This is a Thread about the original APIXU driver code. I don't use that anymore, having cloned/forked to a different version: wx-ApiXU-Driver. I did that to try and reduce the load on the Hub. Which I think I've accomplished, in the form of splitting the subset of features to run independently and thus introduce gaps in the continuous CPU load.
And like so many other portions of this code, didn't look at what MyTile is doing. I think it's a fixed display hard coded into the driver. I've had one other query into making that 'different' - but I'd only do that in the code I've cloned/forked.
