With Proteus 8.8 and later it insert automatically the library downloaded from SamacSys Search Engine (by downloading the ECAD icon). Than googling around I found this Libray Loader. This because the Proteus device is not the same as the one I have. Now, inside Proteus, I found different Alphanumeric LCD (16x2, 20x4 ecc.) and I made the circuit, wrote the code and the simulation goes fine.īut if I write my PIC (with MPLAB and PICKIT3 Kit) and build the real circuit the LCD remain empty, nothing works. Now I'm trying to interfacing a particular Hitachi HD44780 LCD Display (drived with PCF8574 controller) via I2C with my PIC16F1829 microcontroller. I'm new here and I'm using a Proteus 8.6 Professional (provided from my University) on a old 32bit PC and it works pretty well.
