GHI Electronics,LLC Embedded Master User Manual

Hardware and Software Library

● UART0 (COM1)

● UART1 (COM2) This port includes hardware handshaking pins (CTS/RTS)

● UART2 (COM3)

● UART3 (COM4) This port includes IrDA capabilities.

● Also, the user is able to have many more COM ports using USB serial chipsets. For

example, there are many USB <--> Serial cables available and these can be

connected directly to Embedded Master. Check Supported Devices Section.

Example

// create two bytes of data

byte [ ]data = new byte[2];

data[0] = 0x30;

data[1] = 0x55;

SerialPort port = new SerialPort("COM2", 115200, Parity.None, 8, StopBits.One);

port.ReadTimeout = Timeout.Infinite;

port.Open();

// send data

port.Write(data, 0, 2);

Hardware Handshaking on COM2 is supported through C#.

IrDA capabilities is done through direct register access. The user needs to check LPC2478

user manual for details.

Example

Enabling handshaking on UART1 (COM2)

port.Handshake = Handshake.RequestToSend;

port.Open();

Example

Setting Baudrate to 921600
