Protocol

OSC802

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).
