Hi, I need proposal for connected LPC2103 to PIC16f628, I made led display who work with pic16f628 like master IC, but No. of characters is limited, I need to put large No. of character on SD card and via LPC2103 sending massage to master PIC, regards
What interfaces does your PIC subsystem have available?
UART? I2C? SPI?
etc...?
UART, regards
You have only one interface to use; so there is nothing to choose - just use it!
