Steve,
No I am not sure that I have written the HM software to the SD properly. I am fairly new to the RasPi and don't know a lot about them. Do I need the standard RasPi software as well or do I just need the HM software?
So I just finished building my heatermeter V4.3, and I only get the LCD display and the green and yellow LED's to come on. When the LCD display comes on, I only get black lines on the screen. I am using a RPI 3 B with the heatermeter, which I don't know if I am programing properly or not. Any...
