C CommanderLake Member Jan 8, 2022 #1 I need to get a 40X2 to respond at any moment using a hardware interrupt to a falling edge on the "hint0" pin but I cannot get it to interrupt more than once, how do I get the hardware interrupt to work more than once?

J johndo Member Jan 8, 2022 #2 You need to re-issue the setint command AGAIN after the command has been executed and processed.
C CommanderLake Member Jan 8, 2022 #3 But I'm not using polling interrupts I'm using hardware interrupts!
C CommanderLake Member Jan 8, 2022 #4 Found the solution, I have to set flags = 0 before calling setintflags again otherwise it loops.
