Custom Temperature Sensors #105

Open mloit opened 6 years ago

mloit commented 6 years ago

Currently adding a custom temperature sensor is a real pain. It would be great if TemperatureSensorConfigs.py could be relocated to the redeem working directory /etc/redeem. Or even better, some mechanism added into the config file to be able to define the sensor.

How much customization do you mean? Adding a new thermistor table, direct connect to the BBB's adc, external ADC over i2c, something else?

Just the ability to add new entries to the tables that already exist in an easier way. Could be as simple as relocating TemperatureSensorConfigs.py to a more accessible location than /usr/local/lib/python2.7/dist-packages/Redeem-[VERSION]-py2.7-linux-armv7l.egg/redeem perhaps placing it in /etc/redeem? Or my preference would be to have it on the config file in the [Heaters] section, providing a mechanism to add the parameters for the sensor, instead of directly editing the table... perhaps something like: 

sensor_E = CUSTOM(NTC, "Semitec-104NT4", 4700, 0.797110609710217e-3, 2.13433144381270e-4, 0.65338987554e-7)

sensor_E = CUSTOM(PTC, "E3D-PT100-AMPLIFIER", 4700, 100, 0.0039083, -5.77e-07)

sensor_E = CUSTOM(OTHER, "Thermocouple", 0.005)
