Arduino Mega 2560 programming example, be sure you have the Mega/2560 wired up so:
Mega Ground to CircuitPython GND
Mega 5V to CircuitPythong USB or make sure the Trinket is powered by USB
Mega 5V to CircuitPython USB or make sure the Trinket is powered by USB
Pin 52 -> CircuitPython SCK
Pin 50 -> CircuitPython MISO - Note this is backwards from what you expect
Pin 51 -> CircuitPython MOSI - Note this is backwards from what you expect
