前辈你好，
已经把Wire.里的BUFFER_LENGTH设为100，但还是编译不通过。请问怎么破？
你是修改过Wire这个库吗？

Tested this library, and had error response F0 and E7.
Then, noticed "remember to set BUFFER_LENGTH to at 64 in Wire.h"

Replaced the comment with
#if BUFFER_LENGTH != 64 #error "set BUFFER_LENGTH to 64 in Wire.h" #endif
Error message appears in platformio when compiling.
