Interrupt on ESP
Posted: Sat Feb 18, 2017 1:46 pmHi there,
I try to build a solution that wateres my plants based on their humidity. Therefore I first used an UNO, till I wanted to expand it with Wifi. I bought a Wemos D1 mini that is based on an ESP8266, but now parts of my code doesn't work anymore.
As humidity sensor I use the following sensor: http://www.mikrocontroller.net/topic/335407 and I try to fetch the information with interrupts. The following code worked on the UNO, but doesn't with the ESP:
The problem is, that the wdt resets with the error code 4 and I dont know how to avoid that. I basically want to get the humidity from this sensor.
I already tried:
- deactivate wdt with ESP.wdtDeactivate()
- comment out the delay, but the result is always 0
- comment out detachInterrupt
- added attachInterrupt into setup
Has anyone a clue how to get this work on ESP?
Thanks a lot!

Code: Select all
volatile unsigned int pulse;

{
// ESP > 115200
Serial.begin(9600);
}
void loop()
{
interrupt(0);
Serial.println(pulse);
delay(1000);
interrupt(1);
Serial.println(pulse);
delay(2000);
}
void count()
{
pulse++;
}
void interrupt(int pin)
{
pulse = 0;
attachInterrupt(pin, count, RISING);
delay(20 * 10);
detachInterrupt(pin);
pulse = pulse / 20;
}
