Hello, I'm trying to get familiar with the creation of own scripts and DLL's to simulate peripherals. If I look to some examples, like for instance the I2CEEPROM example (appnote 153), then the corresponding .ini file (to simulate the I2C behaviour) contains a kind of constants such as I2C_OUT and I2C_IN. If I search for the definition of those constants (where they are defined), then I find them very well hidden inside compiled DLL's (DLPC.DLL and DP51.DLL). But where can I find the exact value of these and other 'hidden' constants? Rgds, Geert
