// External libs
// We decided to put these libs inside the project folder, because we have a lot
// of issues with finding the right libs (some libs need a specific version, some
// libs have no unique name, some libs are broken, ...). This is not a fine
// software engineering practice, but it was too much of a hassle to get this right,
// so we decided to put everything in version control. This way, we also can control
// the version of the lib, which makes the build process of this project more
// robust to changes.
// IMPORTANT: You need to set the sketch location of your Arduino IDE to the firmware
// folder in order to use the libs. (File -> Preferences -> Sketchbook Location)

# Adafruit Unified Sensor Driver #
Many small embedded systems exist to collect data from sensors, analyse the data, and either take an appropriate action or send that sensor data to another system for processing.
One of the many challenges of embedded systems design is the fact that parts you used today may be out of production tomorrow, or system requirements may change and you may need to choose a different sensor down the road.
Creating new drivers is a relatively easy task, but integrating them into existing systems is both error prone and time consuming since sensors rarely use the exact same units of measurement.
By reducing all data to a single **sensors\_event\_t** 'type' and settling on specific, **standardised SI units** for each sensor family the same sensor types return values that are comparable with any other similar sensor. This enables you to switch sensor models with very little impact on the rest of the system, which can help mitigate some of the risks and problems of sensor availability and code reuse.
The unified sensor abstraction layer is also useful for data-logging and data-transmission since you only have one well-known type to log or transmit over the air or wire.
## Unified Sensor Drivers ##
The following drivers are based on the Adafruit Unified Sensor Driver:
**Accelerometers**
- [Adafruit\_ADXL345](https://github.com/adafruit/Adafruit_ADXL345)
- [Adafruit\_LSM303DLHC](https://github.com/adafruit/Adafruit_LSM303DLHC)
- [Adafruit\_MMA8451\_Library](https://github.com/adafruit/Adafruit_MMA8451_Library)
**Gyroscope**
- [Adafruit\_L3GD20\_U](https://github.com/adafruit/Adafruit_L3GD20_U)
**Light**
- [Adafruit\_TSL2561](https://github.com/adafruit/Adafruit_TSL2561)
- [Adafruit\_TSL2591\_Library](https://github.com/adafruit/Adafruit_TSL2591_Library)
**Magnetometers**
- [Adafruit\_LSM303DLHC](https://github.com/adafruit/Adafruit_LSM303DLHC)
- [Adafruit\_HMC5883\_Unified](https://github.com/adafruit/Adafruit_HMC5883_Unified)
**Barometric Pressure**
- [Adafruit\_BMP085\_Unified](https://github.com/adafruit/Adafruit_BMP085_Unified)
- [Adafruit\_BMP183\_Unified\_Library](https://github.com/adafruit/Adafruit_BMP183_Unified_Library)
**Humidity & Temperature**
- [Adafruit\_DHT\_Unified](https://github.com/adafruit/Adafruit_DHT_Unified)
## How Does it Work? ##
Any driver that supports the Adafruit unified sensor abstraction layer will implement the Adafruit\_Sensor base class. There are two main typedefs and one enum defined in Adafruit_Sensor.h that are used to 'abstract' away the sensor details and values:
**Sensor Types (sensors\_type\_t)**
These pre-defined sensor types are used to properly handle the two related typedefs below, and allows us determine what types of units the sensor uses, etc.
```
/** Sensor types */
typedef enum
{
SENSOR_TYPE_ACCELEROMETER = (1),
SENSOR_TYPE_MAGNETIC_FIELD = (2),
SENSOR_TYPE_ORIENTATION = (3),
SENSOR_TYPE_GYROSCOPE = (4),
SENSOR_TYPE_LIGHT = (5),
SENSOR_TYPE_PRESSURE = (6),
SENSOR_TYPE_PROXIMITY = (8),
SENSOR_TYPE_GRAVITY = (9),
SENSOR_TYPE_LINEAR_ACCELERATION = (10),
SENSOR_TYPE_ROTATION_VECTOR = (11),
SENSOR_TYPE_RELATIVE_HUMIDITY = (12),
SENSOR_TYPE_AMBIENT_TEMPERATURE = (13),
SENSOR_TYPE_VOLTAGE = (15),
SENSOR_TYPE_CURRENT = (16),
SENSOR_TYPE_COLOR = (17)
} sensors_type_t;
```
**Sensor Details (sensor\_t)**
This typedef describes the specific capabilities of this sensor, and allows us to know what sensor we are using beneath the abstraction layer.
```
/* Sensor details (40 bytes) */
/** struct sensor_s is used to describe basic information about a specific sensor. */
typedef struct
{
char name[12];
int32_t version;
int32_t sensor_id;
int32_t type;
float max_value;
float min_value;
float resolution;
int32_t min_delay;
} sensor_t;
```
The individual fields are intended to be used as follows:
- **name**: The sensor name or ID, up to a maximum of twelve characters (ex. "MPL115A2")
- **version**: The version of the sensor HW and the driver to allow us to differentiate versions of the board or driver
- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network
- **type**: The sensor type, based on **sensors\_type\_t** in sensors.h
- **max\_value**: The maximum value that this sensor can return (in the appropriate SI unit)
- **min\_value**: The minimum value that this sensor can return (in the appropriate SI unit)
- **resolution**: The smallest difference between two values that this sensor can report (in the appropriate SI unit)
