Video of DRO Operating

Video of DRO Operating

I've made a little video of the DRO operating so you can see how fast the update rate is. It's several readings a second and easily fast enough for anything I do. The gauge data stream is pretty fast and all six channels are read by the main processor over I2C, only three are displayed.

The main TFT is quite slow with big updates, but just about responsive enough when I use the menus.

One thing I was worried about was the auto power-off that the gauges have. After a period of inactivity they shut down, but fortunately all they do is turn the display off. The data stream continues, which is perfect for a DRO like this. It also might explain why the batteries go flat so quickly...
