness data

  • Deterministic timing for synchronized animations

  • Scalability to hundreds or thousands of LEDs

  • Detailed diagnostic feedback at LED level

These requirements are structurally incompatible with LIN. Using LIN as a transport layer for ILaS® functions inevitably leads to compromises in performance, diagnostics, flexibility, and scalability.

Hebatronic therefore focuses on ILaS-native architectures, where lighting data is handled directly on the ILaS® bus and controlled via industrial, deterministic interfaces (e.g. PLC-based systems). This avoids inheriting the technical limitations of LIN and allows the full capabilities of ILaS® to be used without restriction.

In short:

  • LIN is suitable for controlling simple lighting functions.

  • ILaS® is required for driving complex, modern LED lighting systems.

  • Hebatronic designs its solutions around the requirements of ILaS®, not around the limitations of LIN.

This is a conscious architectural decision to ensure long-term scalability, diagnostic depth, and production robustness.

 

 

What is the difference between LIN and ILaS®?2026-01-29T14:48:52+01:00

LIN (Local Interconnect Network) and ILaS® (Intelligent Lighting as a Service) are two fundamentally different communication systems used in vehicles, each designed for a specific purpose.

LIN is a classic, low-cost control bus. It was developed for simple actuators and sensors such as switches, motors, and basic lighting functions. LIN operates at a relatively low data rate and is mainly used to transmit control commands like on/off, dimming, or simple status information.

ILaS®, in contrast, is a high-speed bus specifically designed for modern LED lighting systems. It is optimized for ISELED®-based light modules and transmits synchronized color and brightness data to each individual LED in a chain. In addition, ILaS® enables detailed diagnostic feedback from every LED.

In short:

  • LIN is a control bus for simple functions.

  • ILaS® is a data bus for complex, dynamic LED lighting.

Key differences at a glance:

  • Data rate:
    LIN ≈ 20 kbit/s · ILaS® ≈ 2 Mbit/s

  • Typical use:
    LIN → basic control commands
    ILaS® → high-resolution lighting data and animations

  • Scalability:
    LIN → limited number of nodes
    ILaS® → thousands of LEDs in a single chain

  • Diagnostics:
    LIN → basic
    ILaS® → detailed, per-LED diagnostics

In modern vehicle and EOL test architectures, both systems are often used together:
LIN provides the higher-level control or test interface, while ILaS® handles the precise distribution, synchronization, and diagnostics of the lighting system.

Yes, the Hebabox/Hebastack is scalable and future-proof. It comes with the current Hebatronic software and can be flexibly extended for future ISELED® generations.

Can the Hebabox/Hebastack be used in EOL test benches?2026-02-01T16:01:57+01:00

Yes. Hebabox and Hebastack are specifically designed for use in automated End-of-Line (EoL) test systems and are intended for series production environments.

They act as a robust, PLC-integrated gateway between the test system and the ILaS® / ISELED® bus, enabling deterministic and reproducible testing under real production conditions.

Typical EoL test functions include:

  • Deterministic initialization of the ILaS® bus

  • Automatic node detection (node count / presence check)

  • Verification of communication integrity and timing

  • Evaluation of module status and error conditions

  • Functional activation of light modules for GO / NO-GO decisions

Integration into the test system

  • PLC connection via Modbus TCP (recommended for maximum functionality and diagnostics)

  • Alternatively via Digital I/O for simple, minimal EoL setups

  • Clear separation between test logic (PLC) and gateway functionality (Hebabox / Hebastack)

Production and OEM readiness

  • Designed for continuous operation in production lines

  • Scalable to different test depths and requirements

  • Used and approved in OEM and Tier-1 EoL environments (e.g. BMW)

In short:
Hebabox and Hebastack are not laboratory tools — they are production-grade EoL components that integrate seamlessly into modern, PLC-controlled test systems.
