Help please, killed my RA

[poolman]

Hi All

Just as I thought I might be getting somewhere, my controller has crashed and I cannot get it back again.

I had almost everything working and when I looked at the screen on the controller I saw it was dead, I repowered it, I reloaded my latest code, cant attach via wifi etc. looks like all the relays are dead to. I do have power going to the controller and wifi module, both have green leds on.

I have reloaded memory and the screen comes back on, as soon as I try to load a sketch the screen goes off, it looks like the sketch loads correctly but everything is dead except for the green leds.

I have tried loading old memory files and old sketches, but results are the same.

Any suggestions

Thanks

Bryan

I have an update, the problem appears to be the expansion hub, as soon as I plug this in, the LCD goes blank, pull the USB out and the screen comes back on????
