> Hi all!
> I'd like to use my ATmega8 as interface between USART and i2c (and for some
> other things too, but it's not important for my problem). When i write
> support for I2C in my code (i'm using Procyon AVRLib) everything is OK, but
> when i try to add support for UART, compiler (avr-gcc) says me Error.
> Here is my code:
> Code:
> #include "i2c.c" // i2c library
> #include "uart.h" // uart library
> // headers
> /*
> Here is defined some constants like i2c addresses
> */
> void inicializaceI2C() { // setting I2C
> i2cInit();
> i2cSetLocalDeviceAddr(0xA8, TRUE);
> }
> void inicializaceUart() { // setting UART
> uartInit();
> uartSetBaudRate(9600);
> }
> int main() {
> inicializaceI2C();
> inicializaceUart();
> while(1) { }
> return 0;

> When i try to build it, AVRstudio says me, uart.h is in conflict with
> uart2.h (included by i2c.c). When I try compile this code without
> Code:
> #include "uart.h" // uart library
> avr studio says me:
> Code:
> error: too few arguments in function uartSetBaudRate
> When I try modify my code to using UART0, avr studio says me, uart0
> nonexists.
> Have you any idea how to use i2c and uart together on ATMega8 or should I
