Run the simulation and click the Test Resistance button to take a resistance reading.

The console window shows the comms between the PC and the Arduino Uno.
I'm curently not overly happy with the results. With a series resistor of 1K and a test resistor of 100R I am reading 116R.
What we have so far is very basic and works to give a ballpark resistance but it's not overly accurate. I think we can make it much better.
I've come across this from Velleman and it looks like it uses several series resistors (R7-R9, R11-R13) that can be switched in and out to try and help home in on a better value and acheive the best reading possible.
Unfortunately I'm unable to test until I can get the app developer package enabled.
Is this missing from your licence? Some of the early licences were created without App Developer support, in which case you will need David to update the licence. If this is the case, let me know and I'll try to get this sorted today.

Hi Steve/Martin,
I also have no license for App developer just to say Only realized when trying to play with the project

App Developer licences for VCs should now be sorted. You'll need to re-apply your licence via Licensing...Manage.

Hello All,
I think I'm going to change tack on thie project slightly and instead of using the SCADA Slave interface I will make custom Flowcode firmware for an embedded device and along with a simple circuit we can then connect this to App Developer via USB or WIFI.
The SCADA slave interface is great but can't compare with custom firmware and ideally all the App Developer should have to do is say do a scan and the firmware checks to see what type of device is connected and do a fully automated test returning the appropriate charecteristics.
The code is complex and designed for multiple targets but I will have a go at porting it into Flowcode and adding some comms options. The fall back option is to compile as is (with some mods) onto an Arduino and then connect this to App Developer
Let me know if you have any comments or suggestions.
