I am trying to use an LCD display with my MCP23017 IC and Arduino UNO Rev 3 board but I can't find anything about the appropriete connections. The A0 , A1 and A2 pins of the MCP23017 are all connected to ground and reset pin to 5V. I use the LiquidCrystal_I2C.h library with the "Hello World" example but I think also the code needs modifications that I cant find out on my own ... Please help ....
P.S. Since I am not allowed to upload the .ino file I will just copy and paste the code here......
