UARTx_Write

Prototype

sub procedure UARTx_Write(dim data_ as word)

Description The function transmits a byte via the UART module.
Parameters -

data_

: data to be sent

Returns

Nothing.

Requires

Routine requires at least one UART module.

Used UART module must be initialized before using this routine. See UARTx_Init and UARTx_Init_

Advanced routines.

Example

dim data_ as byte

...

data_ = 0x1E

UART1_Write(data_)

Notes

UART library routines require you to specify the module you want to use. To select the desired UART

module, simply change the letter

x in the routine prototype for a number from 1 to 4.

Number of UART modules per MCU differs from chip to chip. Please, read the appropriate datasheet

before utilizing this library.

UARTx_Write_Text

Prototype

sub procedure UARTx_Write_Text(dim byref uart_text as string[20])

Description Sends text via UART. Text should be zero terminated.
Parameters -

UART_text

: text to be sent

Returns

Nothing.

Requires

Routine requires at least one UART module.

Used UART module must be initialized before using this routine. See UARTx_Init and UARTx_Init_

Advanced routines.

Example

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, ‘OK’, 10) ‘ reads text until ‘OK’ is found

UART1_Write_Text(output) ‘ sends back text

end if

wend.
