Installation

Download the firmware using git:

git clone https://github.com/open-storm/perfect-cell.git

Open perfect-cell.cyprj using PSoC Creator (4.1 or greater).

Configure your firmware to match your server settings (see below), then build the project.

Use PSoC Creator to flash the firmware to a compatible device.

Telemetry

Telemetry via influxdb

First, set up a remote server to receive data from the sensor node.

Set the following parameters in config.h to match your server settings:

// Service to use
#define USE_INFLUXDB        1
#define USE_CHORDS          0

...

// Default user info
#define DEFAULT_HOME_USER   "home_user"
#define DEFAULT_HOME_PASS   "home_pass"
#define DEFAULT_HOME_DB     "HOME_DB"
#define DEFAULT_HOME_PORT   8086
#define DEFAULT_HOME_HOST   "your-ec2-instance-here.com"

// Meta user info
#define DEFAULT_META_USER   "meta_user"
#define DEFAULT_META_PASS   "meta_pass"
#define DEFAULT_META_DB     "META_DB"
#define DEFAULT_META_PORT   8086
#define DEFAULT_META_HOST   "your-ec2-instance-here.com"

...

// SSL parameters
#define SSL_ENABLED            1u

Telemetry via CHORDS

Data can be transmitted remotely to a CHORDS portal. Currently, bidirectional communication with the CHORDS portal is not supported.

Set the following parameters in config.h to match your server settings:

// Service to use
#define USE_INFLUXDB        0
#define USE_CHORDS          1

...

#define CHORDS_HOST                "your-portal.chordsrt.com"
#define CHORDS_PORT                80
#define CHORDS_INSTRUMENT_ID       1
#define CHORDS_WRITE_KEY_ENABLED   1
#define CHORDS_WRITE_KEY           "key"
#define CHORDS_IS_TEST             0

...

// SSL parameters
#define SSL_ENABLED            0u

Overview

The perfect-cell firmware contains a simple operating system that performs the following routines at a recurring interval.

• ''wakes'' the board from sleep mode
• takes measurements using the attached sensors
• connects to the cellular network
• sends sensor data to a web server
• updates device metadata and onboard parameters
• triggers attached actuators
• puts the board back into sleep mode.

An overview of the firmware can be found in the open-storm docs.

Auto-generated doxygen documentation can also be found here.

Schematics for the board can be found here.
