I2C Converter with Dual Serial to 8-Port Hardware I2C

The Ultimate Serial to I2C Converter Adapter

Introducing the world’s most powerful and expandable Serial to I2C Converter.  With Eight nodeLynk I2C Expansion Ports and Two Interchangeable Communications Ports compatible with Digi XBee®, this powerful I2C adapter offers the highest possible conversion speed with the most efficient command set available.  Communications modules may be interchanged for your choice of communication requirements.  Based on the endNode architecture, this controller provides an excellent platform to help simplify communications to otherwise complex I2C devices.  Over a year in development, this device served as the development platform for our endNodes architecture, which includes an incredible command set for relay control, far beyond I2C conversion.  New features include hardware I2C communications now supporting speeds up to 700KHz.  Set the communications speed of each nodeLynk I2C Port as part of Device Configuration.  This device now includes a new command set that simplifies read and write operations to I2C devices.  New I2C Bus Scan functions scans and reports all detected devices on each I2C port in less than 1 Second.

An I2C Converter with Brains: endNode Architecture & ProXR Enterprise

We’ve also added ProXR Enterprise to the command set, which is our most powerful relay control command set to date.  Capable of controlling up to 1,024 relays using 8 nodeLynk I2C ports, this is our most expandable relay controller we have ever manufactured. Designed to work with all MCP23008 and MCP23017 I2C Relay Controllers, ProXR Enterprise adds powerful commands for turning relays on or off, toggling the state of relays, pulsing relays, and controlling relays in groups.  ProXR Enterprise also offers powerful relay timer capabilities to activate relays for a duration of time or to trigger different commands when timers finish their counting cycle.  Integrated Macros make it possible to send a simple command to execute a list of up to eight commands in the background.  Powerful startup functions allow you to execute commands when power is first applied to the controller in addition to complete power-up relay state control.  Integrated Non-Volatile FRAM memory allows unlimited read/write capabilities without memory degradation and no battery backup required.  FRAM memory keeps track of relay status, timers, macros, and many important system settings.  New Relay Counters control relays in patterns using Counter Increase and Decrease functions.  Relay Counters can be used for efficient lighting control, emergency lighting, or signage applications.  Automatic and Manual Relay Refresh Modes allow you to send relay control commands without affecting relays.  When you ready, simply send a refresh command and refresh every relay connected to the controller.

Bluetooth to I2C Conversion

Bluetooth to I2C Conversion requires the use of the WiFi option during checkout, users may choose to use the WiFi, Bluetooth, or USB communications technologies by using a single WiFi module that integrates all three technologies into a single communications module.

Ethernet and WiFi to I2C Conversion

Network communications could not be any easier.  Simply associate this device with your network using WiFi (2.4GHz Only) or a Ethernet cable connected directly to your router, open TCP socket 2101 and start sending and receiving TCP data.  Both Ethernet and WiFi options support DHCP, Programmable TCP Port, and a Programmable Static IP address.  Both communication options also support web page configuration of communication technologies.  The WiFi Option Supports WiFi TCP/IP and WiFi MQTT Communications.

MQTT Over WiFi

Our nodeLynk I2C Converter becomes a internet controlled device when using the WiFi option.  Paired with our new WiFi communications module, the MQTT communications option may be used, allowing this device to talk directly to MQTT servers using a single publish and subscribe topic used for transporting low-level I2C messages.  This effectively allows any command to be executed via MQTT communications for remote operation from anywhere in the world.

I2C Converter Re-Engineered

This device acts has a hardware dual port serial to master hardware I2C protocol converter designed to communication with NCD nodeLynk I2C node devices.  I2C Master controllers initiate communications to node devices such as ADC, DACs, Potentiometers, PWM controllers, GPIO controllers, and a wide variety of sensors.  I2C node devices are always speak when spoken to, they do NOT initiate communications with a master I2C controller.  Conversion works by sending a single hardware I2C port selection along with a I2C start address as well as any associated parameters, as well the number of bytes you would like to request from the I2C device.  The I2C converter will exchange all data and report the response from the I2C device via a serial format.  The term “hardware” is used to indicate that dedicated hardware is used for all serial and I2C communications.  This device does NOT use a virtual serial ports or I2C ports which would greatly limit communications speed.  Instead, this device uses dedicated hardware peripherals for all communications to greatly enhance speed and reliability of communications.  The term “master” is used to indicate this device will initiate communications with a node.  It is not possible for a node to initiate communications with a master, as this is not supported in the I2C protocol.

This device now includes more powerful commands that execute faster than previous generation controllers including I2C Bus Scan, used to displays all devices connected to a nodeLynk I2C port.  New I2C converter commands for I2C Write, I2C Read, and I2C Write/Read operations, which are now executed using hardware I2C ports rather than software emulated ports found in previous generation controllers.  The new hardware I2C ports offer I2C Bus Speeds up to 700KHz per nodeLynk I2C Port.  I2C Port Switching and Communications is now executed as a single command, offering incredible speed for switching ports and executing read/write operations with a single transaction.

Designed with Visual Studio in Mind

The NCD WiFi to I2C Converter is a perfect companion to add automation, sensing, monitoring, and control features to Visual Studio applications.  We are always improving our Alpha Station Software framework, which includes all libraries needed to communicate to every kind of I2C sensor and controller imaginable.  Simple libraries for I2C Read, Write, and Write Read operations make it easy to talk to all kinds of hardware with minimal time investment.  Talk to displays, sensors, multiplexers, relay controllers, pulse width modulators, and more.  The Alpha Station framework is ready to go to work monitoring and controlling using Visual Studio Community Edition (free from Microsoft.com).

Control LCD Displays with Visual Studio

Alpha Station provides you with a working sample framework, take a look at the source code to see how easy it is to control this display:

Read MAX1069 Analog to Digital Converters with Visual Studio

Alpha Station gives you the tools you need to quickly read and display Analog to Digital Values such as the MAX1069 connected to a 8-Channel Multiplexer to display the result.  Reading and Displaying ADC Values could not get any easier.  Notice how we use the I2C Write Read Command to talk to the MAX1069 with a start address of &H37, this command handles all the low-level I2C communications to the chip, you simply specify the start address, number of bytes you would like to read (2), and the delay (0) between the Write and Read operation.  When the chip returns a response, it should be 2 bytes in Length.  The response is then converted to a 14-Bit value using the NCDLib.Math.MSLBLS14 command.  The value can then be displayed directly to the console.

Control a AS1115 LED Display with Visual Studio

Alpha Station Libraries make it easy to control hardware.  The AS1115 Library is used to communicate numeric values directly to a LED display.  Values from 0 to 999 are supported as well as brightness levels of 0 to 15.  Simple library calls are all it takes to setup a dedicated hardware numeric display.
