4. CAN protocol
This protocol is specific and designed by MSS.
The product send, at a period TFRAME_CAN (can be setup in EEPROM by user with a minimum of 1ms), the selected
data, after receivingtherightrequest"controllertoslave".
Rate can be configured from 125kbauds to 1Mbauds, by a register in EEPROM.
Protocol details:
The product send data or stop sending data after receiving the following request:
Controller to slave request:
Identifier / (4 bytes)
0x1FFFD8B0
SEL_TX
0x00
0x01
0x02
0x03
0x04
0x05
0x06
0x07
Frame from IMU to controller:
3 types of data frame are sent by product, identified by three different identifiers.
If more than one data frame has to be sent, then these data are sent with the following priority DATA1, DATA2 and then
DATA3 (see scheme below):
TFRAME_CAN
DATA1
DATA2
Data are transmitted 'MSB first'.
