Hi I am developing a car interface with 3.5" nextion hmi. Many functions on car will be controlled by nextion hmi and arduino so I have to add and define about 100 components(button , slider , picture vs).
I have to use arduino pro mini(sram=2kb) , nano(sram=2kb) or genuino micro (sram=2.5kb)
I can’t use Arduino mega because of measurements.
Is there a way to reduce library size?
I uploaded my sketch to check.
