|
******************************************
|
| 28 |
|
|
The uTosNet_spi Digi application is meant for use with the Ethernet/SPI
|
| 29 |
|
|
version of uTosNet. It provides the server application that should run
|
| 30 |
|
|
on the Digi Connect ME 9210 microcontroller module, in order for it to
|
| 31 |
|
|
work with the uTosNet_spi FPGA module and PC application.

|
* Building
|
| 35 |
|
|
******************************************
|
| 36 |
|
|
Use the Digi IDE to create a new project, and use the accompanying
|
| 37 |
|
|
root.cxx file as the main file. Then build and download it according
|
| 38 |
|
|
to standard Digi procedures.

|
* Usage
|
| 42 |
|
|
******************************************
|
| 43 |
|
|
The server application listens on port 50000, and uses a binary protocol.
|
| 44 |
|
|
It accepts the following kinds of packets:
|
| 45 |
|
|
(for all packets bit 31 is MSB, all unspecified bits should be '0')
|
| 46 |
|
|
|
| 47 |
|
|
|
| 48 |
|
|
- Read request (32 bits):
|
| 49 |
|
|
- Bit 29: Set to '1'
|
| 50 |
|
|
- Bit 25-16: Set to read address
|
| 51 |
|
|
- Set all others to '0'
|
| 52 |
|
|
|
| 53 |
|
|
Response (32 bits):
|
| 54 |
|
|
- Bit 31-0: Contains read data
|
| 55 |
|
|
|
| 56 |
|
|
|
| 57 |
|
|
- Write request (2x32 bits):
|
| 58 |
|
|
First 32 bits:
|
| 59 |
|
|
- Bit 11: Set to '1'
|
| 60 |
|
|
- Bit 9-0: Set to write address
|
| 61 |
|
|
Second 32 bits:
|
| 62 |
|
|
- Bit 31-0: Set to write data
|
| 63 |
|
|
|
| 64 |
|
|
Response: None
|
| 65 |
|
|
|
| 66 |
|
|
|
| 67 |
|
|
- Combined read/write (2x32 bits)
|
| 68 |
|
|
First 32 bits:
|
| 69 |
|
|
- Bit 29: Set to '1'
|
| 70 |
|
|
- Bit 25-16: Set to read address
|
| 71 |
|
|
- Bit 11: Set to '1'
|
| 72 |
|
|
- Bit 9-0: Set to write address
|
| 73 |
|
|
Second 32 bits:
|
| 74 |
|
|
- Bit 31-0: Set to write data
|
| 75 |
|
|
|
