+####Read an HX711 load cell ADC.
+Note: currently only chanel A with gain 128 is supported.
+The HX711 is an inexpensive 24bit ADC with programmable 128x, 64x, and 32x gain.  
+```lua
+	-- Initialize the hx711 with clk and data pin assignments
+	hx711.init(5,6)
+	-- Read ch A with 128 gain.
+	raw_data = hx711.read()
+```
