Applications with Sequent Microsystems cards can be programmed using Open Source environments or dedicated drivers. The Open Source include Node-RED, OpenPLC, and Arduino. The functions of each card can be accessed using Command Line drivers and Python libraries.


1. Node-RED
Node-RED is a flow-based development tool for visual programming developed originally by IBM for wiring together hardware devices, APIs and online services as part of the Internet of Things. All Sequent cards can be controlled from Node-RED, either with native nodes or using the "exec" node calling the command line interface for each card


2. OpenPLC
OpenPLC is an open-source Programmable Logic Controller that is based on an easy to use software. It is the first fully functional standardized open source PLC, both in software and in hardware. OpenPLC Modules for multiple Sequent cards are available


3. Arduino
Arduino is an open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Since all Sequent HATs use only I2C for communication, we are developing drivers for accessing all our cards from the Arduino environment

Command Line

4. Command Line Interface
A command-line interpreter or command-line processor uses a command-line interface (CLI) to receive commands from a user in the form of lines of text. All the functions of Sequent Microsystems cards can be accessed from the command line. Open Source Command Line Interfaces are written in "C" and can be downloaded from GitHub


5. Python Libraries
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python consistently ranks as one of the most popular programming languages. Open Source Python Libraries for all Sequent Microsystems cards can be downloaded from GitHub
