Automotive Microcontroller Selection

[jacobanderson]

Hello everyone!

First post on this forum, so please have mercy.

I am looking for a microcontroller to be used in an automotive application to display data coming in via CAN bus. We would like to design a user interface from the ground up using the Qt application and run this application using Linux on our selected microcontroller. Additionally, we would like to have bluetooth wireless connectivity integrated into this same board. This board will also have SD card storage capabilities. The user will interface with this device via a capacitive touch screen in which they can arrange items on screen as they would like.

I have looked into the i.MX as well as the S12HZ microcontroller, but unsure as to which will best fit my needs. The display will have graphics and animations that make for a seamless user experience.

This design is also being used for a school project, so with that being said, an evaluation board is heavily encouraged. Is there such a board out there that can make our lives easier?

What advice and/or suggestions can you supplement us with?

Thanks for your help guys!

Hi Jacob,

Welcome to Freescale Community!

If you require automotive qualified parts, please ensure that you select the automotive part numbers.

For example searching on the i.MX6Q documentation, going to Data Sheets, the automotive document is “i.MX 6Dual/6Quad Automotive and Infotainment Applications Processors - Data Sheet” (IMX6DQAEC):

Hope this will be useful for you.
Best regards!

Hello Jacob,

I would recommend an i.MX processor for your project. You can design the GUI with QT and run it from linux. You can also add a bluetooth device (our boards do not have bluetooth integrated) by usb or pcie.  It includes a touchscreen and sd card.

You can look at the i.MX53 QSB or the i.MX6 SDP boards:

Please take a look at those options and let me know if any fits your needs.
