The confusing part is about the registers. I can't figure out what you mean by that. Heat sinks on motor drivers?
First thing Sdk does is read accelerometers to establish frame of reference, otherwise commands like moveTo(x,y,z) make no sense as it doesn't know where end effector starts. And that is the part that hangs firmware when accelerometers are nowhere to find. If you look at Sdk implementation you can see how to set initial arm angles statically so that it can skip requesting accelerometers.
If the driver example moves motors infinitely until you stop the script then everything except accelerometers works as expected.
Don't forget to buy ferrite beads, you'll need them to make GY-521 work. Otherwise there is too much interference from motors.
I see, MAx. What I meant about registers(resistor 4.7k; It's my mistake of typing..) comes from the file named "interference-fix" in what I downloaded. And you're right. I found that there is infinite process of motors until I stop the script Lastly, to make sense to buy other things, Is it right to purchase one GY-521, four or five ferrite beads for a doobt? Thank you
One accelerometer won't help you much with hanging firmware. Either buy two accelerometers or none, in which case just make Sdk not request them.
You can try with fewer number of ferrite beads. If it works consistently well then you don't need more in your configuration. I used one on each end of each motor wires and one on each end of the I2C wire = 8 overall see this picture
To check if your accelerometers are working just don't power motors to eliminate possible interference. Once they work without motors, power motors up and play with ferrite beads until you get system stable.
To yoo Thanks, yoo. As you said, I bought two GY-521. By the way, Have you ever made your own dobot? If you can help me with what I will talk about, would you back me up technically? If possible to you. I will let you know my email-address or whatever..
To Max Hello, Max. I received some ferrite beads and GY-521. And then I try to compose a circuit based on the folder, docs. However, I found another problem when trying to have connect them...Let you see
