CAN BUS wiring and ESTOP wiring diagram

Can you provide the canbus wiring and Estop wiring diagrams on the Amiga?
Also if you could share the canbus ID for different parts that would be really helpful.

Hello @Amlan_Balabantaray ,

For the CAN ID’s, you can see the topic & node ID’s in the circuitpython API:

github.com

farm-ng/amiga-dev-kit/blob/main/circuitpy/lib/farm_ng/utils/packet.py

# Python imports
from struct import pack
from struct import unpack

from canio import Message
from supervisor import ticks_ms

from .general import clip
from .general import ticks_diff


DASHBOARD_NODE_ID = 0xE
PENDANT_NODE_ID = 0xF
BRAIN_NODE_ID = 0x1F
SDK_NODE_ID = 0x2A


class ReqRepIds:
    NA = 0
    SUPERVISOR = 1

If you have specific questions / topics / messages you’re looking for, I can help with those.

Regarding the wiring diagram, you can note the following connections inside a representative fork.

1.CAN cable input
2. CAN Hub
3. Terminating Resistor
4. E-stop T connector
5. ASI connection to wheel motor
6. Power from Main Harness (48v) to 24v Buck converter
7. Power from Main Harness (48v) to motor controller
8. 48v → 24v Buck converter
9. Motor Controller

If you are looking for something more specific, @TravisT can help.

Thanks,
Kyle
