Now, I have three .c files (main.c, fifo.c, stdio_through_usart.c). In all of them is included fifo.h.
fifo.h contains:
#ifndef FIFO_H
#define FIFO_H
#define RXSIZE 1024
#define TXSIZE 512
uint8_t RxBuffer[RXSIZE];
uint8_t TxBuffer[TXSIZE];
typedef
struct
{
char
* buf;
int
head;
int
tail;
int
size;
} fifo_t;
fifo_t RxFifo[1];
fifo_t TxFifo[1];
void
fifo_init(fifo_t * f,
char
* buf,
int
size);
int
fifo_read(fifo_t * f,
void
* buf,
int
nbytes);
int
fifo_write(fifo_t * f,
const
void
* buf,
int
nbytes);
#endif /* FIFO_H */
But now there is new errors. Is this double inclusion? I have defined these arrays just once.
Error: L6200E: Symbol RxBuffer multiply defined (by stdio_through_usart.o and main.o).
