I am trying to use A3 and D2 in a Photon at the same time but for two different porpoises. D2 will be an interrupt while A3 will be an ADC reading.
The documentation says:
Please note following are the pins for which EXTI lines are shared so only one can work at a time:
- D1, A4
- D2, A0, A3
- D3, DAC
- D4, A1
I can assume that this means that I can only use per line ONE of it as interrupts at the same time. (Example: Only D1 or A4… Or only D3 or DAC). But They can be used simultaneously for different porpoises when only one will be used as interrupt?
Just wanting to make sure
