I’m trying to establish SPI communication between two Arduinos. When I directly wire pins 10, 11, 12, and 13 of both Arduinos, it works well and I can make them send and receive data.
For a project I’m working on, my idea is to develop a quick connection between both Arduinos, something like a plug-and-play connection, so I thought it was a good idea to use a USB-C adapter to easily connect them. I chose USB-C because it is a cheaper solution in terms of adapters and cables.
I imagine it is a bad idea since it’s not working; there’s no communication between the Arduinos.
Could you tell me is this diagram is right or not + can anyone help me with a code to transfer ultrasonic sensor data?
Attached is the wiring diagram.
Ok got it. Your connection is right. I will send a Guideline right away
I’m not sure this is the right link to me, I’m not confused about ultrasonic sensor, I’m looking for a way to transfer data between 2 arduinos using USB type C. Any thoughts?
Are both end of the cable using type C port ?
Yes Sir
Did you find any interesting information about that mr joseph?
I think is to get a type C female connector for both end and use it on the design. Just my thoughts 🤔
Yes that’s what I did but I just missing the code between them to transfer data
Let me confirm if I can find a library for this
Please, it will help me a lot
I would say you should the original one. Because I onced got an stlink V2, and most of the time my system couldn’t detect it right away. So I say get the original
This is it
