The program sends a data list to the tool here:
code, ret = arm.getset_tgpio_modbus_data([0x08, 0x10, 0x07, 0x00, 0x00, 0x02, 0x04, 0x0, 0x0, 0x0, 130])
The bytes received on the RS485 lines of the gripper port for that command are 8 16 7 0 0 2 4 0 0 0 130 123 98 in decimal
Could you explain what the list items are and where they are defined?
This is the open gripper command so:
I believe the 0x08 refers to the gripper id of 08 for the biogripper. 10 is a function code The 123 and 98 are likely the CRC check but it doesn’t seem to match any CRC calculators that I can find.
0x10 Hex is 16 Decimal so that is the function code
the 7 0 is the starting register address
0 2 indicates 2 registers
4 0 means that it wants 4 bytes for the data
the 0 0 0 130 dec is 0x0000 0x0082 hex
the 123 98 is the CRC check
The required response is 6 bytes plus the responding CRC check. I haven’t figured out the correct CRC to return so I am still getting an error
