How can I add external RAM for a Cortex M7 controller? Is it even possible and if not is their any other ARM controllers where I could add more RAM to it? By RAM I mean like place to store code and libraries. I plan on having multiple sensors plugged into it, and have it show to an external screen. So I just want to be safe and be able to add more RAM if ever needed. Sorry if it's a stupid question, I am super duper new to this whole ARM world. I would just like to build a device which reads data from some sensors using i2c and then show it on a custom GUI (which would need to be rendered on the ARM Cortex). So having more RAM than not enough RAM would be ideal.
Even if this means I'd have to add some other board to allow memory expansion I would be open to it. Thank you very much all.
I suggest to ask this in the respective forum. If it is an ST chip => ST, if it is an NXP chip => NXP. If it is a self-made chip, then I have no idea where to ask. Maybe in the SoC Design forum.
