6.2 FoxPi_write#

本章節介紹如何透過 FoxtronPi 控制車輛。

當需進行 FoxtronPi 訊號控制時，必須先將 Ctrl_Enable_Switch 旗標設定為 1。該旗標作為啟用控制功能的前置條件，若未正確設定，所有控制操作將被系統拒絕執行。

建立 FoxtronPi DID 讀取器。

class FoxPiWriteDID(client):

client: (udsoncan.client.Client) 已開啟的 UDS 客戶端，用於發送 WriteDataByIdentifier 等請求。
Raises: 任何由 client.write_data_by_identifier() 拋出的通訊錯誤(如逾時、負回應)。

6.2.1 車輛動態操作流程 (FoxPi_Driving_Ctrl)#

6.2.2 燈光控制操作流程 (FoxPi_Lamp_Ctrl)#

6.2.3 FoxPi_Ctrl_Enable_Switch()#

Parameters: user_input[1]
Return type: Bytes (實際寫入的封包內容)，Error 時回傳 None。

Example Code/Output

from doipclient import DoIPClient
from doipclient.connectors import DoIPClientUDSConnector
from udsoncan.client import Client
from common import get_uds_client
from client_config import DOIP_SERVER_IP, DoIP_LOGICAL_ADDRESS
from FoxPi_write import FoxPiWriteDID

doip_client = DoIPClient(DOIP_SERVER_IP, DoIP_LOGICAL_ADDRESS, protocol_version=3)
uds_connection = DoIPClientUDSConnector(doip_client)
assert uds_connection.is_open
with Client(uds_connection, request_timeout=4, config=get_uds_client()) as client:

    Foxpi = FoxPiWriteDID(client)
    user_input = [0]
    resp = Foxpi.FoxPi_Ctrl_Enable_Switch(user_input)
    print(resp)

b'\x00'

6.2.4 Driving_Ctrl_toFF()#

將 DID 0x1001 (FoxPi_Driving_Ctrl) 全欄位寫為 FF，用於觸發寫入保護。

Parameters: none
Return type: Bytes (實際寫入的封包內容)，Error 時回傳 None。

Example Code/Output

from doipclient import DoIPClient
from doipclient.connectors import DoIPClientUDSConnector
from udsoncan.client import Client
from common import get_uds_client
from client_config import DOIP_SERVER_IP, DoIP_LOGICAL_ADDRESS
from FoxPi_write import FoxPiWriteDID

doip_client = DoIPClient(DOIP_SERVER_IP, DoIP_LOGICAL_ADDRESS, protocol_version=3)
uds_connection = DoIPClientUDSConnector(doip_client)
assert uds_connection.is_open
with Client(uds_connection, request_timeout=4, config=get_uds_client()) as client:

    Foxpi = FoxPiWriteDID(client)
    resp = Foxpi.Driving_Ctrl_toFF()
    print(resp)
