Commands sent via Control Transfer to EP0. Samples buffer available on Bulk EP. List of commands (provisional):
| Request Type | Request | Value | Index | Data | Description |
|---|---|---|---|---|---|
| 0x80 | 0x33 | 0x00 | 0x00 | 1 byte | Start acquisition. |
| 0x80 | 0x50 | 0x00 | 0x00 | 1 byte | Check if acquisition buffer is ready. Write 0x21 in the data byte if ready. |
| 0x80 | 0x94 | value | 0x00 | 1 byte | Set sampling rate with value[0-3] and AC/DC for Channel 1 with value[4].
Rate values: 80MSa/s (B0000), 10MSa/s (B1000), 625KSa/s (B1100) value[4] = 1 -> DC coupling, value[4] = 0 -> AC coupling |
| 0x80 | 0x22 0x23 0x24 | value | 0x00 | 1 byte | Set Channel 1 and Channel 2 voltage. Set AC/DC for Channel 2. |
| 0x80 | 0xE7 | value | 0x00 | 1 byte | Enable (value=1) or disable (value=0) hardware trigger on Channel 1. |
| 0x80 | 0xC5 | value | 0x00 | 1 byte | Set trigger slope up (value=1) or down (value=0). |
| 0x80 | 0x16 | value | 0x00 | 1 byte | Set trigger level (value=0-255). |
