Converting from hexadecimal to binary in Igor 8

The sscanf operation will do it. Here is a simple example:

Function test()
    Variable var
    sscanf "0xff34", "%x", var
    print var
end

•test()
  65332

The receiving variable must be a variable, so if you want the result in a wave you must assign it after the call to sscanf.

I suggest you execute the following command to bring up the related help topic:

You can do what john suggested to get the hex value into a numeric variable. Then you can test each of the bits to get the state of the channel.

If you really need this in a binary representation (eg. "01011010101010") then you can use printf with the %b conversion character.

Thank you, these comments were very helpful!

I ended up using aclight's second suggestion, which was using sscanf suggested by John and then using sprintf with the %b character:

sscanf hex_value, "%x", int_value
sprintf binary_value, "%b\r", int_value

Thanks again for your help!
