Raspberry Pi 3

10 Mar 2018

Salutations I am a student at Northern Arizona University,

I am currently a participating in a robotics competition. I have a degree in Mechanical engineering and I am currently pursuing a second degree in computer science. The robot we are making for the competition is a soccer playing robot this is my first time doing programing like this. I have an understanding in Python and Java. We are using a Raspberry Pi 3 for the brains of the robot. I have installed Raspian and Retropie on-top to facilitate in creating a way to communicate wireless through Bluetooth. I am confused on how to create a program to create methods to layer onto the button events.

Can someone help with documentation I have been searching the web and I have not been successful in acquiring information on the subject at hand. I need an angel, who is out there that can help.

Welcome to the E14 community. Many members are like fire hoses when it comes to providing responses. The more you invest in providing details, the greater the chance you will get hits from first responders.

I have done some extensive work with connecting Bluetooth audio devices. Raspbian Buster (full only) has finally started addressing the issues with the Bluetooth service. Drop me a line and I can send you an article I wrote for a computer magazine. I can't share the resource on a public forum but am willing to share privately with a promise you won't post it.

WOW.................... I have been searching for stuff online for a while now....... I wish I would have subscribed to this site long ago. I am happy that there exists a community that has such interests. I am going to follow these steps and try to get this bot rolling thank you for your help. Cheers I'll post photos of the final build.

This looks like the right documentation for you:
https://core-electronics.com.au/tutorials/using-usb-and-bluetooth-controllers-with-python.html
There is also this:
https://github.com/jalopezsuarez/piback/wiki/Controllers-Bluetooth

The Retropie software isn't needed, the operating system (Linux) is capable of providing you key events through drivers, and these can be collected in Python. From there you can control your motors using the examples in the PDF document that you referred to.

If you were to try to pull hooks from the Retropie software, you'd need to delve into the RetroPie code, make changes and recompile. It would be very unconventional/strange to do it this way, and would be more effort.

I am currently using python3 I have the code documentation on the Motor-shield v.1 for the raspberry pi3 which is provided by www.maker-sphere.co.uk which is actually posted on https://github.com/sbcshop/motor-shield/blob/master/Maker-SphereMotorShieldv1.pdf. So I am using Raspbian for the operating system for the raspberry pi and I am using retropie as an emulator. The emulator runs on boot up and I am able to connect wireless through Bluetooth to the pie by means of the emulator. What I want to do, which is where I am stuck at the moment, is I have no clue how this code should be implemented to the pie in such a way to where my already connected controller may be able to run functions from the code to operate motor ports from the raspberry pie. So in summary I have event clicks happening already I want to code those event clicks somehow to my functions so my program can operate the raspberry pi which will command the motors to operate based off an existing controller.
