Measure Frequency with the ESP8266
Posted: Sun Jul 15, 2018 9:11 pmI just got the Sparkfun Blynk Board which runs a ESP8266. I am trying to measure light intensity with the TSL237s-lf sensor, which converts light to a digital frequency signal. I am wondering what code I need to measure and display this data? I have read online that the FreqMeasure library is commonly used but isn't compatible with the ESP9266 timers. I have read a little about ESP8266 timers (like this one http://www.switchdoc.com/2015/10/iot-esp8266-timer-tutorial-arduino-ide/) but I am unsure how to use that to get the frequency measurement. Any ideas? Thanks!
