I installed a CR servo that came with my Dev kit. It works as it should in the ezb builder. I bought and upgraded HiTec Robot servo model HSR-2645CR and when I try it it starts moving in one direction but then I cant control it. It wont stop or switch directions. I am using port D0 and have tried others and get the same problem. I have not tried an ADC port.
Do not plug into the adc ports. It could be possible that your servo is broken.
Your ez-b could also be browning out. What else is connected to the ez-b? Try running it as the only thing connected to the ez-b.
I thought about that. Its the only thing plugged into the ezb. Its as wide input servo. 4.8-7.4v. Its a brand new servo and I'm not sure how to test it if it is bad.
You only bought one? What were you going to make with it?
there's a tutorial on the ports for the dev kit which explains the difference between digital and adc ports. I recommend reviewing the tutorial as a side note - to ensure you do not connect things to the wrong port and damage the ezb
. That wouldn't be good! The tutorial is step by step with great information and isn't very long. Each step should only take a few minutes of your time to read. Always smart to learn from facts rather than mistakes
if you connected the hitech servo correct with the ground and signal pin in the right orientation, used a brand new add control of a modified servo control, and it doesn't work as expected, I would assume the servo is damaged. Contact the supplier of where you got it from.
I should also add that there is a small chance the servo is not following standards. Well, there's an enormous chance that it isn't following standard - because not many servos do. Also, the servo May by a Chinese knock off of the Chinese hitech brand. It's real hard to tell the difference, sometimes impossible.
So if that's the case, you can try tweaking the values for the two directions. When you tweak the values in a modified servo movement panel, there's a test button. Try adjusting the values closer to each other and hitting test to see if you get expected behavior.
I only bought one of these types of servos because its for a BB-8 robot project. I have plenty of 180 servos. I wanted a high torque CR. I have it plugged in correctly so its either something I'm not doing correctly in the builder or the servo is bad.
Try my second post - incase u missed it, about the values. See if tweaking helps.
What is odd is that if I set the servo up as a Horizontal servo and adjust the values to min 1 and max 180. It works as it should changing direction and continuous. To stop it I have to bring it back to 108.
