Bob about encoder HOT 3 OPEN

Hi John I was reluctant to submit this feeling there was something I had missed. I now have all nine encoders working after changing #define INTERRUPT_PERIOD 250!!!!! I AM VERY, VERY, HAPPY. I had 4 encoders working _Period 25, after your email 5 encoders working with _PERIOD 50. 9 encoder tried 133 then 125 and finally _PERIOD 250 got them all working. To try and understand what was happening I put in the: void loop() { Serial.print("Top of LOOP");Serial.print(" ");Serial.println(millis()); // X2 = encoder.deltaTick2(); X2new += X2; Single encoder X1 = enc1.deltaTick2(); X1new += X1; X2 = enc2.deltaTick2(); X2new += X2; X3 = enc3.deltaTick2(); X3new += X3; X4 = enc4.deltaTick2(); X4new += X4; X5 = enc5.deltaTick2(); X5new += X5; X6 = enc6.deltaTick2(); X6new += X6; X7 = enc7.deltaTick2(); X7new += X7; X8 = enc8.deltaTick2(); X8new += X8; X9 = enc9.deltaTick2(); X9new += X9; Then by using the Serial Monitor I could see it print ‘Top of Loop’ + millis() then never get back to the top, it would just freeze.. John please advise how I can make a contribution to yourself for this brilliant coding.

I don't fully understand what you mean by "go to the void loop". Do you mean the execution appears to go frozen, or unresponsible? I can think on a possible cause for that, but I have not checked myself. My theory is that the interrupt handle code may be taking too long to complete so the interrupts are interrupting themselves, thus possibly causing all sort of weirdness. If that's the case, then this should be solved by reducing the interrupt frequency. To do so just set INTERRUPT_PERIOD to a bigger value in the encoder.h file. The default is 25, which is extremely short for most needs. Try to set it to 50 or 133 as per the comments in the .h file. — Reply to this email directly, view it on GitHub <#10 (comment)> , or unsubscribe <https://github.com/notifications/unsubscribe-auth/A2YM5XQCWVN34KZJVAK7YZ3WB7QJJANCNFSM6AAAAAAQ7LQSP4> .
