Python调用Canalyzer发报文

Question

使用Python调用CANalyzer发送报文。目前CANalyzer已经能够运行，可以监听报文，但在发送报文时遇到问题。

from RunAll import *

app = CanoeSync()
total = 0
suc_total = 0
fail_total = 0
app.Start()

while not msvcrt.kbhit():
    EngineSpeed = app.get_SigVal(channel_num=1, msg_name="CemBodyFr103", sig_name="ShortDropWinDrvrDoor", bus_type="CAN")
    print(EngineSpeed)
    app.set_SigVal(channel_num=1, msg_name="CemBodyFr103", sig_name="ShortDropWinDrvrDoor", bus_type="CAN", setValue=2.0)



def Set_SigVal(self, chanel_num, msg_name, sig_name, bus_type, setValue):
        if (self.application != None):
            result = self.application.GetBus(bus_type).GetSignal(chanel_num, msg_name, sig_name)
            result.Value = setValue
        else:
            raise RuntimeError("CANoe is not Open, unable to set signal value")

write打印：System 01-0083 SetSignal was called for signal 'Signal:CAN1/CAN_LEFT/CemBodyFr103/ShortDropWinDrvrDoor', but no signal driver is available.

Answer 1

问题很简单，就是该信号在CANoe环境中是不可获取的，也就是该信号没有被周期发送到总线上，这里你要明白，你能设置的必须是仿真节点的信号，且该信号被周期发送到总线上
