Constant Data

Each script has a global variable called

DEVICE

that is available from anywhere in the code. They contain constant data about the current device. When using an emulator, this variable contains applicable messages about lack of support.

DEVICE

is described by the following type:

interface IDevice {
 hostname: string;
 model: string;
 part_number: string;
 serial_number: string;
 uuid: string;
 firmware_version: string;
 type: DeviceType;
 sensor: ISensor;
 gpio: IGPIO;
}

Using the following types:

enum DeviceType {
  REAL = "REAL",
  EMULATED = "EMULATED",
}

enum GpioPortState {
  DISABLE = "DISABLE",
  TRIGGER = "TRIGGER",
  JOB_SWITCH = "JOB_SWITCH",
  ILLUMINATION_STROBE = "ILLUMINATION_STROBE",
  INPUT = "INPUT",
  OUTPUT_PUSH_PULL = "OUTPUT_PUSH_PULL",
  OUTPUT_HIGH_SIDE = "OUTPUT_HIGH_SIDE",
  OUTPUT_STATIC_HIGH = "OUTPUT_STATIC_HIGH",
  OUTPUT_STATIC_LOW = "OUTPUT_STATIC_LOW",
  OUTPUT = "OUTPUT",
}

interface IGPIOPort {
  number: number;
  state: IGpioPortState;
}

interface IGPIO {
  count: number;
  ports: IGPIOPort[];
}

interface ISensor {
  sensor_type: string;
  width: number;
  height: number;
}
