AS7265X MicroPython Driver

This is a MicroPython driver for the AS7265X 18-channel spectral sensor.

Usage Example

from machine import I2C
from AS7265X import AS7265X

# Initialize I2C (example for ESP32)
i2c = I2C(0, scl=Pin(22), sda=Pin(21))

# Initialize the sensor
sensor = AS7265X(i2c)

# Take a measurement
sensor.take_measurements()

# Get calibrated values
a_cal = sensor.get_calibrated_A()
b_cal = sensor.get_calibrated_B()
# ... and so on for all 18 channels

print(f"Calibrated A: {a_cal}")
print(f"Calibrated B: {b_cal}")

API

The driver provides the following methods:

• __init__(self, i2c, **kwargs): Initializes the sensor.
• virtual_read_register(self, virtual_address): Reads a virtual register.
• virtual_write_register(self, virtual_address, value): Writes to a virtual register.
• get_devicetype(self): Gets the device type.
• get_hardware_version(self): Gets the hardware version.
• get_major_firmware_version(self): Gets the major firmware version.
• get_patch_firmware_version(self): Gets the patch firmware version.
• get_build_firmware_version(self): Gets the build firmware version.
• take_measurements(self): Takes measurements for all channels.
• take_measurements_with_bulb(self): Turns on all bulbs, takes measurements, then turns off bulbs.
• get_G(self), get_H(self), ..., get_F(self): Get raw values for each channel.
• get_calibrated_A(self), get_calibrated_B(self), ..., get_calibrated_F(self): Get calibrated values for each channel.
• set_measurement_mode(self, mode): Sets the measurement mode.
• set_gain(self, gain): Sets the gain.
• set_integration_cycles(self, cyclevalue): Sets the integration cycle amount.
• enable_interrupt(self): Enables the interrupt.
• disable_interrupt(self): Disables the interrupt.
• data_available(self): Checks if data is available.
• clear_data_available(self): Clears the data available flag.
• enable_bulb(self, device): Enables the bulb on a given device.
• disable_bulb(self, device): Disables the bulb on a given device.
• set_bulb_current(self, current, device): Sets the current limit of the bulb/LED.
• select_device(self, device): Selects the device (master or slave).
• enable_indicator(self): Enables the onboard indicator LED.
• disable_indicator(self): Disables the onboard indicator LED.
• set_indicator_current(self, current): Sets the current limit of the onboard LED.
• get_temperature(self, devicenumber): Gets the temperature of a given device.
• get_temperature_average(self): Gets the average temperature of all sensors.
• soft_reset(self): Performs a soft reset.
• get_value(self, RorC): Gets all raw or calibrated values based on the argument.
