piGlow on ESP8266-01
Posted: Sat Dec 19, 2015 8:18 amI Apologise in advance, the code will not be correct or complete as I'm learning. This is just an online placeholder while I work out how to get the i2c PiGlow working.
Question 1, Do I have to use "Let Address=" or can I use "Let i2c_addr" ?
Question 2, Is "Let" lower or upper case? - finding it hard to read the examples.
updated but not sure on the values.....
