LCD Orientation

One advantage of the KOI is that camera is able to rotate from 0°~180°, however the image may be reversed on the LCD when the camera is rotated, thus we may need to change the LED orientation based on our use case.

Makecode Extension Update


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.
