Function Documentation

uint8_t getUartNum ( LPC_UART_TypeDef *  UARTx  ) 

Get UART number due to UART peripheral pointer.

Parameters:
[in] UARTx UART pointer
Returns:
UART number

Definition at line 94 of file lpc17xx_uart.c.

void UART_GenIntHandler ( LPC_UART_TypeDef *  UARTx  ) 

General UART interrupt handler and router.

Parameters:
[in] UARTx Selected UART peripheral, should be UART0..3
Returns:
None
Note:
  • Handles transmit, receive, and status interrupts for the UART. Based on the interrupt status, routes the interrupt to the respective call-back to be handled by the user application using this driver.
  • If callback is not installed, corresponding interrupt will be disabled
  • All these interrupt source below will be checked:
    • Transmit Holding Register Empty.
      • Received Data Available and Character Time Out.
      • Receive Line Status (not implemented)
      • End of auto-baud interrupt (not implemented)
      • Auto-Baudrate Time-Out interrupt (not implemented)
      • Modem Status interrupt (UART0 Modem functionality)
      • CTS signal transition interrupt (UART0 Modem functionality)

Status uart_set_divisors ( LPC_UART_TypeDef *  UARTx,
uint32_t  baudrate 
)

Determines best dividers to get a target clock rate.

Parameters:
[in] UARTx Pointer to selected UART peripheral, should be UART0, UART1, UART2 or UART3.
[in] baudrate Desired UART baud rate.
Returns:
Error status.
