Description:
Example(s):
// headers and globals go here…
int main (void)
{
}
unsigned char ReadValue;
// Always call SYS_ConfigureClock first after main() begins
SYS_ConfigureClock(MAX_FCY_RATE);
// initialization code goes here…
UART_Init(115200);
While(1)
{
}
// Echo back any characters received
if(UART_getchar(&ReadValue))
int UART_gets(unsigned char *Data);
int UART_getchar(unsigned char *ch);
UART_putchar(ReadValue);
Data
UART_gets(…) is a copy of the C stdio gets() function. The purpose is to read in a string up until the
carriage return from the UART. Since a user may type in an extremely long string there is no way to know
how big to make the Data buffer so this could become problematic.
This example shows a simple usage scenario.
ch
UART_getchar(…) fills a single character into the passed in destination. If the assignment takes place
the function returns 1, otherwise it returns 0 meaning no data available.
This example shows a simple usage scenario.
A buffer to store data in that includes the carriage return. It must be as large enough to hold the
string. (Potential buffer overrun)
Returns the actual amount of data read including the carriage return.
A pointer to receive a single byte/character.
Returns 1 if there was data assigned to ch, otherwise 0.
// Echo it back
// Configure clock for max
