The mtConnect event:

The mtConnect() event handler is called whenever the PC browser connects to your device.

You can use this handler to perform initializations that need to happen when connection is first established, like updating / displaying certain variables, or sending the current states of everything, so PC browser display starts out right (i.e., displaying the current states of everything.

In that spirit, here is we customized mtConnect() in our PICDEM.net2 project. The lines shown in red are lines we either added or enabled (by removing comment operators) in the code:

void mtConnect(void)
{
  // Example of mtConnect event code --------------
  //
  // Call user-defined sendLedStates() routine,
  // to tell the browser the states of all the LEDs
  //
  //sendLedStates();


  // ********* Add your mtConnect event code here: *********
  // OK, let's activate the sendLedStates() function below, and USE it
  sendLedStates();


} // mtConnect() 
 

// CHANGED BY HAND: Enable this function
void sendLedStates(void)
{
  // Set all the transmit flags

  D1TxFlag = 1;
  D2TxFlag = 1;
  D3TxFlag = 1;
  D4TxFlag = 1;
  D5TxFlag = 1;
  D6TxFlag = 1;
  D7TxFlag = 1;
  D8TxFlag = 1;

} // sendLedStates()
