It is the exact same problem that I am having.
What version of the Phidget21 lib do you have loaded? (I have Build 2.1.5)
And what is your Phidget TextLCD version Number? (mine is a Version 123)
Alan indicates he is still using Phidget21v Lib 2.1.4 to test the FS2Phidgets
I have found out that my TextLCD unit will not even load up in FS2Phidget with the Phidget21 lib 2.1.4 installed.
What is your PC system configuration?
