tsSerialPortSetup

Configure the basic settings for the serial port. Specify the UART hardware to be used and the FIFO memory for input and output.

uint8	u8SerialPort	Serial port (E_AHI_UART_0 or E_AHI_UART_1 should be specified)
uint8*	pu8SerialRxQueueBuffer	Pointer to a FIFO buffer for Rx (UART receive). This buffer shall be statically allocated.
uint16	u16SerialRxQueueSize	Size of the Rx FIFO buffer
uint8*	pu8SerialTxQueueBuffer	Pointer to a FIFO buffer for Tx (UART transmission). This buffer shall be statically allocated.
uint16	u16SerialTxQueueSize	Size of the Tx FIFO buffer
uint32	u32BaudRate	Baud rate (u32BaudRate): Specify 9600 to 115200. Or set the MSB to 0x80XX00YY, where XX is the CBP and YY is the divider setting (see semiconductor peripherals manual)
uint8	u8RX_FIFO_LEVEL	E_AHI_UART_FIFO_LEVEL_1 is specified.

about u32BaudRate

The standard baud rates are 9600, 19200, 38400 and 115200 bps. Other values, out of range values, CBP and divider settings are possible, but are not supported.

If a high baud rate (230400,250000,500000,1000000 [maximum]) is set, processing problems such as dropouts may become more pronounced.

Sample code

tsSerialPortSetup sSerPort;

void vInitSer() {
	/* Create the debug port transmit and receive queues */
	static uint8 au8SerialTxBuffer[256];
	static uint8 au8SerialRxBuffer[256];
​
	/* Initialise the serial port to be used for debug output */
	memset(&sSerPort, 0, sizeof(tsSerialPortSetup));
	sSerPort.pu8SerialRxQueueBuffer = au8SerialRxBuffer;
	sSerPort.pu8SerialTxQueueBuffer = au8SerialTxBuffer;
	sSerPort.u32BaudRate = u32Baud;
	sSerPort.u16AHI_UART_RTS_LOW = 0xffff;
	sSerPort.u16AHI_UART_RTS_HIGH = 0xffff;
	sSerPort.u16SerialRxQueueSize = sizeof(au8SerialRxBuffer);
	sSerPort.u16SerialTxQueueSize = sizeof(au8SerialTxBuffer);
	sSerPort.u8SerialPort = UART_PORT_SLAVE;
	sSerPort.u8RX_FIFO_LEVEL = E_AHI_UART_FIFO_LEVEL_1;
	
	SERIAL_vInit(&sSerPort);
