Hi
I have today completed the installation on my mill of my touch DRO. I'm very pleased with it, thank you for making it available.
However I have a couple of questions. I have built it with battery backup as described elsewhere on this site but I noticed when it is turned off and relying on the battery backup there is an LED on the MSP430 glowing green. This prompted frenzied checking of connections and I established that the battery backup was fine and the diodes were the right way around. However when I disconnected the data lines the LED went off. It is not the green LED - I thought it was D2 - but having looked at the board diagram it must be the multicolour LED (because D2 is red).
It is using Shahe scales with V2 firmware and a V2 MSP430.
Has anyone else noticed this? Does it matter - it seems as though it must shorten battery life.
My other observation is that the display seems to "flash" and change position - too fast to really see what's going on but it might be flashing up an absolute value for a fraction of a second. Has anyone else noticed that?
Thanks.
Russell
