Description:
Example(s):
unsigned char ReadBuf[5];
// Read the data in
int NumberRead = UART_read(ReadBuf,5);
// Display how much data we read
UART_printf(“We read in %d bytes\r\n”,NumberRead);
_____________________________________________________________________________________________
// Initialize the uart driver at 115200 baud rate
UART_Init(115200);
// Send the classic example “Hello World”
UART_printf(“Hello World!\r\n”);
void UART_puts( const char *buff);
int UART_read( unsigned char *Data, int Length);
buff
UART_puts(…) sends a null terminated string out of the UART. If you are sending a constant string out of
the UART, UART_puts(..) is less resource and computational demanding than the alternative
UART_printf(...).
This example shows a simple usage scenario.
Data
Length
Returns the actual amount of data read. This could be less than Length depending on the available data.
UART_read(…) attempts to read from the UART driver’s internal circular read buffer and stores the data
into the passed in Data buffer. This will read Length bytes if there is enough data available, otherwise it
returns the number of bytes actually read.
This example shows a simple usage scenario.
A null terminated string.
None.
A buffer to store data in. It must be as large or larger than Length.
The amount of data to read.
