Re: W8TEE TFT/ VFO DISPLAY BOARD BOARD

I must have missed this in the build or setup. The voltage continues to change so it must be floating. I have the tft/vfo connected to the bitx40 power so don't think I have a ground problem. Could you resend the detail about the voltage divider 

"If you connect the display voltage pin to your voltage source, it will flash one or two times at power up, but will only update itself if there is a measurable change in the supply voltage. My guess is that you don't have yours tied to either ground or a voltage divider. As a result, the pin is floating which is read as a new voltage which triggers a screen update.I had mine running several hours last night and it never varied enough to update the field".
