EnviroPlus-FeatherWing TODO

Things_to_do.txt

Idea about the example
----------------------

simpletest example could be only present in each individual library.
More complex example that use the plotter could be in the main library for EnviroPlus-FeatherWing.

Move from gas to MICS6814
-------------------------

Replace gas.py from library with the new library https://github.com/pimoroni/Pimoroni_CircuitPython_MICS6814

0) (optional) add MICS6814 to the community bundle
1) remove library/pimoroni_envoriwing/gas.py
2) create a new link to Pimoroni_CircuitPython_MICS6814
3) in folder exemples, adapt the following 4:
  gas_sensor.py:from pimoroni_envirowing import gas
  plotter_gas.py:from pimoroni_envirowing import gas
  plotters_combined.py:from pimoroni_envirowing import gas, screen
  test_all.py:from pimoroni_envirowing import gas

Move to the new LTR559
----------------------

Replace https://github.com/pimoroni/ltr559-python/ by https://github.com/pimoroni/Pimoroni_CircuitPython_LTR559/

1) remove the link submodules/pms5003-circuitpython
2) create a new link to Pimoroni_CircuitPython_MICS6814
3) in folder exemples, adapt the following:
  plotter_light_and_sound.py:from pimoroni_circuitpython_ltr559 import Pimoroni_LTR559
  proximity_and_light.py:from pimoroni_circuitpython_ltr559 import Pimoroni_LTR559
  plotters_combined.py:from pimoroni_ltr559 import LTR559
  test_all.py:from pimoroni_ltr559 import LTR559
4) This could be the last user of the i2cdevice-python submodule, so it might be possible to unlink

Move from pms5003 to PM25
-------------------------

Stop using pimoroni_pms5003 and start using adafruit_pm25

1) Verify if some improvement from pms5003 can be applied to pm25 and make needed PR
2) Replace the use of https://github.com/pimoroni/pms5003-circuitpython/ by the use of https://github.com/adafruit/Adafruit_CircuitPython_PM25
3) in folder exemples, adapt the following 4:
  particulate_sensor.py:from pimoroni_pms5003 import PMS5003
  plotter_particulate.py:from pimoroni_pms5003 import PMS5003
  plotters_combined.py:from pimoroni_pms5003 import PMS5003
  test_all.py:from pimoroni_pms5003 import PMS5003

Adapt screen to not use physical_feather_pins
---------------------------------------------

The screen library /lib/pimoroni_envirowing/screen still use pimoroni_physical_feather_pins to find the command, chip_select and reset pin.

__init__.py:    import pimoroni_physical_feather_pins
__init__.py:        display_bus = displayio.FourWire(spi, command=pimoroni_physical_feather_pins.pin19(), chip_select=pimoroni_physical_feather_pins.pin20(), reset=pimoroni_physical_feather_pins.pin21())
__init__.py:        display_bus = displayio.FourWire(spi, command=pimoroni_physical_feather_pins.pin19(), chip_select=pimoroni_physical_feather_pins.pin20())

With some default parameter, it should be possible not to have to modify the current example and at least work on M4.

Chase any left use of physical_feather_pins
-------------------------------------------

Not sure exaclty what other usage are left.

Detailed task for pimoroni/EnviroPlus-FeatherWing#5

I've PR'd MICS6814 into the community bundle, which is at least a step in the right direction. Thanks for keeping at this!
