CANoe控制程控电源CAPL代码

以下是一个示例的CANoe控制程控电源的CAPL代码：

variables
{
  msTimer timer; // 定义一个计时器变量
}

on start
{
  // 打开程控电源的连接
  powConnect("COM1", 9600);

  // 设置计时器为1秒
  setTimer(timer, 1000);
}

on timer timer
{
  // 发送开机命令到程控电源
  powSendString("ON");

  // 等待2秒，确保电源已经开启
  delay(2000);

  // 发送关闭命令到程控电源
  powSendString("OFF");

  // 等待2秒，确保电源已经关闭
  delay(2000);

  // 重新设置计时器为1秒
  setTimer(timer, 1000);
}

on stop
{
  // 关闭程控电源的连接
  powDisconnect();
}

以上代码中，我们使用了CANoe提供的程控电源API函数来控制程控电源的开启和关闭。我们还使用了一个计时器来定时执行开关电源的操作。在程序启动时，我们首先打开电源的连接并设置计时器。每当计时器触发时，我们就发送开机命令到电源，等待2秒后发送关闭命令，再等待2秒后重新设置计时器。在程序停止时，我们关闭电源的连接。

CANoe 控制USBTMC连接程控电源代码

以下是使用CANoe控制USBTMC连接程控电源的示例代码：

variables
{
  byte usbTmcBuf[1024];
  word usbTmcBufLen;
  long handle;
}

on start
{
  //打开USBTMC连接
  handle = Tester_Init("USB0::0x1234::0x5678::TS1234");

  if (handle == -1)
  {
    write("无法打开USBTMC连接");
    return;
  }

  //发送命令以启动电源
  sendCmd(":OUTP ON", usbTmcBuf, usbTmcBufLen, handle);
}

void sendCmd(char* cmd, byte* buf, word& bufLen, long handle)
{
  int ret = _USB_TMC_SendCmd(handle, cmd, strlen(cmd), buf, sizeof(buf), bufLen, 1000);
  if (ret != 0)
  {
    write("发送命令失败");
    return;
  }
}

上述代码中，我们使用了CANoe提供的_USB_TMC_SendCmd函数来发送命令，并通过该函数返回的buf和bufLen参数获取应答信息。其中，handle参数表示USBTMC连接的句柄，可以使用Tester_Init函数来获取。在本示例中，我们通过发送":OUTP ON"命令来启动电源。

在代码中，我们使用了VISA库（Virtual Instrument Software Architecture），通过USB连接程控电源，控制电源的输出电压和电流，并查询电源的输出电压和电流。你需要将代码中的"USB[0-9]*::0xXXXX::0xXXXX::XXXXXXXX::INSTR"替换成你的程控电源的VISA资源描述符。
