2 // config for uart module
\r
5 * This is the configuration file for the uart module.
\r
6 * This module provides :
\r
7 * - Tx and Rx with fifo
\r
8 * - two modes : the first one tries to be faster ; when you try to
\r
9 * send data and the fifo is full, the byte is dropped. The second
\r
10 * one (with UART1_DONT_LOOSE_DATA defined) can be slower ; when the
\r
11 * fifo is full, the writing of a data blocks in the interrupt.
\r
12 * - Speed selection (for the moment the module don't use the UBRRxH
\r
13 * register so the speed cannot be too low. (min is 4800 at 16 Mhz)
\r
14 * - Parity selection (if the uC support it)
\r
15 * - 5 to 9 data bits (if the uC support it). Warning : when you use
\r
16 * 9 bits, the prototypes of the functions change (uint8_t become uint16_t).
\r
17 * - 1 or 2 stop bits (if the uC support it).
\r
18 * - 2 UARTs (if the uC support it).
\r
22 * Number of bits in frame for tx and rx are the same
\r
24 * It doesn't support some USART capabilities :
\r
25 * - Synchronous mode
\r
26 * - Multiprocessor communication
