Mitch,
With full confidend I went with the equipment to the race track yesterday evening.
All prepaired well and tested at home.
Hooked up the controller to do some DRY testing on the power adapter.
All worked fine.
Then started the laptop and connected the USB cable for the communication.
When I looked back at the display of the controller all digits were fully lighted.
I unhooked the USB cable to the controller and switched back on but it seems the MEGA 2560 has died :0
So the start was not what I and the other guy expected. But S happens and we then started to concentrate on progrmaming.
At the end of the evening we can retrieve the lookuptable from the MEGA and show it at the Visual Basic CONTROL PANEL side!
As the controller was out of order we could not test your curve lines.
Will discuss your new power curve witht he guy (Gabe) whether or not it is useable.
He was already happy with the fact we can now show what the controller is doing in real time and not guess how the curve exactly is.
He still dreams of drawing his own curve on his smart phone to be used.
In meantime I checked on programming Android app but at this moment out of my league
Have ordered a new MEGA but that will take some time to arrive 2 weeks from China.
Have to check the display this evening with an UNO and if that has gone south too I have to order that one too.
Will add your code in the sketch and add and rework to get the variables adjusted by the menu buttons.
Keep you posted.
Thanks sofar, Paco
