The Usart_Init function initializes the hardware USART with the specified baud rate.
This function should be called first, before any other USART functions. The only
parameter required by this function is the baud rate. The following example call sets the
baud rate to 9600:
The Usart_Data_Ready function can be called to check whether or not a data byte has
been received by the USART. The function returns a 1 if data has been received and a
0 if no data has been received. The function has no parameters. The following code
checks if a data byte has been received or not:
The Usart_Read function is called to read a data byte from the USART. If data has not been
received, a 0 is returned. Note that reading data from the USART is nonblocking (i.e., thefunction always returnswhether or not theUSART has received a data byte). TheUsart_Read
function should be called after calling the function Usart_Data_Ready to make sure that data
is available at the USART. Usart_Read has no parameters. In the following example,USART
is checked and if a data byte has been received it is copied to variable MyData:
if(Usart_Data_Read( )) MyData = Usart_Read();
The Usart_Write function sends a data byte to the USART, and thus a serial data is sent
out of the USART. The data byte to be sent must be supplied as a parameter to the
function. In the following example, character “A” is sent to the USART:
char Temp = ‘A’;
The following example illustrates how the hardware USART functions can be used in a
