Display framebuffer /dev/fb1 on the TFT.

Works for me. Use at your own risk.

Works with 2.8" 320*240 ILI9341 TFT

Tested on v1.2 of this display:

1. Connect the display to the raspberry Pi as below

Display	RPi pin	GPIO #
VCC	1	3.3v
GND	6	gnd
CS	24	8
RESET	13	27
DC	15	22
SDI(MOSI)	19	10
SCK	23	11
LED	33	13

2. Download and install the tft9341 overlay

SSH into the RPI

git clone https://github.com/goodtft/LCD-show.git
cd LCD-show/
sudo cp ./usr/tft9341-overlay.dtb /boot/overlays/tft9341.dtbo

Update the boot/config.txt file

sudo nano /boot/config.txt

add these lines at the end.

# turns spi on
dtparam=spi=on
# loads tft module for /dev/fb1
# 
#dtoverlay=tft9341:rotate=270
dtoverlay=tft9341:rotate=270
# sets tft backlight pin on
gpio=13=op,dh
# or off at startup
#gpio=13=op,dl

3. Reboot and test

sudo reboot

When rebooted, SSH in again.

You can then;

• Check that /dev/fb1 exists

  ls /dev/fb1

• get info about fb1

  fbset -fb /dev/fb1 --info

• test that the display works.

  cat /dev/urandom > /dev/fb1
