Hello guys, does speeduino support CAN network? If so how can I implement it?

I will use the CAN network to send data to a display.

Hi, currently canbus is only supported directly when teensy 3.5 MCU is in use .
If you want to use a mega as MCU then you would need an interface such as my gpio module( see wiki under third party devices)

The canbus is 500k @11bit format.
The wiki shows how to enable the output.
The data protocol is STD OBD2 format.

Ok

How can I use mcu teensy 3.5? Is any modification to the firmware necessary? Does it work at 16mhz or more?

Thank you

you need a Teensy compatible ECU board, No modification is needed in the firmware and i think the teensy is clocked at around 160mhz .

Lookup the specs for teensy 3.5 on the pjrc website.
You can use any of the official speeduino boards(and those 3rd party that use a plugin mega MCU board) , there is an adaptor board available to allow fitment of the teensy in place of the mega MCU board.

Got it, and how do I set up the canbus on teensy? Do I use serial 2 or can inputs (CAN0TX, CAN0RX)?


thank you

Use can0 , don't forget you need a transceiver .
If you are using the teensy to mega adaptor then the can pins are brought out to a header already.
There is plenty info online on wiring up teensy to use the can ports.

Ok, and is it possible to connect the pc with the tunerstudio on the can network? Using a Can to Usb converter maybe?

thank you

Uhhh.... No....

Why would you do that when the Arduino has a perfectly usable USB port on it?

I thought I could improve connectivity by reducing noise.
