Communication Protocols

4.1 CAN-FD Communication

CAN-FD communication parameters: arbitration field baud rate 1M (80% sampling point), data field baud rate 5M (75% sampling point). This device supports CAN‑FD frame format only. For classic CAN 2.0 frames, the device will: • not parse the data • not send any acknowledgment • not generate error frames

The following is the communication frame layout in the CANFD data field:

• Node ID: 0~0x7FF, standard frame. Default ID is 0x09. When the node ID is unknown, you can use paging address 0x7FF to query the node ID. The node will still reply according to its own ID after receiving this ID data.

• CMD: Control command, which will occupy the first byte in the data field and its specific definition is detailed in Chapter 4.3.

• Data segment: Data corresponding to the control command and its specific definition is detailed in Chapter 4.3 Upstream/Downstream Data Definitions; all data is arranged in little-endian format.

Command examples (hex format):

A. Enable command: 0x09 0x02 0x01 0x01

B. Disable command: 0x09 0x02 0x01 0x00

C. Set Motor 1 to position 2000: 0x09 0x04 0x06 0x01 0x00 0x7D

D. Set all motors to position 2000:

0x09 0x18 0x08 00 7D 00 7D 00 7D 00 7D 00 7D 00 7D 00 7D 00 7D 00 7D 00 7D 00 7D

4.2 USB/Serial Communication

Serial communication parameter settings:

• Baud rate: 460800

• Total bytes: 8

• Check bit: None

• Stop bit: 1

When using USB connection, the driver board will virtualize a serial port; the baud rate can be freely set while other parameters are kept identical.

• Frame header: 0xAAEE,little-endian format

• ID: Device Node ID, 0~0x7FF. Default ID is 0x01. When the node ID is unknown, you can use paging address 0x7FF to query the node ID. The node will still reply according to its own ID after receiving this ID data, little-endian format

• Data length: Byte length of the data segment

• Data segment: the length is 1-64, the first byte is the control command, followed by corresponding data, identical with the data field in CAN-FD, all data is arranged in little-endian format.

• crc: Data verification. The verification range ranges from the frame header to the data segment. For its calculation method, please refer to the crcl6 function in the following file. The value 0x5555 is reserved as a debug-specific crc, which can pass the verification directly.Little-endian format.

• crc calculation details:

• Initial value: 0x0000

• Polynomial: 0x1021

• XOR output: 0x0000

• Data reflection: none, uses MSB‑first bit order

• Command examples (hex format):

• Enable command: 0xEE 0xAA 0x01 0x00 0x02 0x01 0x01 0x60 0xAA

• Disable command: 0xEE 0xAA 0x01 0x00 0x02 0x01 0x00 0x41 0xBA

For each fingertip, the pressure measurement point is a composite of three individual points, the palm contains nine points, and the back of hand contains five points.

5.7 Upgrade Panel

In the Upgrade Panel, click the “current version” button to view the current firmware version and other related information of the device.

To perform a firmware upgrade, click “Start Upgrade,” then select the prepared firmware file (*.bin). OmniHand will begin updating its firmware.

Before starting the upgrade, ensure that the device is properly connected. Once the upgrade begins, please wait patiently for the process to complete. Progress and status messages will be printed in the log. By checking the log, you can confirm whether the upgrade is successful. A successful upgrade will display messages such as “OTA completed normally” and “Reboot is normal.”

If “Upgrade Failed” appears, try performing the upgrade again by clicking “Start Upgrade” and repeating the operation. If the upgrade still fails, review the log messages. If the log indicates a connection failure, you may need to update the MCU firmware using an ST‑Link programmer before retrying.

This manual is based on OmniHand, Hardware Version 3.0.0, Firmware Version 1.2.12, and Host Software Version 2.6.33.
