If you were programming using C code, I believe you can hook up any digital sensor to an interrupt port and cause it to trigger an interrupt upon a certain state. However, I don't think this is possible using EasyC, though I could be wrong.

Likewise, if you have access to it (I don't know, haven't used EasyC in a while), putting a command to read the sensor input into the fast loop as opposed to the main one will read as fast as possible with other code executing, which may be fast enough for what you need.

Unfortunately, I don't think either of those options will work using EasyC.
