New way to install ili9341 lcd on latest armbian

[Jarod Adolfo]

I used to be able to easily install ili9341 lcd's on old armbian using, but now it looks like it became much harder now... can you tell me or point me to the right direction to start?

Check if your ili9341 LCD is compatible with the version of Armbian you're using. Also check the physical connections and any required additional components, such as an SPI interface or level shifters. And also make sure you have the latest version of Armbian installed on your device.

Hi there,

 

I recently had an issue with this myself. The newer way to use an ili9341 display is to create a custom dts overlay to initial the drm module. You can use modinfo just check the ili9341 module is present in your kernel. This requires two segments. First request the pins that you will need to use from the port controller, how you do this will depend on the hardware you are using. Normally this will involve configuring what pin to use as the DC pin, CS pin and RST. The second segment is where we enable the SPI bus that we intend to use add attach the display.  NOTE: Do not enable spidev this will cause conflict the ili9341. Please refer to this post: 

 

It refers specifically to the Allwinner/Sunxi hardware which at the very least should provide a basis to start from even if you hardware is slightly different.

 

Best of luck
