How to do device integration for Raspberry Pi?

Question

I am making the GUI application for an electric bike to display the speed and the battery percentage. I've made use of the already available example, so I do not have to do anything regarding the development of the gui but the place where I am stuck is, the Device Integration.

 

My question is, do I have to put some operating system in the raspberry pi?

I have to collect the data from GPIO Pins so how do I send this data from the raspberry pi GPIO pins to the GUI application. Should I make use of native statement and write the code that collects the data or should I write in Python, in the Pi's operating system and then somehow collect the data and send it to the GUI?

Hello,

let me refer to the section Accessing Hardware GPIOs within the Getting Started documentation. It demonstrates the access to the GPIOs of the Raspberry Pi.

I think this will be helpful.

My question is, do I have to put some operating system in the raspberry pi? 

This question is not clear to me, the software is based on Raspbian OS (Embedded Linux) - there is no need to add some operating system.

Best regards,

Manfred.

Regarding the unclear part of my question:
Do I have to flash Raspbian OS on to the Pi.

Now the things are getting a little clear. I will ask if I need any further assistance.

Thank you very much for the reply.
