I am looking for fbtft support on kernel for ubuntu-core

Hi

I have NanoPi-M1 board. It has two type of Ubuntu-Core as you can see here(https://www.mediafire.com/folder/3q2911p1qp33p/NanoPi-M1Board#dc73df73c6dk6) with kernels (3.4.39 amd 4.11.2).

But when I try

modinfo fbtft

It says there is no file or directory like this! But I think it should be exist in kernels with version above 4.10.

By the way, I need this kernel support to running my LCD!

 

Are there any Armbian version like Ubunto core with this module support on kernel?

Or can I add this support to yhose Ubuntu files in above link? how?

Kernel 4.13 went out for testing a week ago. Avaliable only for some boards at this moment.3.4 and update to NEXT kernel when it go out to stable repository?

Do you need to have a virtual framebuffer sent to the LCD to accomplish your task, or do you just need to draw text/graphics on the LCD under your control? The reason I ask is that I wrote a simple and fast set of functions to talk directly to SPI connected LCD displays. It doesn't create a virtual frame buffer, but it does offer simple functions to draw text and graphics (https://github.com/bitbank2/SPI_LCD). For some projects, it will be easier to work with (and faster) than sending 'late copies' of a virtual framebuffer to the LCD.

Very thank you Larry!
I will check your project. Where can I ask questions about it?

Can I show images with your library?  Does your library support ILI9481 too? If I use this LCD can I use your library: http://www.sanatbazar.com/shop/shop-main/نمایشگر-3-5-اینچی-320x480-مناسب-برای-آردوینو-uno-و-mega2560

You're welcome to email me (bitbank@pobox.com).  As far as I know, the ili9481 behaves the same as the HX8357 (which I do support in that code). My code was designed for speeding up game emulation and allows you to draw image tiles up to 4K bytes (typical SPI buffer limit). The LCD in your link only talks about its 8-bit parallel interface. My code is strictly for working with SPI (serial) connected displays.

I made an issue inside your github. I thought maybe it's better and easier to ask questions and also other people can see the solution too
