Arduino library for Sequent Microsystems Sixteen Analog/Digital Inputs 8-Layer Stackable HAT for Raspberry Pi
Go to Tools>>Manage Libraries.. menu and search for SM_16UNIVIN and click install
To download click <>Code > Download ZIP button from the main page, rename the uncompressed folder to "SM_16univin" and copy to the libraries subdirectory of your sketchbook directory ("This PC > Documents > Arduino > libraries" for a Windows PC or "Home > arduino > libraries" on Linux PC). Now launch the Arduino environment. If you open the Sketch > Include Library menu, you should see Sequent 16univin inside. The library will be compiled with sketches that use it. Open an arduino sketch, go to File > Examples > Seqquent 16univin > and chose your example to run.
There are three ways to control the Sexteen Universal Inputs Card from the Arduino environment.
You can use this method with any Arduino card with an I2C port by connecting I2C-SDA, I2C-SCL, +5V and GND, as shown in the following table.
| SIGNAL | PIN# | CONN | PIN# | SIGNAL |
|---|---|---|---|---|
| --1 | O - O | 2-- | +5V | |
| I2C-SDA | --3 | O - O | 4-- | +5V |
| I2C-SCL | -- 5 | O - O | 6-- | GND |
| -- 7 | O - O | 8-- | ||
| GND | -- 9 | O - O | 10-- | |
| --11 | O - O | 12-- | ||
| --13 | O - O | 14-- | GND | |
| --15 | O - O | 16-- | ||
| --17 | O - O | 18-- | ||
| --19 | O - O | 20-- | GND | |
| --21 | O - O | 22-- | ||
| --23 | O - O | 24-- | ||
| GND | --25 | O - O | 26-- | |
| --27 | O - O | 28-- | ||
| --29 | O - O | 30-- | GND | |
| --31 | O - O | 32-- | ||
| --33 | O - O | 34-- | GND | |
| --35 | O - O | 36-- | ||
| --37 | O - O | 38-- | ||
| GND | --39 | O - O | 40-- |
Sequent Microsystems Arduino Uno, Nano, Teensy, Feather or ESP32 Raspberry Pi Replacement Kit is an inexpensive adapter which can be used to control any of our HATs using Uno, Nano, Teensy, Feather or ESP32. Plug the Home Automation HAT into the 40 pin connector of the adapter and write your Arduino software.
ESP32-Pi is a Raspberry Pi alternate solution which can control directly the Sexteen Universal Inputs HAT. In your sketchbook set the board type to DOIT ESP32 DEVKIT V1: Tool >> Board >> ESP32 Arduino >> DOIT ESP32 DEVKIT V1
