ADS7830

CircuitPython driver for the ADS7830 analog to digital converter

• Author(s): Liz Clark

Implementation Notes

Hardware:

• Adafruit ADS7830 8-Channel 8-Bit ADC with I2C

Software and Dependencies:

• Adafruit CircuitPython firmware for the supported boards: https://circuitpython.org/downloads

• Adafruit’s Bus Device library: https://github.com/adafruit/Adafruit_CircuitPython_BusDevice

class adafruit_ads7830.ads7830.ADS7830(i2c: busio.I2C, address: int = _I2C_ADDR, differential_mode: bool = False, int_ref_power_down: bool = False, adc_power_down: bool = False)

Adafruit ADS7830 ADC driver

Initialization over I2C

Parameters:

• address (int) – I2C address (default 0x48)

• differential_mode (bool) – Select differential vs. single mode

• int_ref_power_down (bool) – Power down internal reference after sampling

• adc_power_down (bool) – Power down ADC after sampling

read(channel: int) → int

ADC value Scales the 8-bit ADC value to a 16-bit value

Parameters:

channel (int) – Channel (0-7)

Returns:

Scaled ADC value or raise an exception if read failed

Return type:

int
