Vad är Unit Puzzle?
Nyligen lanserade M5Stack en ny produkt som heter Unit Puzzle. Unit Puzzle är en mångfärgad ljusstyrningsenhet bestående av en 8x8 RGB-matris med 64 WS2812E RGB-LEDs.
Jag såg det först på en MakerFaire-show som denna:
Det gör mig glad, ni vet att vi gillar LED väldigt mycket, så jag skaffade genast 10 enheter av pusslet. Låt oss ha lite kul.
Hårdvaruanslutning
När det gäller mikrokontrollern vet ni vad min favorit är. Det stämmer, M5Stack ATOM Lite.
Och enheten inkluderade en unit puzzle, en kontakt, en Grove-kabel. Det betyder att vi kan sätta ihop alla enheter.

Första visning
Mycket perfekt display, men varje pixel 0 var tänd. För konstigt, den borde användas för positionering. Okej, låt oss stänga av den.
Andra version
Jag behöver stänga av pixel 0, ge bokstäverna olika färger.
