Hands-on with NXP’s MCX FRDM Boards - Workbench Wednesdays

[@kev009]

These are both great dev boards and priced well

Enjoyable coverage of these NXP Products

Ah very handy; Ialso just got these two devkits! whats missing for me now is an arduino core for them

[@bald_engineer]

Agreed. I'd especially like one for the MCX-A since it is more general purpose. I can see it fitting in well with Platform IO.

[@conorstewart2214]

I think to get it to work I’m arduino might limit the features a bit, especially with the NPU in the N947, but if it could be done without many limitations it might be a good option.

Hmm what are some of the things I could do with this? face-recognizing security system?

[@MAYERMAKES]

So far i see the A series seems to target low power applications like battery powered devices, and the N series drives displays and can do image recognition at once. Avnet had an impressive demo with it at embedded world

Total noob here looking to get started in building my own electronics. Could I use the N to make a portable display from an old laptop or tablet? Level of difficulty and / or where to start. Thank you Infinite love and gratitude from Colorado!

While I have not used these particular dev kits, if your just looking for a portable display, using a raspberry pi3 or newer can drive a hdmi port on a lcd screen, provide usb and networking also. Much simpler path than trying to reuse a proprietary display from a tablet/old laptop. Price is only about $35 for the pi 3 to start with plus a used hdmi enabled screen. You can also buy 7-10" screens designed for the pi with a case that it all fits in nicely for about $70. Lots of examples online and use cases. Dont spend your time re-inventing the wheel when starting out. A bit of python programming goes a long way also with the pi and can control the i/o ports and such nicely.

Driving a large laptop display is not trivial. They do not use a protocol like DVI or HDMI. They require a LVDS driver. So, Could the MCX-N do it? I have no doubt. But it would be far from trivial and not a getting started project. As someone else mentioned, if you have a display with a standard interface, like HDMI, then a single board computer with HDMI support is a better starting point.
