EXAMPLE:
The following C program shows how the SCI functions are used.
This program runs the following sequence for an SCI without extended baudrate prescaler for
polling or interrupt driven mode:
– transmits a single byte passed by the user
– transmits the 20 bytes of data at the baudrate 9600
– receives 20 bytes of data at a baud rate of 9600.
Note: You must define the communication mode and cpu speed (Fcpu) in the ST7lib_config.h
file.
You can select any of the communication speeds from the following list :
SCI_POLLING_TX
SCI_POLLING_RX
SCI_ITDRV_WITHOUTBUF_TX
SCI_ITDRV_WITHOUTBUF_RX
/* You can use a timeout function to handle the fault in which the control will get stuck in side
a loop.This function should have the Boolean return, i.e it should return TRUE if the expected
wait Time is not elapsed and FALSE if it is elapsed.*/
