Hello,
I compiled a project for Seeeduino XIAO and got an error in the VARIANT.h file. The error stated that in line #219 the #endif had too many parameters. I checked and it seems that there is a missing “//”. When corrected the compilation had passed.
The file path is %path%Arduino15\packages\Seeeduino\hardware\samd\1.8.4\variants\XIAO_m0
The modified line: #endif // SerialUSB
Regards
Yona Gy