- **min\_delay**: The minimum delay in microseconds between two sensor events, or '0' if there is no constant sensor rate
**Sensor Data/Events (sensors\_event\_t)**
This typedef is used to return sensor data from any sensor supported by the abstraction layer, using standard SI units and scales.
```
/* Sensor event (36 bytes) */
/** struct sensor_event_s is used to provide a single sensor event in a common format. */
typedef struct
{
int32_t version;
int32_t sensor_id;
int32_t type;
int32_t reserved0;
int32_t timestamp;
union
{
float data[4];
sensors_vec_t acceleration;
sensors_vec_t magnetic;
sensors_vec_t orientation;
sensors_vec_t gyro;
float temperature;
float distance;
float light;
float pressure;
float relative_humidity;
float current;
float voltage;
sensors_color_t color;
};
} sensors_event_t;
```
It includes the following fields:
- **version**: Contain 'sizeof(sensors\_event\_t)' to identify which version of the API we're using in case this changes in the future
- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network (must match the sensor\_id value in the corresponding sensor\_t enum above!)
- **type**: the sensor type, based on **sensors\_type\_t** in sensors.h
- **timestamp**: time in milliseconds when the sensor value was read
- **data[4]**: An array of four 32-bit values that allows us to encapsulate any type of sensor data via a simple union (further described below)
**Required Functions**
In addition to the two standard types and the sensor type enum, all drivers based on Adafruit_Sensor must also implement the following two functions:
```
bool getEvent(sensors_event_t*);
```
Calling this function will populate the supplied sensors\_event\_t reference with the latest available sensor data. You should call this function as often as you want to update your data.
```
void getSensor(sensor_t*);
```
Calling this function will provide some basic information about the sensor (the sensor name, driver version, min and max values, etc.
**Standardised SI values for sensors\_event\_t**
A key part of the abstraction layer is the standardisation of values on SI units of a particular scale, which is accomplished via the data[4] union in sensors\_event\_t above. This 16 byte union includes fields for each main sensor type, and uses the following SI units and scales:
- **acceleration**: values are in **meter per second per second** (m/s^2)
- **magnetic**: values are in **micro-Tesla** (uT)
- **orientation**: values are in **degrees**
- **gyro**: values are in **rad/s**
- **temperature**: values in **degrees centigrade** (Celsius)
- **distance**: values are in **centimeters**
- **light**: values are in **SI lux** units
- **pressure**: values are in **hectopascal** (hPa)
- **relative\_humidity**: values are in **percent**
- **current**: values are in **milliamps** (mA)
- **voltage**: values are in **volts** (V)
- **color**: values are in 0..1.0 RGB channel luminosity and 32-bit RGBA format
## The Unified Driver Abstraction Layer in Practice ##
Using the unified sensor abstraction layer is relatively easy once a compliant driver has been created.
Every compliant sensor can now be read using a single, well-known 'type' (sensors\_event\_t), and there is a standardised way of interrogating a sensor about its specific capabilities (via sensor\_t).
An example of reading the [TSL2561](https://github.com/adafruit/Adafruit_TSL2561) light sensor can be seen below:
```
Adafruit_TSL2561 tsl = Adafruit_TSL2561(TSL2561_ADDR_FLOAT, 12345);
...
/* Get a new sensor event */
sensors_event_t event;
tsl.getEvent(&event);
/* Display the results (light is measured in lux) */
if (event.light)
{
Serial.print(event.light); Serial.println(" lux");
}
else
{
/* If event.light = 0 lux the sensor is probably saturated
and no reliable data could be generated! */
Serial.println("Sensor overload");
}
```
Similarly, we can get the basic technical capabilities of this sensor with the following code:
```
sensor_t sensor;
sensor_t sensor;
tsl.getSensor(&sensor);
/* Display the sensor details */
Serial.println("------------------------------------");
Serial.print ("Sensor: "); Serial.println(sensor.name);
Serial.print ("Driver Ver: "); Serial.println(sensor.version);
Serial.print ("Unique ID: "); Serial.println(sensor.sensor_id);
Serial.print ("Max Value: "); Serial.print(sensor.max_value); Serial.println(" lux");
Serial.print ("Min Value: "); Serial.print(sensor.min_value); Serial.println(" lux");
Serial.print ("Resolution: "); Serial.print(sensor.resolution); Serial.println(" lux");
Serial.println("------------------------------------");
Serial.println("");
```

/*
This example connects to a WEP-encrypted Wifi network.
Then it prints the MAC address of the Wifi shield,
the IP address obtained, and other network details.
If you use 40-bit WEP, you need a key that is 10 characters long,
and the characters must be hexadecimal (0-9 or A-F).
e.g. for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work
(too short) and ABBAISDEAF won't work (I and S are not
hexadecimal characters).
For 128-bit, you need a string that is 26 characters long.
D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters,
all in the 0-9, A-F range.

WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.

If the IP address of your shield is yourAddress:
http://yourAddress/H turns the LED on
http://yourAddress/L turns it off
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.

* This function will be invoked when wlan device initialization should be

* The wifi device requires spi mode 3, i.e. clock polarity high and sample
* on second phase. This corresponds to CPOL=1, CPHA=1. Maximum frequency on
* spi clock is 30 MHz.
*
* The function is also responsible for doing any necessary spi initialization
* such as allocating gpio's, setting up the SPI master, one time allocations of
* dma buffers etc.
*
*
* If the SPB105 device is used, two signals; POWER (pin 10 on SPB105) and
* SHUTDOWN (pin 4 on SPB105) might be connected to gpio's on the host.
* The GPIO_POWER_PIN is the main power supply to the device. The
* GPIO_SHUTDOWN_PIN (active low) should be defined as an input.
*
* After GPIO_POWER_PIN is pulled high by the host, the device will pull the
* GPIO_SHUTDOWN_PIN high once the device is properly powered.
*
* However, if pin 4 (GPIO_SHUTDOWN_PIN) is not connected to the host, a delay
* of up to 250 ms must be added after GPIO_POWER_PIN is pulled high to ensure
* that startup is completed. The actual time is usually much shorter, therefore
* one might try to reduce the delay for a particualar hardware design.
*
* On SPB104, the GPIO_POWER_PIN will be connected to VCC and GPIO_SHUTDOWN_PIN
* will be unconnected; hence we have to make sure that we have enough delay
* after powering on the host. Since the device power-on usually happens at the
* same time as the host power-on, the startup time of the host can be
* subtracted from any delay put into owl_spi_init().

// As an interrupt may disappear while it is being fetched by the CPU
// (spurious interrupt caused by a delayed response from an MCU peripheral to
// an interrupt flag clear or interrupt disable instruction), check if there
// are remaining interrupt lines to process.
// If a spurious interrupt occurs, the status register (SR) contains an
// execution mode and interrupt level masks corresponding to a level 0
// interrupt, whatever the interrupt priority level causing the spurious
// event. This behavior has been chosen because a spurious interrupt has not
// to be a priority one and because it may not cause any trouble to other
// interrupts.
// However, these spurious interrupts place the hardware in an unstable state
// and could give problems in other/future versions of the CPU, so the
// software has to be written so that they never occur. The only safe way of
// achieving this is to always clear or disable peripheral interrupts with the
// following sequence:
// 1: Mask the interrupt in the CPU by setting GM (or IxM) in SR.
// 2: Perform the bus access to the peripheral register that clears or
// disables the interrupt.
// 3: Wait until the interrupt has actually been cleared or disabled by the
// peripheral. This is usually performed by reading from a register in the
// same peripheral (it DOES NOT have to be the same register that was
// accessed in step 2, but it MUST be in the same peripheral), what takes
// bus system latencies into account, but peripheral internal latencies
// (generally 0 cycle) also have to be considered.
// 4: Unmask the interrupt in the CPU by clearing GM (or IxM) in SR.
// Note that steps 1 and 4 are useless inside interrupt handlers as the
// corresponding interrupt level is automatically masked by IxM (unless IxM is
// explicitly cleared by the software).
//
// Get the right IRQ handler.
//
// If several interrupt lines are active in the group, the interrupt line with
// the highest number is selected. This is to be coherent with the
// prioritization of interrupt groups performed by the hardware interrupt
// controller.
//
// If no handler has been registered for the pending interrupt,
// _unhandled_interrupt will be selected thanks to the initialization of
// _int_line_handler_table_x by INTC_init_interrupts.
//
// exception.S will provide the interrupt handler with a clean interrupt stack
// frame, with nothing more pushed onto the stack. The interrupt handler must
// manage the `rete' instruction, what can be done thanks to pure assembly,
// inline assembly or the `__attribute__((__interrupt__))' C function

/*! \brief Automatically configure the CPU, PBA, PBB, and HSB clocks
*
* This function needs some parameters stored in a pcl_freq_param_t structure:
* - main_clk_src is the id of the main clock source to use,
* - cpu_f and pba_f and pbb_f are the wanted frequencies,
* - osc0_f is the oscillator 0's external crystal (or external clock) on-board frequency (e.g. FOSC0),
* - osc0_startup is the oscillator 0's external crystal (or external clock) startup time (e.g. OSC0_STARTUP).
* - dfll_f is the target DFLL frequency to set-up if main_clk_src is the dfll.
*
* The CPU, HSB and PBA frequencies programmed after configuration are stored back into cpu_f and pba_f.
*
* \note: since it is dynamically computing the appropriate field values of the
