FAQ¶

1: There is no reaction after pressing the buttons on the Micro:bit.¶

· A: This is because KOI has a longer boot time than Micro:bit. When the power is turned on, Micro:bit has already ran the code for KOI initialization before KOI is ready.

· Solution: Reset your Micro:bit after KOI has been turned on. (The trick is to let KOI power on completely before initialization.)

2: Does KOI work with 3V input?¶

· A: No, KOI only works with 5V.
