I want to use 2 rotary encoder to logging 2 axles which supporse to spinning in different speed. Is it possible on my Arduino uno board? I wanba use "attachInterrupt" function for this.

Detail depends on details, as per: [image] Best first 5 topics to read to reach Trust Level 1? How to get the best out of this forum by @PerryBebbington -- to learn how to post productive questions. What encoders? What interrupts do you want to attach? How fast will things turn? What will y…

I don't know about specific information or datasheet for my encoder because I took it from junk optical mouse, but it worked when I use one. In theory, both my axles will turn at roughly 3000 rpm at maximum, but I think it won't reach such speed in real life. and here is my code for twin encoder s…

How are the dual encoders attached to the Uno? I only see two encoder pin inputs in that code. Are they both attached to the same encoder? This suggest detailing the connections with a schematic: [image] Best first 5 topics to read to reach Trust Level 1? How to get the best out of this forum…

How are the dual encoders attached to the Uno? From the code it looks like the counting is only counting up. Is that good enough for speed? Yes. I want to masure speed, so I only need 1 input per encoder and count up. Does the code compile? I see that a semicolon is missing within the pulse_co…

[image] cyber_f: Alright. but where to add this? noInterrupts(); int safe_count = count; int safe_count_B = count_B; interrupts; You would use that before you needed the counts. For example: void loop() { zikan = millis(); zikoku = String(zikan); noInterrupts(); int safe_c…

I've built both hardware and software, and here's some issue. 1.interrupts; in your code causes error. message reads: 'interrupts' was not declared in this scope 2.Run the program and turn axles, results in csv file is static number for all Timestamp and both values (as screenshot attached). [ス…

[image] cyber_f: 1.interrupts; in your code causes error. message reads: 'interrupts' was not declared in this scope I’m sorry. Interrupts is a function and I should have typed interrupts(); as in void loop() { zikan = millis(); zikoku = String(zikan); noInterrupts(); int safe_c…

After some experiment, all error is gone. Huge thank you, Dave!
