CHIP_IO.LRADC

The LRADC module handles interfacing with the onboard 6-Bit, 2V tolerant ADC in the R8/GR8.

Import the LRADC module as follows

  import CHIP_IO.LRADC as LRADC

toggle_debug()

Enable/Disable the Debug

• Parameters

  None

• Returns

  None

• Examples

  LRADC.toggle_debug()
  

get_device_exist()

Check to see if the LRADC device exists

• Parameters

  None

• Returns

  boolean - True if LRADC is enabled, False is LRADC is disabled

• Examples

  LRADC.get_device_exist()
  

setup(rate=250)

Setup the LRADC, defaults to a sampling rate of 250.

• Parameters

  rate (optional) - Sampling rate of the LRADC: 32.25, 62.5, 125, 250

• Returns

  boolean - True if LRADC is enabled, False is LRADC is disabled

• Examples

  LRADC.setup()
  LRADC.setup(32.25)
  

get_scale_factor()

Get the scaling factor applied to raw values from the LRADC

• Parameters

  None

• Returns

  float - scale factor applied to the LRADC Raw data

• Examples

  factor = LRADC.get_scale_factor()
  print(factor)
  

get_allowable_sample_rates()

Get the allowable sample rates for the LRADC

• Parameters

  None

• Returns

  tuple - sampling rates of the LRADC

• Examples

  rates = LRADC.get_allowable_sample_rates()
  print(rates)
  

set_sample_rate(rate)

Set the current sample rates for the LRADC

• Parameters

  rate - Sample rate, only rates allowable by the LRADC

• Returns

  float - current sampling rate of the LRADC

• Examples

  curr_rate = LRADC.set_sample_rate(125.0)
  

get_sample_rate()

Get the current sample rates for the LRADC

• Parameters

  None

• Returns

  float - current sampling rate of the LRADC

• Examples

  curr_rate = LRADC.get_sample_rate()
  

get_chan0_raw()
