I want to program a device using a Flasher STM8 over the SWIM interface that may already be powered.
1. How do I handle connecting the two power supplies?
2. Will shorting the two power supplies together cause problems?
3. Must the Flasher's +5V be connected to the target's +5V? ...To sense the supply voltage for example.
