sub procedure UARTx_Write(dim TxData as byte)

Nothing.

The function transmits a byte via the UART module.

Parameters : 

- 

TxData:

data to be sent 

MCU with the UART module.

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

dim data_ as byte
...

data_ = 0x1E
UART1_Write(data_)

sub procedure UARTx_Write_Text(dim byref uart_text as
string[255])

Nothing.

Sends text (parameter uart_text) via UART. Text should be zero terminated.

UART HW module must be initialized and communication established before
using this function. See UARTx_Init.

Read text until the sequence “OK” is received, and send back what’s been received:

UART1_Init(4800)                           ' initialize UART

module
Delay_ms(100)

while TRUE

if (UART1_Data_Ready() = 1)           ' if data is received   

UART1_Read_Text(output, 'delim', 10)  ' reads text until

'delim' is found

UART1_Write_Text(output)              ' sends back text
