I regard writing encoderPos - instead of encoderPos- as a perversion and suggest deleting that unnecessary space.Īs you haven't shown the PinB() interrupt handler, I don't know how you were going to handle the encoderPos++ case. In my opinion, that's a stupid and unnecessary feature I suggest that in your code you use standard C notation like 0B00001100 when you want to use binary constant values. That is, in the Arduino software environment, constant B00001100 has the value 0B00001100. The Arduino software environment defines constants like B00001100 with binary values that match the name. Similarly, delete the sei() at the end of PinA() because hardware restores interrupt status when a RETI instruction executes. Because hardware disables interrupts before it enters an interrupt handler, there is no need for the interrupt handler to turn off interrupts. PinA() is an interrupt handler, connected to interrupts by your attachInterrupt() calls. So the first if condition in PinA() is never met. Here are a few problems with the code shown in the question:ĪFlag is initialized to zero, and is never set nonzero in the code shown. See the sections “Using other pins for PCIs” and “ISR-framework-generating Sketch”. Note, in an answer at Can external interrupts be OR'd together on the '328 (Uno)? I show a couple of routines that will display appropriate masks for pins on different Arduinos. On the Mega, INT0.INT3 are PD0.PD3, and INT4,INT5 are PE4,PE5. Mega2560's have six INTx pins, vs two such on Uno's. I think on the Mega they are PORTH3 and PORTH4 respectively”, it's true that Arduino digital pins 2 and 3 belong to different ports on Uno vs Mega2560 boards.
