API

ain420.get_adc_raw16_value(1)

• Retrieves the 16-bit ADC raw value of the specified channel. This is an unprocessed digital signal representation read from the specified channel.

ain420.get_ain_current_value(1)

• Retrieves the current value of the specified channel. This is typically used to read data from current sensors, indicating the actual current value on the channel.

ain420.get_firmware_status()

• Retrieves the firmware version number of the device.

ain420.init_i2c_address(0x55)

• Initializes the I2C address of the device.

ain420.set_i2c_address(0x55)

• Sets the I2C slave address of the device.
