TCP/IP
The TCP/IP communication adaptor can be used to connect with a target in case the target is present at a different location and cannot be physically connected the the PC that is running SigmaStudio+. SigmaStudio+ communicates with a server connected to the target using TCP/IP. The TCP/IP is present under the Communication Adaptors tree within the toolbox.
Settings
Following options are available on the settings window, which can be launched by double clicking on the TCP/IP shape in canvas
- IP Address - IP address on which the server connected to target is listening
- Port - Port number on which the server connected to target is listening
- Close Connection - Close the connection
- Open Connection - Open Connection
- Register ASAP Connection - Establish connection without performing the background operations
- Max Buffer Size - Maximum data buffer size
Once the server is connected, SigmaStudio is free to send and receive data to and from the server.
Write Data Format
SigmaStudio+ sends the code and parameter information to the server connected to target in the following format:
| Field | Description |
|---|---|
| ————————————-- | ——————————————————— |
| Control | This is the control bit that is used to indicate that it is a write packet. Its value is 0x09 |
| Block / safeload write bit | This field indicates whether the write packet is a block write or a safeload write |
| Channel number | This indicates the channel number |
| Total length | This indicates the total length of the write packet. It is 4 bytes long |
| Chip address | This is the address of the chip to which the data has to be written |
| Data Length | This is the length of the data. This is 4 bytes long |
| Address | This is the address of the module whose data is being written to the DSP. This is 2 bytes long |
| Data | This is the data to be written |
Read Request format
In order to achieve readback, SigmaStudio+ send a read request. The read request format is as shown
| Field | Description |
|---|---|
| ————————————-- | ——————————————————— |
| Control | This is the control bit that is used to indicate that it is a read packet. Its value is 0x0A |
| Total length | This indicates the total length of the read packet. It is 4 bytes long |
| Chip address | This is the address of the chip for which the data has to be read from |
| Data Length | This is the length of the data to read. This is 4 bytes long |
| Address | This is the address of the module whose data is being read from the DSP. This is 2 bytes long |
| Reserved | There are two fields reserved for future use. |
Read Response Format
The server connected to target must respond to the read request with a read response in the following format:
| Field | Description |
|---|---|
| ———————————- | ——————————————————— |
| Control | This is the control bit that is used to indicate that it is a read response packet. Its value is 0x0B |
| Total length | This indicates the total length of the read response packet. It is 4 bytes long |
| Chip address | This is the address of the chip to which the data has been read from |
| Data Length | This is the length of the data. This is 4 bytes long |
| Address | This is the address of the module whose data has been read from the DSP. This is 2 bytes long |
| Success / Failure | This byte indicates whether the read operation was a success or failure. It should be populated with a 0 for success and 1 for failure |
| Reserved | This field is reserved for future use |
| Data | This is the data read from the address |
