Hello Everyone,
I have this questions particularly from someone that already use the chip MCP23S17 and how to program it with Mikro C PRO using Port_Expander Library with PIC18F4550. I see some sample codes with circuit diagram in Mikro C PRO and I manage to test it and it works, my Question is how about using 8 MCP23S17 and TRISing independent GPIO bit? How to connect it in PIC18F4550 in SPI? I know some basics about SPI and I read some of info. about Hardware Address of MCP23S17 with the help of Mikro C Pro. Feel free to ask question if you don't understand my question. Thank you.
