Ha, you don't need to be sorry - I'm having a blast - must mean I can partly understand what you are doing
By the way, if you are truly going to keep this Open Source, I think it will be "very" popular - One thing that I would like to see is for you to go overboard with documentation for folks that want to tweak things and learn as I do -
So..... Trial and error ended up with a Volt_GAIN of 3.8 to give the correct 11.0V of the pack ?
Now I see the pack has gone to 10.9 and the OSD is jumping from the 11.0 to 10.6. What happened to the 10.9, 10.8 and 10.7 - I am beginning to suspect the sensor. Do these go bad? I'm using the one as in the schematic.
Maybe I should go back to playing with the ASC756
I notice the ASC756 is what EmmersionRC and Eagle Tree use in their OSD.
Is the ASC756 more accurate and/or sensitive?
