Hi, I have connecte an MD04 to control a motor. I have plugged it to a raspberry by USB… I have written a short code in python and using pyserial and I am able to set/read baud rate, operation mode, etc. but if I set speed or acceleration it does not do anything, register does not change. I measure voltage V+ and G and I have the right reading but M-M is always zero
I have checked motor and it is working if I connect it directly.
I am using the addresses located at datasheet of MD04, but setting speed, acceleration or direction does not seem to work. The others work fine. Can you please tell me what I am doing wrong?
Thanks
Hello @winter1 and welcome to the forum.
From your post, seems that you used this controller: https://www.robotshop.com/en/md04-24v-20a-h-bridge-usb-dc-motor-driver.html
And you used this datasheet: https://www.robotshop.com/media/files/pdf/md04tech.pdf
Which motor did you use?
It would be good if you can post a scheme and a photo of your wiring and also your Python code!
