Hello all, I’m brand new to LVGL (just found out about it today), and I’m excited at it’s capabilities and flexibility. I was wondering what is considered the best MCU to power a ~5", 800x480 display? Has anybody done any bench markings with side by side comparisons?
For my needs, the speediest most responsive UI is the most important aspect of my project’s user experience. I’d like to see smooth animations, smooth full screen text scrolling, opacity, and constant updating of multiple text\label objects. I’m looking for an Arduino compatible MCU that will be responsible for driving a 5" TFT touch screen. All of my IO and peripherals will be controlled by a lower cost, slower MCU (Arduino nano or mini or something similar like a custom board design) and connected by serial to the display’s MCU (similar to how a Nextion display works).
With the recent announcement of the Teensy 4.1 (a Cortex-M7 processor at 600 MHz) Seems like more then enough power for a display. Is it too much power? Would a less expensive MCU be more comparable and would users even see a difference between the two? Would a Teensy 4.1, with all of it’s IO and speed be enough to smoothly drive a display AND manage peripheral devices, foregoing my second peripheral MCU? I’m most familiar with ESP32, SAMD51 and standard Atmel/Arduino boards. So working with the Teensy would be new for me.
At this point, I’m not concerned with the cost of the MCU, I just want to know what Arduino compatible MCU would offer the smoothest experience. Any advice and guidance would be much appreciated.
PS: I’m more of a Technologist/Product Designer then I am a graphics engineer. So I may get lost in some of the “math” talk that this topic may produce.
