有人能回答问题吗???anyway 
From the sparkfun/ LED_Array_8x7 Github repo, it says
the library supports any ATmega 328-based Arduino.
and XIAO is based on ATSAMD21G18A-MU based on one. and can you share what kind of display you are using, I try to find lib that compatible with XIAO.
i see。。。
Thank you very much for your answer!
The LED module I use is sparkfun_7*8_led
