Load an image from mcu

Hi, I 'm building a weather station with news and I' ve see that I can't load any image but they must be loaded with editor only, do you think it's possible to do? Send another image from arduino to Nextion? Really thanks

This would be very handy to send an image over serial to the Nextion.

That would be very useful.

I am now reviewing all of the Feature Requests, this will take some time, patience please.

It takes some crafty mcu code to be able to

- read the image format

- for each pixel, determine and convert color into 565 color format

- issue line command to color new pixel

- real crafty to achieve better than 433 pixels processed per second

No means to store picture on Nextion unless it is in the HMI

- meaning this slow process above needs to be completed every image change


The HMI advantage is the speed to display an image included in the HMI file

- this image is local in SPI flash and therefore many fold faster than UART

Not very effective over UART, but documented
