I am trying to do a digital car gauge. The response time of the screen is very important.
Now even drawing a simple 1 color bitmap is slow. I know that it's all about clever code, but if it loads bitmap visibly slow, how can it do more things..
Is it possible to achieve a almost no delay effect?
Or should I switch to something else? nextion?
