I am on Photon 0.7.0-rc.4
I am refining a program that has 4 touch capacitive buttons 1 to 4 each attached to D4, D5, D6 and D7 respectively.
I use button1 to allow detection of a wake by user event from sleep on touching the button1.
System.sleep(button1, RISING, SLEEPTIME);
All the pins are setup thus:
I am also using the same pin to re-light a dimmed screen attached to an ISR thus:
attachInterrupt(button1, wakeupButtonPressed, FALLING); The ISR routine simply sets a volatile bool which is detected and reset in the application.
This was all working fine. I then tried to add an ISR thus to each button;
attachInterrupt(button1, button1Pressed, RISING);
The idea being to note the time using millis() that the button was pressed (volatile uint32_t used) so that in the application I could tell whether the button had been pressed and held for a certain period. This does not appear to be working - can I assume that attachInterrupt can only be used once per pin even if the ISR and mode are different?
