Figure 9: C100 MSG tool
The numbers in the list below refer to Figure 9:
• 1: Select the blue buttons in the middle to generate messages.
• 2: Fill these fields for CONFIG SET messages.
• 3: The generated message is displayed in the text field at the bottom. It is automatically copied to
the clipboard.
• 4: Use the decode button to parse the contents of a message pasted in the text field (3).
☞ Ensure that the version number of the tool matches the MCU firmware version. Compatibility
between versions is not guaranteed.
5.3.1 Configuration parameters
The following fields are required to generate a CONFIG SET message:
• CAN bitrate: bitrate of the CAN bus
• CAN message ID: ID of the message containing the wanted data
• Data length code: number of bytes in the CAN message
• Cycle time: time between consecutive messages
• Unit: the unit of measurement for the data
• Source: rear-left, rear-right wheel, etc.
• Startbit: index of the LSB of the value field within the CAN message
• Length: the bit-length of the value field
• Endianness: Big-endian (Motorola) or Little-endian (Intel)
• Sign: value is signed or unsigned
• Factor: scaling factor representing the value of one bit in the selected unit
• Offset: positive offset which shifts the zero point of the raw value
• Min/Forward:
o Wheel tick and speed – sets the minimum value. Values smaller than this are discarded.
o Direction – represents the value indicating forward movement
• Max/Backward:
o Wheel tick and speed – sets the maximum value. Values greater than this are discarded.
o Direction – represents the value indicating backward movement
