Macro reference

Fc9-comp-macro.png InitialiseSim
Resets and initialises the Internet E-Block. It sets up the gateway address, subnet mask, device IP address and device MAC address as defined in the properties of the Flowcode component. This macro must be called before any other TCP_IP component macros  
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png TxSendMyIP
This macro fills the specified channel's transmit buffer with 4 bytes of data representing this Internet E-Block's IP address as specified in the component's property page. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png TxSendString_Sim
This macro fills the specified channel's transmit buffer with data. It can fill the buffer with a string of information. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-string-icon.png - STRING Data
Data byte to append to Tx buffer. 
Fc9-u8-icon.png - BYTE Length
 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png RxReadHeader_Sim
A call to this macro will return a byte of data in the reception buffer of the specified channel. It will also internally increment a pointer to that data so that the next call to 'Rx_readbyte' (or any other read function) will read the next byte  
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-u8-icon.png - BYTE Idx
 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png RxMatch_6_Bytes_Sim
This macro returns a non-zero value when the next 6 bytes of data in the specified channel's reception buffer are the same as those passed as parameters. There are similar functions that check for 2 bytes and 4 bytes. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-u8-icon.png - BYTE Byte1
Specifies the value of the first byte 
Fc9-u8-icon.png - BYTE Byte2
Specifies the value of the second byte 
Fc9-u8-icon.png - BYTE Byte3
Specifies the value of the third byte 
Fc9-u8-icon.png - BYTE Byte4
Specifies the value of the fourth byte 
Fc9-u8-icon.png - BYTE Byte5
Specifies the value of the fifth byte 
Fc9-u8-icon.png - BYTE Byte6
Specifies the value of the sixth byte 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png RxMatchMyIP
This macro returns a non-zero value when the next 4 bytes of data in the specified channel's reception buffer are the same as the Internet E-block's IP address. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png TxStart_Sim
This macro indicates the start of data transmission for the specified buffer. In TCP mode, data transmission can only begin once the socket has become established. In other modes, data transmission can occur as soon as the socket has been opened. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png TCPClose_Sim
When an established TCP connection has finished transmission of data, either the local application (i.e. your code) or the remote application (i.e. the application at the other end of the connection) can initiate closure of the socket. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png RxDataAvailable_Sim
This macro is used to check whether or not data has been received by the Internet E-Block. A return value of zero indicated that no data has been received. A positive return value indicates that data is available. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png RxMatch_4_Bytes
This macro returns a non-zero value when the next 4 bytes of data in the specified channel's reception buffer are the same as those passed as parameters. There are similar functions that check for 2 bytes and 6 bytes. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-u8-icon.png - BYTE Byte1
Specifies the value of the first byte 
Fc9-u8-icon.png - BYTE Byte2
Specifies the value of the second byte 
Fc9-u8-icon.png - BYTE Byte3
Specifies the value of the third byte 
Fc9-u8-icon.png - BYTE Byte4
Specifies the value of the fourth byte 
Fc9-u8-icon.png - BYTE Return


Fc9-comp-macro.png SetMyIP
This macro sets up the Internet E-Block's own IP address. In most circumstances, this macro will not be required as the IP address setting in the component property page will remain constant throughout your application. 
Fc9-u8-icon.png - BYTE IP0
First Byte of IP address 
Fc9-u8-icon.png - BYTE IP1
Second Byte of IP address 
Fc9-u8-icon.png - BYTE IP2
Third Byte of IP address 
Fc9-u8-icon.png - BYTE IP3
Fourth Byte of IP address 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png TxSendString
This macro fills the specified channel's transmit buffer with data. It can fill the buffer with a string of information. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-string-icon.png - STRING Data
Data byte to append to Tx buffer. 
Fc9-u8-icon.png - BYTE Length
 
Fc9-void-icon.png - VOID Return


Fc9-comp-macro.png SetDestination_Sim
This is used in IP and UDP modes to set the destination of the intended data transfer. The destination IP address needs to be set for both IP and UDP modes. 
Fc9-u8-icon.png - BYTE Channel
Specifies the communications channel 0-3 
Fc9-u8-icon.png - BYTE Dst_IP0
Specifies the first byte of an IP address 
Fc9-u8-icon.png - BYTE Dst_IP1

On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
