# Super Simple UART config for ATmega
|
|
|
|
lets you use normal `printf()` in your code.
|
|
|
|
### Adjustments to make
|
|
the default configuration works on an atmega328p with 38400 baud. Any other setup might require one of the following changes.
|
|
|
|
#### Set baudrate in 'uart.h'
|
|
line 6:
|
|
`#define BAUD 38400`
|
|
|
|
#### Select which UART to use
|
|
If your controller has more than one UART hardware and you want to use a different than UART0,
|
|
change the register defines in the following way:
|
|
|
|
##### Example: UART0 -> UART3
|
|
from `#define UART_BAUD_REGH UBRR0H` to `#define UART_BAUD_REGH UBRR3H`</br>
|
|
and</br>
|
|
from `#define UART_UCSZ0_BM UCSZ00` to `#define UART_UCSZ0_BM UCSZ30`
