General Information

Allows to perform operations with serial connected devices.

Includes following features:

  • Retrieve latest sensor data(raw, full, infrared, visible)
  • Retrieve meta information from the internal board state
  • Modify settings for the light sensor.

All the operations are perform with the usage of ProtocolBuffers.

Setup

Your board needs to have already installed software build, which allows communication with TSL2591X device. The device should be connected.

All setup related operations are processed via Makefile placed in the root directory.

In order to build the project it's required to execute the following command. It generates local Python project.

make install

Use Cases

Most of the commands given below require baud rate. It is important to be the exact-supported value, otherwise requests will be ignored(in the given examples baud rate is equal to 9600).

Get Available Devices

The example below shows how to retrieve a set of all available devices, which can be used to perform other operations.

$ light-detector-cli get_available_devices

[
  instance(AvailableDevicesDto):
    description: 'STM32 STLink',
    location: '/dev/cu.usbmodem1203',
    manufacturer: 'STMicroelectronics'
]

Get Info

The examples below show all the possible ways to retrieve metadata information from the board. Baud rate is important to be the exact-supported value, otherwise requests will be ignored(in the given examples baud rate is equal to 9600).

Gain

The next example shows how to retrieve the value of gain metadata information from the board.

$ light-detector-cli get_info --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="gain"

instance(RetrievedInfoDto):
  data_type: <InfoTypeCompound.GAIN: 'Gain'>,
  device_id: 80,
  nonce: 4,
  value: 16

Available gain values:

  • 0 - low
  • 16 - medium
  • 32 - high
  • 48 - max

Integral Time

The next example shows how to retrieve the value of integral time metadata information from the board.

$ light-detector-cli get_info --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="integral_time"

instance(RetrievedInfoDto):
  data_type: <InfoTypeCompound.INTEGRAL_TIME: 'IntegralTime'>,
  device_id: 80,
  nonce: 5,
  value: 1

Available integral time values:

  • 0 - 100ms
  • 1 - 200ms
  • 2 - 300ms
  • 3 - 400ms
  • 4 - 500ms
  • 5 - 600ms

Processed Requests

The next example shows how to retrieve the value of processed requests(amount of successful incoming requests, different from nonce) metadata information from the board.

$ light-detector-cli get_info --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="processed_requests"

instance(RetrievedInfoDto):
  data_type: <InfoTypeCompound.PROCESSED_REQUESTS: 'ProcessedRequests'>,
  device_id: 80,
  nonce: 6,
  value: 20

Device Available

The next example shows how to retrieve the value of device available metadata information from the board.

$ light-detector-cli get_info --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="device_available"

instance(RetrievedInfoDto):
  data_type: <InfoTypeCompound.DEVICE_AVAILABLE: 'DeviceAvailable'>,
  device_id: 80,
  nonce: 7,
  value: 1

Available device available values:

  • 1 - device available
  • 0 - device is not available

Set settings

The examples below show all the possible ways to modify device settings. Baud rate is important to be the exact-supported value, otherwise requests will be ignored(in the given examples baud rate is equal to 9600).

Successful operation will be signalized with LED blinking.

Reset

The next example shows how to reset all the settings of the device

$ light-detector-cli set_settings --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="reset"

instance(SetSettingsDto):
  device_id: 80,
  nonce: 5,
  result: True,
  settings_type: <SettingsTypeCompound.RESET: 'Reset'>

Set Gain

The next example shows how to modify gain setting of the device.

$ light-detector-cli set_settings --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="set_gain" --value="low"

instance(SetSettingsDto):
  device_id: 80,
  nonce: 7,
  result: True,
  settings_type: <SettingsTypeCompound.SET_GAIN_LOW: 'SetGainLow'>

Available set_gain values:

  • low - 0
  • medium - 16
  • high - 32
  • max - 48

Set Integral Time

The next example shows how to modify integral time setting of the device.

$ light-detector-cli set_settings --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="set_integral_time" --value="first"

instance(SetSettingsDto):
  device_id: 80,
  nonce: 8,
  result: True,
  settings_type: <SettingsTypeCompound.SET_INTEGRAL_TIME_FIRST: 'SetIntegralTimeFirst'>

Available set_integral_time values:

  • first - 100ms
  • second - 200ms
  • third - 300ms
  • forth - 400ms
  • fifth - 500ms
  • sixth - 600ms

Get data

The examples below show all the possible ways to retrieve data information from the board.

$ light-detector-cli get_data --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="raw"

[
  instance(RetrievedDataDto):
    data_type: <DataTypeCompound.RAW: 'Raw'>,
    device_id: 80,
    nonce: 4,
    value: 121
]

In the same way other types of data can be retrieved, all the available data types are given below:

  • raw
  • full
  • infrared
  • visible

It's also possible to have a series of measurements, in order to archive that it's important to add series parameter.

$ light-detector-cli get_data --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="raw" --series=4

[
  instance(RetrievedDataDto):
    data_type: <DataTypeCompound.RAW: 'Raw'>,
    device_id: 80,
    nonce: 26,
    value: 51
  instance(RetrievedDataDto):
    data_type: <DataTypeCompound.RAW: 'Raw'>,
    device_id: 80,
    nonce: 27,
    value: 80
  instance(RetrievedDataDto):
    data_type: <DataTypeCompound.RAW: 'Raw'>,
    device_id: 80,
    nonce: 28,
    value: 97
  instance(RetrievedDataDto):
    data_type: <DataTypeCompound.RAW: 'Raw'>,
    device_id: 80,
    nonce: 29,
    value: 41
]

Having a series of measurements it becomes possible to create a diagram to more easily observe output changes. In order to do that it's needed to add export(describes a location of output diagram file) and figure(describes a type of the diagram) parameters.

$ light-detector-cli get_data --device="/dev/cu.usbmodem1203" --baud_rate="9600" --type="raw" --series=4 --export="./output" --figure="plot"

...

Available figure values:

  • plot
  • stairs
  • scatter
