[Makecode Extension Update](../../Makecode/makecode_extensionUpdate) ## 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. ### 3: Why does the text disappear after a short while? · A: Since the dislay of the KOI keeps refreshing, the text cannot persist on the screen for a long time. For displaying persisting text, considering connecting an I2C OLED screen.
