They released a driver a while ago through windows update that stops it working. You can download the old ...

Assuming your gauge control in the interface is named IPGauge5, you should send something like this from your Arduino:


Serial.print("{UI|SET|IPGauge5.Value=");
Serial.print(linearSpeedKmh);
Serial.println("}");


A few important notes:

Use UI as the prefix

Use the SET command

Use the .Value ...

Hi, currently this is not possible. The merged source only works in the inwards direction (you can see this when you ad a monitor with the merged source and it wont let you send data out). We have it on our todo list to investigate options around sending outgoing messages to both sources

Got creative and I think this would work for 2 or more radio buttons. MegunoLink interface file attached.

Hi Alf, did you figure this out? You should just be able to click the connection manager visualizer on the right side of the screenshot you have shown?

Hi yes, in our interface panel visualiser you can drop a SerialConnection object that will send a message after some delay when a connection is established. You could also implement something like this where it would be able to tell if megunolink is connected or not at all times.

Can you please share your program with me and ill take a look.

Yes, it is possible to have two interface panels on a single MegunoLink interface. MegunoLink allows multiple panels to be added to a single project interface. Each panel can be configured independently to handle different tasks, such as plotting data, displaying text, or controlling connected ...
