Function Descriptions
This function operates identically to ReadUART.
#define in uart16.h
PIC17C4X, PIC17C756
Reads a string of characters from the software UART.
uart16.h
void getsUART (static char *buffer, static unsigned
char len);
buffer
Pointer to the string of characters read from the software UART.
len
Number of characters read from the software UART. The value
of len can be any 8-bit value, but is restricted to the maximum
size of an array within any bank of RAM.
This function reads a string of characters from the software
UART and places them in buffer. The number of characters read
is given in the variable len.
None
uart16_c.c
char x[10];
getsUART(x,5);
PIC17C4X, PIC17C756
Configures the I/O pins for the software UART.
uart16.h
void OpenUART (void);
None
This function configures the I/O pins used for the software
UART to the correct input or ouput state and logic level. The I/O
pins used for receive data (RXD) and transmit data (TXD) must
be defined in the header file
The definitions that must be made to ensure that the software
UART operates correctly are:
