Hi there I bought 2 HSR-2645CRH continuous rotation servos and I need to connect them to Arduino using PCA9685, I looked over the internet and I could not find
how to set these values
I faced this on one of my robot arms. I modified a std servo to be continuous, and used PWM, but, when I swapped it out for an ACTUAL continuous rotation servo, and tried to use the same code, it failed miserably
If you look at this page, way down near the bottom, you might find what you need
Now, I used a raspi with the python code for mine, and I haven't tried the curcuit-python for arduino, but Bill has a primer on circuit-python for the rp2040, and support has increased substantially since then
@spyder Thank you so much for your reply, is it possible to know from where you got that page? so it looks that to accurate results continuous servo is not a good choice, right?
On my screen, the color for linked text doesn't show up much different from regular text, so it might be the same for you, but if you look closely, you might be able to notice that the word "this" in the following is highlighted, and will take you to the page where I got that from...

There is also a link in the following where it says "primer on circuit-python"...

Now, as to whether or not a continuous rotation or std servo better fits your needs, only you can decide that depending on how it's being used. For me, I have the servo I referenced connected to a set of gears that needed to spin more than 360 in order to move the arm, so I needed either a motor, or a continuous servo, but since I'm not the one designing or building your robot, I'm not in any position to consider which best suits your needs
