OK you 8266 Basic Gurus, this noob is fuzzy on how I use decimal, Hex, and binary in a variable.
I am trying to do something really simple but I don't have any success.
If I wanted to see if a variable equals a hex value, how do you do it?
Want to see if pressed which is a var equals hex FF;
- none of these work:
if pressed <> HEX (FF) then print something
if pressed <> HEX ((FF)) then print something
if pressed <> 0xFF then print something
likewise, how do you set a vars value? Say I wanted to equate somevar equal to a hex value of A5?
somevar = 0xA5 doesn't work, somevar = HEX(A5) gives me 7FFFFFFFF
Then, how do you equate a variable to a binary number?
Say I wanted to equate or test a variable to 01010101?
Basically I want to equate any numeric variable to a decimal, hex, or binary value, compare a variable against any of these three.
Apologies if this is listed somewhere but I cannot find it in the docs or by perusing other work on this forum.
This is basic and should be easy??

If we knew what we were doing, it wouldn't be called research.
