Hi! Just got my r4 wifi today, and I'm having trouble getting it to work with servos. As best I can tell, the PWM output on the pin is updated much less frequently than it's supposed to be, resulting in a ticking like behavior on the servo. To eliminate variables right out the door, I am properly p…

Looks like I can't upload videos, so here's self hosted: https://s3.us-west-1.amazonaws.com/bottango.com/TestBuilds/offset.mov On the left, I'm reading the pwm input directly from the r4 on the r3, using pulseIn() with a 10ms delay so it's a little more readable between writes. On the right, that'…

Hi @evanbottango . The Arduino IDE developers are tracking this problem here: PWM duty cycle range not continuous on UNO R4 opened 06:35PM - 07 Jul 23 UTC [ozangerger] ozangerger …

Thanks for the update, glad to know it’s not user error. I’ll keep an eye out for a solve, much appreciated! Excited to see what I can do once that’s fixed :slight_smile:

Edit: @KurtE 's PR (#116) does work! Is there any reason why it's not yet merged? Hi, I am still having the issue described above. Servo library is version 1.2.1: #include <Servo.h> Servo myservo; // create servo object to control a servo // twelve servo objects can be created on most boards i…

Sorry been awhile. It looks like the reviewer still has some edits he wants... Note: my UNO R4 boards are currently in box.... Servos back in storage...

Tacking on to this thread - I tried using a servo with the R4 minima today and immediately encountered extreme servo jitter that I wasn't experiencing with the same circuit and code on an R3. Googled it and immediately found this thread and a bunch of others, so I didn't bother breaking out the osci…

[image] bfinio: So...looks like there's a fix but it's not part of the latest IDE/automatic updates yet? Can anyone clarify? That is correct. Arduino IDE only provides release versions of the libraries. The bug has been fixed (thanks @KurtE!), but there hasn't been a new release of the librar…

Thanks @ptillisch ! Is there any way to get an estimate of when the fix will be officially released - even a very rough timeline, e.g. "sometime in the next week" vs "later this year"? I work for a STEM education nonprofit and we really try to minimize barriers to entry for our teachers/students (e.…

[image] bfinio: Is there any way to get an estimate of when the fix will be officially released Unfortunately I don't have that information. I'm not involved in managing the releases of this library. You can request a new release by submitting an issue to the GitHub repository: ar…

Update for other people finding this - as of May 15th, 2024 it looks like the library is still on version 1.2.1. I submitted a GitHub issue here, will also update this thread if I get a reply on GitHub: Release update that fixes servo jitter issue on R4 · Issue #128 · arduino-libraries/Servo · GitHu…
