Toolset assemnbled ala Lynch tutorial. I am starting to add UART code to blinky.

I have added a uart.c and uart.h. uart.c added to Makefile.

In uart.h I have declared: void uart0Putch(unsigned char byte_out);

In main.c I call: uart0Putch(0xAA);

This results in a “undefined reference” error at this line.

I add a void to get: void uart0Putch(0xAA);

and I get the errors: “parse error before numeric constant” and conflicting types for ’ uart0Putch’

there is also an error in uart.h at the function declaration: ‘previous declaration of uart0Putch was here’

What gives?

Thanks

Rich
