A PYTHON Library for Controlling Motors using SOLO Motor Controllers with RASPBERRY PI, Linux, windows, and more!

Last update: Apr 29, 2022

Overview

SoloPy

SoloPy is a library of SOLO Motor Controllers write in PYTHON compatible also with RASPBERRY PI. It can be used with UART line of RASPBERRY PI or any similar controller to control, command or read all the parameters that are stored or existing in command set of SOLO. More information about it on the SOLO website.

How To Use

Please make sure you have installed Python

Install Solopy From Pip .. code-block:

$ pip install solopy

For List of All the Available Methods Read the DataSheet

Configuring UART on Raspberry Pi

In Raspberry Pi, enter following command in Terminal window to enable UART:: .. code-block:

$ sudo raspi-config

Select -> Interfacing Options
After selecting Interfacing option, select Serial option to enable UART
Then it will ask for login shell to be accessible over Serial, select No shown as follows.
At the end, it will ask for enabling Hardware Serial port, select Yes,
Finally, our UART is enabled for Serial Communication on RX and TX pin of Raspberry Pi 3.
Then, reboot the Raspberry Pi.

Communication within USB

Connect Solo to Raspberry Pi or Pc
Open terminal in linux(cmd in windows) & enter the following command
python -m serial.tools.list_ports -v
get the port name that solo is connected to (in linux it's sth like '/dev/ttyAMC0' and in windows it's sth like 'COM8'

Dependencies

Python 3 pyserial

Testing Examples

To test the examples in Raspberry Pi you might need to put the example files within the "src" folder to be able to compile them The installation of "pyserial" is mandatory, to install that .. code-block:

$ sudo apt-get install python-serial

using brushed DC with Raspberry Pi

Hi,

Short: I would like to use the SoloUno together with my Raspberry Pi to control a brushed DC motor and control its speed. Will there be an example for this in the future? If not, how would I approach it best to parse the Arduino example?

Long: So far, the only example I found that comes close to this is here where an Arduino is used and a potentiometer as input. However I am using a raspberry pi and do not need a potentiometer. Looking at the code for brushless control I have seen that motor_type = 1 stands for BLDC_PMSM. Which number would then be for a brushed DC or where can I find the code documentation? Apart from that the functions would be the same for BLCD and brushed DC right? Only the Piano-Switch setting is different?

Also: When I started the SoloUno with Piano switches 1,2,4,5 Down my brushed DC starts to run immediately and continously. After trying out the brushless examples (I wanted to see what happens using them on the brushed DC). The motor stutters a lot and sometimes runs smoothly. I assume this depends on which of the 3 phases would be selected, since the brushed dc is only connected to 2. If I exit the example, the behaviour continues. So am I assuming right, that the last "action" is saved? Why does then the brushed dc automatically run if I switch on the SoloUno the first time?

Thanks a lot!

name 'solo' is not defined

Hi,

I am just getting started with the Solo Uno and wired it to my Raspberry Pi 4. I did the installation procedure as documented on the github but when I want to test the examples I am getting the error as shown:

Traceback (most recent call last): File "reading_temperature.py", line 38, in <module> do_work() File "reading_temperature.py", line 34, in do_work __setup() File "reading_temperature.py", line 29, in __setup __solo_driver = solo.SoloMotorController(__solo_address) NameError: name 'solo' is not defined

I also wired a brushed dc motor to the solo and my piano settings are all DOWN except for switch 3. The motor is then continuously running.

Thanks for any help!
