I try to follow this Heart rate using nodemcu, (change Cayenne for Firebase), but I have problems with the Interrupt.ino (I try to change pulsemeter sample code, and have the same problem); is not compatible with Board: "NodeMCU 1.0 (ESP-12E-Module)"

When I choose Board:"Arduino Genuino/Uno" the program compiles OK, but I can't use the mcu to connect with Firebase.

Any solutions for this?

Solution: Change the interrupt.ino of the original project https://github.com/WorldFamousElectronics/PulseSensor_Amped_Arduino for this project interrupt.ino https://github.com/EnvironmentMonitor/Pulse-Sensor-ESP8266-ADC0, the problem; I see is because the Arduino work with timers but the nodemcu not.
