Frequency measurement using capture in SAMD21

Trying to use the capture function of SAMD21 in Seeeduino XIAO for frequency measurement in ARDUINO IDE. Tried to create a sketch for the same but could not do so. Any help would be appreciated

Hmmm, Well @ stuff343 I don’t have my “Kreskin” hat on so I don’t see the code, but alphabet man shows this and It looks pretty cool. Frequency measurement on Seeeduino Xiao at 200kHz
