How to measure frequency on blueduino?


none of the arduino libraries seem to work. pulseIn is also not working. please help


i did some digging on the freqmeasure library. it uses pin 32 on the 32U4 as input which is D13 according to blueduino schematic but is not available as its used for i guess bluetooth? is there a way to measure freq ?


Do you mean measure the advertising interval? It can be done with AT command. Find more details about AT+ADVI at our wiki.


no. measuring frequency from an analog frequency input. i can’t use timer 3 because it is used by the bluetooth module. the pulsein function is not working on this
