sub function UARTx_Data_Ready() as byte

Function returns 

1

if data is ready or

0

if there is no data.

The function tests if data in receive buffer is ready for reading.

MCU with the UART module.

The UART module must be initialized before using this routine. See the
UARTx_Init routine.

dim receive as byte
...

' read data if ready
if (UART1_Data_Ready() = 1) then

receive = UART1_Read()

sub function UARTx_Read() as byte

Received byte.

The function receives a byte via UART. Use the UARTx_Data_Ready function to
test if data is ready first.

MCU with the UART module.

The UART module must be initialized before using this routine. See UARTx_Init
routine.

dim receive as byte
...
' read data if ready
if (UART1_Data_Ready() = 1) then

receive = UART1_Read()
