I had my first heatermeter 4.0 with the raspberry pi working and in the case, and while trouble shooting the blower power out with a meter I goofed and let the smoke out.
Upon rebooting it the heatermeter board actually booted but was not driving the lcd and while I could see values for the probes via the web interface it was glichy and cutting on and off. I purchased a replacement atmega, lcd and 16mhz resonator and now the heater meter appears to be working correctly via the web interface but I still get nothing from the lcd.
I have tried adjusting the contrast pot but it does not appear to do anything. Can anyone point me in the right direction for checking that pot or what else I may have messed up?
This was meant to be a birthday present for my father, but now it looks like it will not be finished in time
Thanks for any help
