Disconnect any devices
Connect (Vpu to +5V) and (ADC to +3.3V)
Space to continue

The analog pin test fails, with the voltages being a bit low. I thought to try a smaller jumper but the voltage still comes in too low. It was working well before, I wonder what I need to do next to debug?
So when I go to just try out a simple I2C pull-up setup, the device apparently fails! I wonder if I killed it somehow when I started using it after a few months...
Attached log of that below:
Code: [Select]
(1)>4
Set speed:
1. ~5KHz
2. ~50KHz
3. ~100KHz
4. ~400KHz
(1)>1
Ready
I2C>P
Pull-up resistors ON
Warning: no voltage on Vpullup pin
I2C>W
VREG too low, is there a short?
Power supplies OFF
I2C>
Harumph!
