you keep making these claims that it's harder than it appears but have yet to back them up. I'd be more than happy to update my understanding of the capabilities of these things if you can actually show me limitations of the technology. until then, just saying SPI is harder than that, when I've written the code for a microcontroller to interface to an LCD, at the advent of Google, (so before stack overflow and ChatGPT), and so I deeply know the frustrations of board bring up, doesn't convince me that it's it's my understanding that's wrong, but yours.
