Make use of type dispatch

[s-celles]

Hello,

Looking at SenseHat.jl code, I noticed (for example)

SenseHat.jl/src/sensors.jl

Line 36 in a30a6cd

humidity() = HTS221_humidity()

Maybe you should consider making use of type dispatch

abstract type AbstractSensor end
struct HTS221 <: AbstractSensor
end

humidity()    = humidity(HTS221()) 

Kind regards

PS : I didn't test code

led_clear could simply be named clear

SenseHat.jl/src/led.jl

Line 138 in a30a6cd

function led_clear()

sense = SenseHat()
clear(sense.led)

Maybe you should also make use of setproperty! / getproperty

Array(sense.led)  # or sh.led.array ?
sense.led.array = new_array  # setproperty!

sense.led.gamma = new_gamma
gamma = sh.led.gamma
