F303K8 ADC noise when using external 5V power
Hi,
I'm using the following analog pins:
PA0 PA1 PA3 PA4 PA5 PA6
When I power the board from USB the values read in seem stable,if I set the jumpers to power from an external +5V the values read become unstable.
Are there jumper settings I am missing that would rectify this problem?
