mikoBasic PRO for dsPIC30/33 and PIC24

MikroElektronika

Returns

Nothing.

Requires

Routine requires the UART module.

Example

‘ dsPIC30 family example

‘ Initialize hardware UART1 module and establish communication at 2400 bps,

8-bit data, even parity and 2 STOP bits

UART1_Init_Advanced(2400, 2, 1)

‘ dsPIC33 and PIC24 family example

‘ Initialize hardware UART2 module and establish communication at 2400 bps,

8-bit data, even parity, 2 STOP bits and high speed baud rate calculations

UART2_Init_Advanced(2400, 2, 1, 1)

Notes

Refer to the device data sheet for baud rates allowed for specific Fosc.

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.

Switching between the UART modules in the UART library is done by the UART_Set_Active function

(UART modules have to be previously initialized).

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

before utilizing this library.

UARTx_Data_Ready

Prototype

sub function UARTx_Data_Ready() as word

Description The function tests if data in receive buffer is ready for reading.
Parameters None.
Returns

if data is ready for reading

if there is no data in the receive register

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 receive as word

...

‘ read data if ready

if (UART1_Data_Ready() = 1) then
